Pregnancy-Related Issues in the Management of Addictions
Overview of Addictions
Key Concepts
Addiction (dependence)
Women using addictive substances find the
effects of the drug so pleasurable and
reinforcing that they have difficulty controlling
their use of the drug
Reinforcement may be small and multiple, e.g.,
nicotine, or large, e.g., heroin
Many Substance Users are
Survivors of Childhood Trauma
Women in substance abuse treatment report:
A lifetime history of trauma, most commonly
physical or sexual abuse
This ranges from 55% to 99% compared to
women in community samples (36-51%)
Najavits et al, 1997
Addictive Potential of Drugs
Correlates with:
Rapid onset of action
Potency at receptor site (euphoric effect)
Short duration of action (contrast between intoxication
and sober state)
Tolerance (forces woman to escalate dose to achieve
same effect)
Withdrawal (forces woman to use drugs to avoid
withdrawal)
Reward Pathway
All drugs of abuse:
Increased dopamine receptor stimulation in
nucleus accumbens and medial forebrain bundle
Cocaine stimulates it directly
Opioids, alcohol, nicotine stimulate it via effects
on other neurotransmitters
Opiate Use is a Very Powerful selfmedication for:
Blocking out intrusive thoughts, flashbacks
and nightmares
Numbing and avoiding feelings, thoughts,
people
Achieving sleep
Tolerance
Repeated administration alters:
Receptor numbers and sensitivity
Levels of neurotransmitters
Result: decreased effect with same dose
CNS develops ‘resistance’ to drug effect
Adaptive mechanism: can function almost normally
despite very high doses
Tolerance (2)
Rate of development of tolerance depends on
the effects
For example, with opioids:
Analgesia - slow tolerance (months)
Sedation – rapid tolerance (days)
Withdrawal
On sudden cessation of drug, alterations in
receptors take days or weeks to normalize
Receptors that ‘resist’ the drug are now
unopposed, leading to drug-opposite effects:
Sedating drugs: withdrawal -> autonomic hyperactivity
Symptoms appear when drug use decreases,
forcing woman to resume drug use
Genetic Influences on
Drug Dependence
Positive family history increases risk of alcohol
dependence:
Fewer adverse effects
Greater tolerance
More positive effects
Sex and Gender Differences
The Formative Years report from CASA
demonstrates that:
Girls and young women use cigarettes, alcohol
and drugs for reasons different than boys
The signals and situations of high risk are
different
Girls are more vulnerable to substance use and
abuse and its consequences
Girls have incorrect knowledge and beliefs about
substances
Parents are often inattentive
cont’d
CASA. The Formative Years: Pathways to Substance Abuse Among Girls
and Young Women Ages 8-22. 2003. www.casacolumbia.org
Sex and Gender Differences (2)
The Formative Years report indicates that
girls are influenced by:
Substance-using friends
Schools and communities that turn a blind eye
Physicians who are not vigilant to early
warning signs
Exposure to entertainment media and alcohol
and cigarette advertising, which bombard girls
and young women with unhealthy and
unrealistic messages about smoking, drinking
and weight loss
Substance Use by Women
Substance use by women has been viewed by
health professionals as more problematic
This has led to disparities in screening and access
to care and treatment
Poor women, aboriginal women and women of
colour are more frequently screened for substance
use when accessing prenatal care than middle
class and Caucasian women
Risks for Addiction
Psychiatric Risk:
Mood disorders
Anxiety disorders, esp. post-traumatic stress disorder
Personality disorders that effect impulse control
Social, Cultural:
Lack of meaningful work/school/relationships
Lack of social support
Cultural attitudes towards alcohol, drugs
Poverty
Clinical Features
Drug use becomes major focus of life and the
addicted woman:
Neglects major responsibilities
Continues to use despite knowledge of
consequences
Repeatedly tries to quit but relapses
Develops tolerance and can go into withdrawal
Experiences powerful urges to use (cravings)
The 4 C’s of Addiction
Continued use despite Consequences
Unable to Cut down
Cravings
Compulsive drug use
Classification of Drugs of Abuse
Alcohol
Benzodiazepines and other sedatives
Opioids
Stimulants: cocaine, amphetamines
Nicotine
Cannabis
Hallucinogens
Psychological Treatment
Natural Recovery
Mutual Help Groups
Outpatient Counseling
Residential Treatment
Minnesota model (28 or 21 day)
Therapeutic community (months to years)
Treatment of Substance
Dependence: Prognosis
Approx. 30% abstinent one year post-treatment
Prognosis worse if:
Older
Longer drinking history
Other substance use
Untreated psychiatric disorder(s)
Social instability
Physician’s warning associated with better
prognosis at 2 years
Treatment is cost-effective

Treatment for Women and Mothers
When mothers and babies stay together in
treatment, women indicate that
maintaining close contact with their
children was integral to their recovery
efforts.
Besinger, B.A. 2003. Mothers in addiction treatment: The role of onsite childcare.
University of Cincinnati, Cincinnati)
Women stayed in treatment longer, had
less depression and higher measures of
self-esteem than women separated from
their infants.
Wobbie, K., & Eyler F.D., 1997. Women and Children in Residential Treatment: Outcomes for
Mothers and their Infants. Journal of Drug Issues, 27 (3), 585-607
Cost-effectiveness of Treatment:
Matched Case-control Study
300% reduction in health care costs in treated
group vs. waiting list controls
Holder HD, Blose JO. J Stud Alcohol 1992; 53: 293-302
Role of the Health Care Providers
Most substance users do not go to formal treatment
BUT they make frequent use of health care provider
(HCP) services
Women often have considerable trust in their
nurse/midwife/physician
Health Care Providers should see women over long
periods of time and build therapeutic relationships in
order to effect long-term change
cont’d
Role of Health Care Providers (2)
Smoking cessation counselling: one of the
most cost-effective interventions we can do
At-risk drinking: often brief advice (5-15
minutes) is enough to get women to reduce
drinking to low-risk levels
Alcohol and drug dependence: many women
will accept HCP advice to attend treatment
program
cont’d
Role of Health Care Providers (3)
Treatment of withdrawal is first step to recovery
Pharmacotherapy (methadone, bupropion, NRT,
etc.) greatly increases success rates of
counselling
Failure to Understand and Address
Trauma Can Lead to:
Retraumatization of the woman
Increase in symptoms
Increase in management problems
Increase in relapse
Withdrawal from service relationship
(Finkelstein, 2006)
Approach to the Woman who is
Addicted to Substance(s)
Do’s: Like any other disease…
Express concern
Review diagnosis and health effects
Present range of treatment options
Acknowledge woman’s efforts and successes
Arrange follow-up
Approach for Provider/Counselor
and Woman
Meet basic needs
Build positive social network
Advise group and individual support
Teach techniques to avoid drugs and triggers
for substance use
Encourage to have a structured day, keep busy
