Cocaine is a drug made from the leaves of the coca plant, which grows in South America. It is a stimulant, which means it causes euphoria, increased physical activity, sleeplessness, and increased energy. It also raises the heart rate and blood pressure and causes more rapid breathing. In very high doses, seizures may occur. Crack, a less expensive form of cocaine, has recently become available, making cocaine abuse a widespread problem.
Pregnant women using cocaine are at high risk of miscarriage.
Babies born to cocaine-dependent mothers are addicted at birth. The infants are jittery and don't respond well to people. Moreover, they have to go through the agonizing process of withdrawal. Some people are more sensitive than others to cocaine. A small amount of the drug can kill people sensitive to it.
