increased blood pressure (Ribeiro and Sebastião 2010). In addition, caffeine stimulates the release of catecholamines (e.g., noradrenaline, adrenaline) from the adrenal glands, leading to increased heart rate and cardiac output and peripheral
vasoconstriction. Other issues associated with caffeine intake may include the stimulation of renin release from the kidneys through the release of angiotensin II, a
potent vasoconstrictor which stimulates the release of aldosterone, leading to
sodium and water retention, further contributing to increased blood pressure
(Tanuma et al. 2003). Another caffeine effect involves the impairment of insulin
sensitivity and glucose metabolism, both representing risk factors for hypertension
and cardiovascular disease (Sakr etal. 2023). A recent meta-analysis and systematic
review by Chen etal. (2022) observed that caffeine exposure during pregnancy was
not signicantly associated with the risk of gestational hypertension or preeclampsia, suggesting that more prospective and long-term studies should be implemented to draw up denitive conclusions. Santana etal. (2024) concluded in their
systematic review that the evidence so far published is insufcient to conrm with
certainty that prenatal caffeine exposure may lead to neurobehavioural disorders in
the newborns. In conclusion, evidence supports the recommendation of a caffeine
consumption up to 300mg daily in healthy pregnant women as an intake that is
generally not associated with adverse reproductive and developmental effects (Chen
etal. 2022; Wikoff etal. 2017).
Furthermore, tea and other consumed beverages which could contain bioactive
compounds including caffeine, catechins and polyphenols have been investigated in
their potential detrimental impact on gestational, foetal and neonatal outcomes
(Arafa etal. 2024). The highest frequencies of antenatal tea drinking were associated with increased ORs of hypertensive disorders of pregnancy (OR=1.16) (Arafa
etal. 2024). Therefore, it could be prudent for pregnant women to minimize tea
consumption as well. However, well-designed prospective cohort studies are needed
to establish causality and explore potential dose-response relationships between tea
consumption during pregnancy and gestational and/or foetal and/or neonatal
outcomes.

22.3 Cannabis andCannabimimetics Use During
thePerinatal Period
Cannabis sativa L. (aka Canapa, Indian Canapa, Marijuana, Mary Jane, Hashish,
pot, herb, Maria, Hagga, Puf, Maconha, etc.) is a commonly used drug during preg-
nancy, with its use having increased among pregnant women in recent years (YoungWolff etal. 2017, 2019). Epidemiological evidence shows that cannabis use during
the gestational period is quite common, ranging from 3% to 16% worldwide reaching higher levels in some demographic subgroups (Angeliki Gerede etal. 2024).
Marijuana has antiemetic properties, and prenatal cannabis use is most prevalent in
the rst trimester of pregnancy for managing nausea and vomiting in pregnancy and
hyperemesis syndrome (Ainiti et al. 2023). In addition, marijuana use can be
reported among pregnant women to self-manage other pregnancy-related

22 Substance Use Disorders
471
symptoms, including anxiety, depression, pain or for recreational purposes (YoungWolff et al. 2019; Brown etal. 2019). Cannabis passes placental transfer to the
foetus (Pertwee 2010) and its levels can be detected in the cord (Hanuš 2007) with
levels which are proportionately smaller than those of the mother (Hanuš 2007). In
urine samples of neonates, signicant levels of cannabis have been detected
(Al-Hayani etal. 2001). The potentially adverse effects of marijuana use during
pregnancy are aggravated by the consumption of high potency marijuana (i.e., marijuana consisting of high Δ9-THC content of 9% or higher), with the risk of an
increased effect in developing central nervous system anomalies of embryo/foetus
(Psychoyos and Vinod 2013).
In utero exposure to cannabis has also been associated with increased neonatal
care requirements and risk for miscarriage (Gurm etal. 2021). Furthermore, cognitive, motor and social dysfunctions as well as neurobehavioural complications have
been described in the offspring following maternal exposure to cannabis during
pregnancy (Orsolini etal. 2017). Indeed, prenatal cannabis exposure has been linked
to a wide range of effects in offspring, including:
1. Cognitive impairments: Studies showed that cannabis exposure during preg-
nancy negatively impacts foetal neurodevelopment reducing performance in
cognitive domains such as verbal language, memory and visual function (Gurm
etal. 2021; Ramon Portillo etal. 2024). Cannabidiol (CBD) can disrupt tryptophan metabolism in the human placenta, altering the balance of serotonin and
kynurenine (KYN) pathways thus possibly increasing the risk of cognitive
impairments in newborns and small-for-gestational-age births (Ramon Portillo
etal. 2024). Prenatal cannabis exposure has been linked to changes in the development of fronto-limbic white matter, particularly the fornix, a critical pathway
for emotional learning and memory (Evanski etal. 2023). These decits may be
persistent thus extending into childhood, adolescence, and even adulthood
(Murnan etal. 2021).
2. Neuro-behavioural effects: Prenatal cannabis exposure is associated with
increased impulsivity, hyperactivity, and emotional dysregulation in children
(Odom etal. 2020). THC, CBD, and their combination can produce sex-specic
behavioural changes during adolescence, such as altered impulsivity, anxiety,
memory, and sensory gating (DeVuono etal. 2024).
3. Psychiatric illnesses: Children exposed to cannabis during intrauterine life show
a higher likelihood of developing ADHD symptoms/disorders, psychotic-like
experiences and autism spectrum disorder (Tadesse etal. 2024; Paul etal. 2021).
4. Physical abnormalities: Perinatal cannabis exposure is associated with gastros-
chisis, particularly in mothers aged over 34, although further research is required
to determine causality and age-related variations (Delker etal. 2024).
Studies observed that the above-mentioned risks are dose- and time-dependent,
with increased levels of prenatal cannabis exposure associated with higher risks to
induce detrimental obstetrical, foetal and neonatal effects (Klebanoff etal. 2021).
According to a recent systematic review and meta-analysis, among all associations

472
L. Orsolini et al.
documented so far in the published literature between cannabis exposure and a specic set of gestational, foetal and neonatal outcomes, only two outcomes presented
convincing evidence of in utero cannabinoids exposure harmful effects, i.e., low
birth weight (OR=1.43) and small for gestational age (OR=1.61) with Class I
evidence (Solmi etal. 2008). Conversely, preterm delivery (OR=1.32) and neonatal
intensive care unit admission (OR=1.41) displayed Class III evidence following in
utero cannabis exposure (Solmi etal. 2008). Current literature conducted on humans
still lacks solid association data which limits them to draw denitive conclusions,
due to potential concomitant confounding variables such as polysubstance use and
lifestyle issues. However, due to signicant concerns regarding impaired neurodevelopment, as well as maternal and foetal exposure to the adverse effects of marijuana consumption, pregnant women or those contemplating pregnancy should be
encouraged to discontinue cannabis and cannabis-like products. Before pregnancy
and in early pregnancy, clinicians should always be asked to all women about their
current and/or recent/past use of marijuana, investigating motivations and counsel
women about concerns regarding potential adverse health effects during the perinatal period. There is insufcient data to evaluate the effects of marijuana use on
infants during breastfeeding, hence, marijuana consumption also during breastfeeding should be discouraged (ACOG 2017; National Council of State Boards of
Nursing 2018). Furthermore, clinicians should be discouraged from prescribing or
recommending the use of marijuana for medical purposes during the period before
pregnancy and during pregnancy and lactation. Further high-quality studies regarding the effects of marijuana and other cannabis-containing products on pregnancy
and breastfeeding are needed, including indications about the exposure and prescription to medical cannabis during pregnancy and postpartum period.
The use of cannabidiol (CBD) is becoming increasingly popular and is being
marketed for various mental conditions. Non-approved Food and Drug
Administration (FDA) commercial CBD products are available over-the-counter but
may signicantly differ in composition from those used in clinical studies for medical use. CBD is one of many chemical compounds, together with Δ9-THC, found in
the cannabis plant. The FDA has approved one cannabis-derived (CBD) drug product (Epidiolex) for the treatment of two forms of severe epilepsy and three THCrelated drug products for the treatment of nausea and vomiting caused by cancer
chemotherapy or weight loss/poor appetite in patients affected with AIDS.These
medications are only available with a prescription from a licensed healthcare provider. There is no data on CBD exposure during pregnancy and breastfeeding;
hence, CBD use should be avoided in these populations. FDA did not approve the
use of CBD products for managing nausea and vomiting or ‘gravidarum hyperemesis’, hence, CBD should not be prescribed or recommended to pregnant women
(ACOG 2017; FDA 2019).
The current urging increase in the dissemination and consumption of pseudocannabis-like products, such as synthetic cannabimimetics, ‘Spice’ drugs, Synthetic
Cannabinoids (SCBs) pose a further public and clinical concern (for a comprehensive review, see Orsolini etal. 2017). Blends falling under the brand ‘Spice’ are
composed of herbals mixed/sprayed with cannabimimetics, with some of them

22 Substance Use Disorders
473
possessing extremely high potency levels compared to traditional cannabis. The use
of SCBs has become more popular due to their increased availability and the fact
that they are undetectable in routine drug screenings. However, SCBs are more toxic
and harmful compared to natural Δ9-tetrahydrocannabinol (Δ9-THC) due to differences in activity, chemical structure, and concentration in commercial products
(Schifano etal. 2015). Research conducted by a Texas-based international team
revealed a signicant decrease in foetal brain vessel diameter and area density, indicating that acute prenatal SCB exposure causes signicant brain vasoconstriction
during critical brain development stages (Raghunathan et al. 2019). However,
adverse effects due to perinatal SCB exposure are still unknown, as analytical data
are scarce (Carlier etal. 2020). Hence, due to limited data, clinicians should recommend caution and suggest to avoid SCB consumption during pregnancy and postpartum period to all women in their reproductive age.
22.4 Stimulant Use During thePerinatal Period
Stimulant drugs, including cocaine, ecstasy, methamphetamines and prescription
stimulants, represent the second most widely used and abused class of substances,
with a lifetime prevalence among adults of around 30% (EMCDDA 2024).
Psychostimulants (‘uppers’) refer to any drug able to increase activity of the central
nervous system or those with sympathomimetic properties. Psychostimulants are
prescribed also for medical purposes, including mood disorders, impulse control
disorders such as Attention Decit and Hyperactivity Disorder (ADHD), sleep disorders and obesity (Schifano etal. 2015). Stimulants are usually misused and/or
abused due to their recreational euphoric and disinhibiting effect as well as for their
performance-enhancing purposes (Schifano etal. 2016). Women appeared to be
disproportionately vulnerable to developing stimulant misuse and abuse due to factors related to hormonal proles and reinforcement of gender constructs, as well as
in progressing to an addiction faster than men (Roth etal. 2004; Miller etal. 2015).
Epidemiological data reported a stimulant use among pregnant women in a consistent increasing trend over the last decade (Smid etal. 2019).
In the late 1980s and early 1990s, cocaine dependence was labelled an epidemic
by the US government, with 30% of young adult women reporting recent use
(SAMHSA 2007). Cocaine use during pregnancy received considerable media
attention, when photographers documented the rst newborns exposed to crack/
cocaine in utero (the ‘crack babies’ phenomenon; Chavkin 2001). Cocaine use is
associated in around 10% with women in their reproductive age, who also use opioids for non-medical purposes (Jarlenski etal. 2017). In 2015, cocaine represented
the second most common illicit substance used by pregnant women, with 3.4% of
pregnant women having used cocaine in the past month (Smid et al. 2019).
Sociodemographic associated risk factors are older age, African-American ethnicity
and low socioeconomic status (Day etal. 1993). Moreover, cocaine represents the
leading cause of ante-partum hospitalizations for substance use among pregnant
women (Cox etal. 2008). Cocaine acts on the central nervous system primarily by

474
L. Orsolini et al.
the inhibition of dopaminergic reuptake, and through the activation of noradrenergic
and serotoninergic sites in the basal forebrain and cerebral cortex (Malanga and
Kosofsky 1999). In preclinical studies, exposure to cocaine during gestation has
been shown to affect brain function, particularly the dopaminergic systems, causing
anatomical, physiological, and behavioural changes. However, human studies often
reported only mild alterations in attention, language, and memory inuenced by
environmental factors such as socioeconomic status and other drug use (Betancourt
etal. 2011). Neurotoxic effects of in utero cocaine exposure can manifest in foetal
and long-term growth outcomes, as well as structural abnormalities, determining an
impaired neurodevelopment. Maternal complications following in utero cocaine
exposure include cardiovascular complications (e.g., hypertension, myocardial
infarction, ischaemia), renal failure, hepatic rupture, cerebral haemorrhage/ischaemia/infarction and maternal death (Smid etal. 2019). Evidence supports that cardiovascular complications are not dose-dependent, by underlining that also small
doses may lead to cardiac morbidity and mortality in healthy pregnant women.
Moreover, clinicians should also consider that pregnancy may increase cardiovascular toxicity due to an increased cardiac muscle’s sensitivity to cocaine through an
increased progesterone concentration (Plessinger and Woods Jr. 1991). Cocaine
toxicity may cause severe hypertension, hyperreexia, oedema, seizures and proteinuria in pregnant women (Smid etal. 2019). A systematic review and metaanalysis conducted by Gouin etal. (2011) on 31 studies reported an increased risk
for preterm delivery, low birth weight, small for gestational age infants, earlier gestational age at delivery and reduced birth weight. Postpartum psychological distress
experienced by mothers with prenatal cocaine exposure was greater compared to
mothers not using cocaine (Smid etal. 2019). The long-term effects on child growth
and development are uncertain, though some research indicates slower growth in
children up to age 10. Cocaine exposure is linked to neurodevelopmental issues like
cognitive impairments, behavioural problems (e.g., ADHD), and language delays.
However, sociodemographic and environmental factors may contribute as much, or
more, to these outcomes. Protective factors, such as family support and better socioeconomic status, can help mitigate the negative effects of prenatal cocaine exposure
(Cressman etal. 2014). Higher rates of psychopathological symptoms (e.g., depression, anxiety, psychosis and paranoia) amongst cocaine-using women were reported
by Singer etal. (2000) which were associated with higher levels of reduced head
circumference and birthweight. A dose-response correlation between a prenatal
cocaine exposure and a lower height and weight-for-height z scores at 6years was
reported by Minnes etal. (2005). Several large longitudinal prospective cohort studies reported stable negative effects on language skills in cocaine-exposed infants
and children up to 7years of age, beyond the effect of the home environment or
other confounding factors (Singer etal. 2001; Morrow etal. 2003; Bandstra etal.
2004). Other studies on language development showed mixed ndings. In fact,
whilst gestational cocaine exposure may not cause the severe decits once feared, it
may still result in subtle cognitive impairments that could affect academic and work
performance later in life. Since brain maturation continues into adulthood, the full
impact may only become evident in adolescence or adulthood, making further

22 Substance Use Disorders
475
research necessary to understand its long-term effects (Betancourt etal. 2011). The
extent of these negative consequences depends on the dosage, timing, and duration
of a mother’s cocaine use, and therefore on how long the baby was exposed to the
drug (American Addiction Centre 2024).
Methamphetamine ([2S]-N-methyl-1-phenyl-propan-2-amine; aka ‘meth’, ‘ice’,
‘crystal meth’, ‘crank’) is the methylated derivative of dextroamphetamine, its use
had signicantly increased over the past two decades. Between 2010 and 2014, the
rate of methamphetamine-related overdoses doubled. In 2015, 1.7 million people
(0.6% of the population) used methamphetamine in the past year, with over half
(52.7%) having used it in the past month (Smid etal. 2019). Ecstasy (MDMA, i.e.,
3,4-methylenedioxy-N-methylamphetamine; aka ‘molly’) is an amphetamine-type
substance commonly consumed by younger populations, including women of
reproductive age (Center for Behavioral Health Statistics and Quality. Results from
the 2015 National Survey on Drug Use and Health: Detailed Tables. Substance
Abuse and Mental Health Services Administration 2016). Although MDMA and
methamphetamines are the most commonly abused drugs in party/rave settings, it
has been supposed that such parties would be less likely joined by women once
pregnant. Conversely, one would argue that it would be more likely to be exposed to
unwanted pregnancy in those women with risky behaviour due to MDMA-related
disinhibiting and pro-social effect. The DAISY (Drugs and Infancy) study documented a trend in both MDMA and methamphetamine use particularly in the rst
trimester of pregnancy among those women who declared a pre-conception use
(respectively, in 35% and 9% of cases); conversely, the persistence of this consumption declined throughout the pregnancy, with only 4% who conrmed its use also in
the second and third trimester (Moore etal. 2009). The DAISY study observed as
well that those pregnant women who declared a stimulant intake during the rst
trimester usually also took concomitantly cannabis, tobacco and alcohol, with one
third of them having persisted in cannabis intake throughout the pregnancy period
(Moore etal. 2009).
Methamphetamine is a central nervous system stimulant which acts by increasing presynaptic release of dopamine, serotonin and norepinephrine.
Methamphetamine use determines intense euphoria and increased levels of energy.
It can be snorted, smoked, used rectally and injected. It can be manufactured from
commonly available items such as over-the-counter cough syrups and decongestants. Methamphetamine intake has been associated with an increased risk of developing myocardial infarction, hypertension, cardiomyopathy and stroke, as well as
increased risk of infection including HIV and HCV and severe dental disease (Miller
etal. 2009). Pregnant women using methamphetamine are typically younger (under
24), unemployed, and more likely to have psychiatric disorders, live in poverty, and
have a lower perceived quality of life. They also face higher risks of legal issues and
are more likely to have family and friends who use substances (Smid etal. 2019).
Methamphetamine exposure during the pregnancy has been associated with adverse
perinatal outcomes including stillbirth, small for gestational age, preterm delivery,
caesarean delivery, and maternal intensive care unit admission, despite most studies
not having controlled the effect of potential confounding factors (e.g., maternal

476
L. Orsolini et al.
co-morbidities, tobacco smoking, other drugs, contaminants in non-pharmaceutical
preparations and poverty; Smid et al. 2019). A comprehensive meta-analysis,
including eight studies, found that methamphetamine use during pregnancy was
associated with earlier gestational age at delivery, low birthweight and small head
circumference (Kalaitzopoulos etal. 2018). Congenital malformations reported following in utero methamphetamine use included cardiac malformations, gastroschisis, limb reduction, biliary atresia and neural tube defects, despite prospective
studies having failed to conrm a causal association, except for cleft palate (Smid
etal. 2019). Newborns exposed to methamphetamine during pregnancy reported
jitteriness, drowsiness and respiratory distress at a level in need of monitoring
within intensive neonatal care units (Oro and Dixon 1987; Smith etal. 2003). An
analysis of neurobehavior at birth revealed that methamphetamine-exposed infants
demonstrated poor movement quality and high levels of physiological stress (Smith
etal. 2003; LaGasse etal. 2012). Moreover, infants with a history of heavy methamphetamine exposure showed lower arousal and reduced excitability levels compared to non-exposed infants (Wouldes et al. 2023). Furthermore, although
methamphetamine is neurotoxic, studies investigating the effect of methamphetamine exposure during pregnancy on the foetal brain are mostly pre-clinical and
overall suggesting a gestational age-dependent effect with exposure in early to midtrimester; there are concerns relating to the long-lasting effects on the serotonergic
development of the foetal brain (Won etal. 2001, 2002). Prenatal methamphetamine
exposure negatively affects brain development, particularly during early to midtrimester, leading to long-lasting neurotoxic effects. Studies show smaller brain volumes and altered metabolism in methamphetamine-exposed children, but results are
inuenced by concurrent alcohol and tobacco use (Jablonski etal. 2016; Chang
etal. 2004). Similarly, long-term studies of children exposed to methamphetamine
are limited. The Infant Development, Environment and Lifestyle study (IDEAL)
followed 412 maternal-child pairs (204 methamphetamine exposed vs 208 unexposed pairs) from the U.S.A. and New Zealand, from delivery throughout childhood; they reported increased likelihood of admission to the neonatal intensive care
unit, decreased arousal and increased physiological stress among exposed neonates
at 1month (Kiblawi etal. 2014). Heavy (e.g., more than 3days a week) prenatal
methamphetamine exposure was associated with anxiety, depression and attention
problems by age 3- and 5-years-old after controlling for other substances and caregiver/environmental risk factors (Derauf et al. 2012; LaGasse et al. 2012).
Conversely, children exposed to methamphetamine at age 7 displayed poorer cognitive functioning compared to unexposed (Diaz etal. 2014).
MDMA is a powerful monoaminergic agonist which inhibits the reuptake and
promotes the release of serotonin and, to a lesser extent, of dopamine. A chronic
maternal MDMA intake may impair memory functioning, frontal executive processing, problem solving, decision making and social and emotional intelligence;
these issues may be the result of altered parental style, newborn/child-focused attention, communication and attachment style, and cognitive impairment (Rodgers
2000; Rodgers etal. 2003; Fisk etal. 2005; Rendell etal. 2007). Pregnant women
who use MDMA during pregnancy are more likely to suffer negative consequences,

including work- and social-related impairment (Singer etal. 2012). There is limited
data on foetuses and infants of women exposed to MDMA during pregnancy. Most
data come from animal studies which documented an increased mortality, retinal
eye defects, cleft palate, rib malformations, decreased physical growth and delayed
motor development. There are only isolated reports of cardiac defects, cleft lip and
biliary atresia after amphetamine in utero exposure in human infants, a reduced
growth and increased foetal distress (Eriksson etal. 1978, 1981; Billing etal. 1980;
Dixon and Bejar 1989; Catanzarite and Stein 1995; Plessinger 1998). Using MDMA
during pregnancy can harm both the mother and the baby. In a single-centre study,
pregnant women using methamphetamine were more likely to experience pre-term
delivery, caesarean section and maternal ICU admission. However, the study did not
consider other factors such as smoking, other drug use, or socioeconomic status
(Good etal. 2010). Pregnant women who use MDMA are more likely to display
higher rates of unplanned pregnancies, therapeutic abortions, binge drinking, smoking and using other drugs. The drug can also negatively affect the mother’s health,
causing stress, high body temperature, appetite loss, sadness and sleep disturbances
(American Addiction Center 2024). Babies exposed to ecstasy in utero may face
increased risks of congenital defects (cleft palate, gastroschisis, biliary atresia, and
neural tube defects), cardiovascular (cardiac defects) and musculoskeletal issues
(limb reduction), low birth weight, smaller head circumference at birth, motor
delays, and developmental problems (Landry 2002). However, prospective studies
have not consistently found such associations, except for cleft palate. Infants
exposed to methamphetamines may experience amphetamine withdrawal syndrome
with symptoms like jitteriness, drowsiness, and respiratory distress, though only a
few need a pharmacological treatment (Smid etal. 2019). MDMA exposure in the
rst trimester can lead to long-term memory and learning issues in children.
22.5 Opioids/Opiates inthePerinatal Period
A large cohort study involving pregnant women who use prescription opioids
reported a 30–60% increase in the risk of neonatal drug withdrawal associated with
co-exposure to other psychotropic drugs compared with opioids alone (Huybrechts
etal. 2017). A chronic untreated addiction to heroin in pregnancy has been associated with lack of prenatal care, increased risk of foetal growth restriction, abruptio
placentae, foetal death, preterm labour, and intrauterine passage of meconium
(CSAT 2005). Babies born from heroin-dependent mothers often present with a
neonatal abstinence syndrome, which manifests as restlessness, yawning, acute crying, tremors, watery stools, hypertonia, seizures and vomiting. There is also a risk
of sudden unexplained death in infancy (Dryden etal. 2009; Wachman etal. 2011;
Hwang etal. 2016; Huybrechts et al. 2017; Flannagan etal. 2020; Varney et al.
2024). According to some studies, naloxone, a specic opioid antagonist, could be
used to treat infants with cardiorespiratory or neurological depression due to intrauterine opioid exposure. However, current evidence from randomized controlled
trials is insufcient to determine whether naloxone provides signicant benets

L. Orsolini et al.
given some concerns about its safety (Moe-Byrne etal. 2018). Moreover, rates of
unwanted pregnancy among women using opioids are remarkably high, with
unwanted pregnancies reported in 85% of women using opioids during pregnancy,
compared to 45% of the general population (Auerbach etal. 2021). Furthermore, an
untreated opioid use disorder has been associated with engagement in high-risk
activities, such as prostitution, trading sex for drugs, and criminal activities. Longterm outcomes of infants with in utero opioid exposure have been evaluated in several observational studies, reporting no signicant differences in cognitive
development between children up to 5years of age exposed to methadone in utero
and control groups matched for age, race and socioeconomic status, although scores
were often lower in both groups compared with general population (Kaltenbach and
Finnegan 1984).
The safety of opioids during early pregnancy has been evaluated in several observational studies. Earlier reports have not shown an increased risk of birth defects
after prenatal exposure to oxycodone, meperidine and propoxyphene (Bracken and
Holford 1981; Jick et al. 1981). An association between rst-trimester use of
codeine and congenital abnormalities has been reported in some studies (Zierler and
Rothman 1985; Broussard etal. 2011) but not in others (Shaw etal. 1992; Nezvalova-
Henriksen etal. 2011). An observational study found a possible association between
use of opioids during the rst trimester and neural tube defects (Yazdy etal. 2013;
Wang etal. 2022). Some studies have also identied a link between prenatal opioid
exposure and birth defects, albeit rare, such as congenital heart defects, cleft palate
and clubfoot (Yazdy etal. 2013; Källén etal. 2013; Lind etal. 2017; Wang etal.
2022). Developmental delays in children exposed to opioids are possible compared
to their non-exposed peers (Welton etal. 2019).
In contrast, recent studies have shown that tapering the dosage, or carrying out
an opioid detoxication, does not increase the risk of adverse pregnancy outcomes,
resulting in neither an increased foetal risk associated with detoxication nor an
increased risk of preterm delivery (Towers etal. 2020). Comparing detoxication
treatment with opioid substitution therapy (ORT) shows an increased risk of relapse
with detoxication treatment compared to ORT; however, detoxication does not
alter the risk of stillbirth, preterm birth (PTB) nor neonatal abstinence syndrome
(NAS) (Wang etal. 2019). Methadone is commonly used as an opioid agonist medication, providing stability of opioid levels, preventing withdrawal cycles, and
improving engagement with obstetric care. However, its use is limited by stringent
observation protocols and the risk of overdose. Children born to mothers who were
prescribed with methadone during pregnancy have a high risk for behavioural problems, poor motor performance, poor ne motor coordination, short attention span,
and low cognitive performance. Nystagmus and strabismus are more frequent in
methadone-exposed children than in non-methadone-exposed peers (Monnelly
etal. 2019). Another alternative to methadone is buprenorphine. As a partial opioid
receptor agonist, it has a limiting effect on respiratory depression, reducing the risk
of harm in the event of an overdose. It also offers a more favourable neonatal opioid
withdrawal prole than methadone and has been associated with more positive neonatal outcomes than methadone. These include better levels of birth weight, longer

22 Substance Use Disorders
body length at birth, and reduced risk of prematurity (Kinsella etal. 2022). Pregnant
women receiving treatment for opioid use disorder with the buprenorphine- naloxone
combination have comparable pregnancy outcomes to those undergoing treatment
with other forms of opioid agonist medication-assisted therapy (Link etal. 2020;
Ordean and Tubman-Broeren 2023).
Fentanyl, a highly potent synthetic opioid commonly used in patients undergoing
general anaesthesia, including women undergoing various surgical procedures during pregnancy and for epidural analgesia during labour, rapidly transfers to the placenta and foetal brain, with detectable accumulation in these tissues (British
Columbia Centre on Substance Use 2018; Alipio et al. 2021). Studies in animals
suggest prenatal fentanyl exposure may lead to increased newborn mortality, withdrawal symptoms, ADHD, autism-like traits and schizophrenia. These ndings
highlight the complex risks of opioid exposure during pregnancy, particularly with
potent opioids like fentanyl (Wouldes etal. 2023).

22.6 Pharmacological Management ofSubstance Use
Disorders During thePerinatal Period
In general, substance-dependent pregnant women should be optimally treated with
a multi-disciplinary and multi-professional approach with treatment being tailored
individually to the kind of substance dependence (Woolf etal. 2003; Metz et al.
2012; WHO 2014) (Table22.1).
There are no ofcially approved pharmacological treatments for the management of a cannabis use disorder in pregnancy. No medication is approved specically for the treatment of cannabis intoxication. Pregnant women could usually
manifest mild cannabis withdrawal symptoms including sleep disturbances, irritability, loss of appetite, restlessness, nausea and cramps which could be managed by
prescribing symptomatic pharmacotherapy (Rayburn and Bogenschutz 2004;
CAMH 2012). Evidence advice for all pregnant women is to discontinue cannabis
use, although for some women this may not be possible without professional support. Pharmacological interventions for cannabis withdrawal have been explored,
though studies often have small sample sizes (Connor etal. 2022). Some trials using
standardized withdrawal scoring systems reported better symptom relief with medications compared to placebo. Effective treatments include dronabinol (Levin etal.
2011), quetiapine (Mariani etal. 2021), nabiximols (Trigo etal. 2016), gabapentin
(Mason etal. 2012), and oral THC (Budney etal. 2007), which reduced withdrawal
symptoms and cravings in cannabis-dependent individuals. To date, dronabinol has
been the medication most investigated. Dronabinol has been assigned by the Food
and Drug Administration (FDA) to pregnancy category C, i.e., animal studies have
revealed evidence of decreased maternal weight gain and decreased number of offspring, increased foetal mortality, and early foetal resorptions. Exposure to dronabinol during pregnancy and lactation in mice caused anxiety-like and depressive
behaviours, cognitive impairments, and disruptions in the reward system, with
increased motivation for alcohol consumption in offspring. These effects, linked to
