Cocaine

Cocaine is a powerful stimulant drug derived from the leaves of the coca plant. It affects the brain by increasing levels of dopamine, a neurotransmitter associated with pleasure and reward, leading to intense short-term euphoria. However, cocaine is highly addictive and can have severe health effects, including increased heart rate, anxiety, and risk of heart attack or stroke. It can be consumed in various forms, such as powder or as crack cocaine. Due to its potential for addiction and harmful consequences, cocaine use is illegal in many places and is considered a serious public health issue.
