Marijuana can also have a serious effect on reproduction. Some studies have shown that women who smoke marijuana during pregnancy may give birth to babies with defects similar to those seen in infants born with Fetal Alcohol Syndrome - for example, low body weight and small head size. Cocaine Cocaine is one of the most powerfully addictive of the drugs of abuse, and it is a drug that can lead to death. No individual can predict whether or not he or she will become addicted or whether the next dose of cocaine will prove to be fatal. Cocaine can be snorted through the nose, smoked, or injected.
Cocaine is a very strong stimulant to the central nervous system, including the brain.
This drug produces an accelerated heart rate while at the same time constricting the blood vessels which are trying to handle the additional flow of blood. Pupils dilate and temperature and blood pressure rises. These physical changes may be accompanied by seizures, cardiac arrest, respiratory arrest, or stroke. Nasal problems, including congestion and a runny nose occur with the use of cocaine, and with prolonged use the mucous membrane of the nose may disintegrate. Heavy use of cocaine can sufficiently damage the nasal septum to cause it to collapse.
