Marijuana:
Common slang names: pot, weed, grass and reefer
What happens when a pregnant woman smokes marijuana? Marijuana crosses the placenta to your baby. Marijuana, like cigarette smoke, contains toxins that keep your baby from getting the proper supply of oxygen that he or she needs to grow.
How can marijuana affect the unborn baby? Studies of marijuana in pregnancy are inconclusive because many women who smoke marijuana also use tobacco and alcohol. Smoking marijuana increases the levels of carbon monoxide and carbon dioxide in the blood, which reduces the oxygen supply to the baby. Smoking marijuana during pregnancy can increase the chance of miscarriage, low birth-weight, premature births, developmental delays, and behavioral and learning problems.
What if I smoked marijuana before I knew I was pregnant ?According to Dr. Richard S. Abram, author of Will it Hurt the Baby, "occasional use of marijuana during the first trimester is unlikely to cause birth defects." Once you are aware you are pregnant, you should stop smoking. Doing this will decrease the chance of harming your baby.
PCP & LSD:
What happens when a pregnant woman takes PCP and LSD? PCP and LSD are hallucinogens. Both PCP and LSD users can behave violently, which may harm to the baby if the mother hurts herself.
How can PCP and LSD affect my unborn baby? PCP use during pregnancy can lead to low birth weight, poor muscle control, brain damage, and withdrawal syndrome if used frequently. Withdrawal symptoms include lethargy, alternating with tremors. LSD can lead to birth defects if used frequently.
What if I experimented with LSD or PCP before I knew I was pregnant? No conclusive studies have been done on one time use effects of these drugs on the fetus. It is best not to experiment if you are trying to get pregnant or think you might be pregnant.
