Yes, it is harmful to both the mother and the child, and in fact, most women who are abusing cocaine are at the age where they can have children. There have been studies that suggest around 2 to 5 percent of women who are pregnant use more than one type of addictive substances, and there are hundreds of thousands of cocaine-exposed pregnancies each year. There are numerous specific risks associated with using cocaine during pregnancy for both the mother and child. When women use cocaine in any fashion during pregnancy, they will experience seizures, maternal migraines, premature membrane rupture, and the separation of the placental lining from the uterus prior to the delivery of the baby. The use of cocaine during pregnancy will also increase the woman's blood pressure, which could lead to a miscarriage.
Unfortunately, most babies born to mothers who have been using cocaine are premature and have very low birth weights. This also includes the risk of the child having reduced intelligence, brain damage, and future health complications. Any woman who is pregnant and using drugs such as cocaine should find help immediately, whether it is through the local hospital or a drug treatment program. There are specific types of drug and alcohol rehabilitation services for pregnant women, and these programs are typically residential centers and have the capability to monitor and work with a woman who is pregnant and addicted to drugs.
