Cocaine is one of the most powerfully addictive drugs. It has a stimulant effect on the brain that is immediate: a sense of euphoria, a numbing of the senses, and drastic changes to the central nervous system. This causes a variety of behavioral changes and mental delusions. Cocaine can cause heart attacks, strokes, and seizures, and in some rare cases, sudden death on the first use. It is a Schedule II drug, which means it has a high potential for abuse but can be administered by a doctor in certain medical instances¹. Crack is a very dangerous type of cocaine that is smoked. Crack is extremely addictive and can cause major organs to stop performing their normal functions.
