Smoking –1. CO increase –Nicotine yields vasoconstriction –Tar (particular matter of smoke) »Cyanide »Lead »Global toxic elements

LSD Use –Jacobsen and Berlin (1972) –140 women used LSD prior/during pregnancy –148 pregnancies yields 83 live births –Many gross abnormalities –LSD use in first trimester yields 43% miscarriage –Of 83 live births, 8 had defects –Abortions 65 (12 spontaneous, 53 therapeutic)

Ethanol Fetal Alcohol Syndrome (FAS) –80% of normal size –Decreased intellectual functioning –Behavioral problems –Hippocampal region impact noted on animal studies –Distinctive appearance

Ethanol Distinctive appearance –Narrow eye openings –Flattened grove between upper lip and nose –Up turned nose –Thin upper lip, lack of “cupid’s bow”

Ethanol Twelve year follow-up of FAS –11 children –2 dead –4 Borderline IQ –4 Severe IQ problems

Ethanol Fetal Alcohol Effect (FAE) –Milder but still demonstrable syndrome Alcohol Related Neurological Disease (ARND) Ethanol appears to affect the development of the corpus callosum
