Stimulants
QUICK FACTS
The most common stimulants are Cocaine, Methamphetamine (Meth), and Amphetamine (ADHD medication known commonly as Adderall)
Cocaine, Meth, and Amphetamine cross the placenta
Cocaine causes vasoconstriction (narrowing of blood vessels) which can cause problems associated with poor blood flow1
POSSIBLE RISKS
Cocaine:
Growth Related Issues2:
Small for gestational age (measures small during pregnancy)
Reduced birth weight (measures small at birth)
Shorter gestational age at delivery (earlier birth than the average)
Preterm birth (born before 37 weeks)
Neurobehavioral effects3,4 (brain and behavior symptoms) may occur within the first 3 days of life. These are likely transient and do not show long term effects.
Tremors/jitteriness
High pitched cry
Irritability
Excessive suck
Vital sign changes (blood pressure, heart rate, respiratory rate)
Other rare risks may include miscarriage, placental abruption, and small intestinal atresia (poor formation of the small intestine)
Amphetamine and Methamphetamine:
Growth related issues5-8:
Fetal growth restriction
Preterm birth
Reduced birth weight
Smaller head circumference
Small for gestational age
Pregnancy and Birth risks:
Preeclampsia
Placental abruption
Neonatal and Infant death9
Risk of cognitive problems is unclear.
WHAT TO LOOK FOR
Cocaine:
Look for signs of growth restriction
Size
Weight
Head circumference
Look for signs of neurobehavioral problems within the first 3 days of life:
Tremors/jitteriness
High pitched cry
Irritability
Excessive suck
Vital sign changes (blood pressure, heart rate, respiratory rate)
Look for long term cognitive problems:
Risk for long term cognitive and behavioral issues is unclear. Some studies show no evidence for cognitive and behavioral issues while some show10,11:
Attention deficits
Behavioral self regulation (self control) deficits
Some minimal language and cognitive delays
Minor processing and executive function deficits
Amphetamines:
Look for signs of growth restriction
Size
Weight
Head circumference
Look for long term cognitive problems:
Risk of cognitive problems is unclear. Some studies show no evidence for cognitive problems while others show12,13:
Learning and memory difficulty
Motor delays (movement/muscle tone)
Brain structure changes
Attention deficits
WHAT TO DO
Watch for any growth related delays and seek appropriate medical treatment and/or therapy as early as detected.
Watch for any behavioral problems as listed above and seek early intervention.
Talk to your pediatrician about any concerns you may have about your child’s health and development including social and behavioral concerns.
