Cocaine is a highly addictive stimulant that is put into the body in three common ways: smoking, sniffing, and/or injection. It gives users a feeling of extreme pleasure, but it lasts only a short amount of time. If cocaine is smoked (known as crack cocaine) the high is almost immediate but only lasts about 5 or 10 minutes; if it is snorted, the high may not occur as rapidly, but will most likely last longer, about 15-30 minutes.
Cocaine is a very addictive substance and the high is only short-lived, so when the high ends, users continue to go back for more. They may experience a crash after their high has ended and this only helps to feed the addiction. The risks and side effects are very serious and often times using leads to serious addictions.
