Drogas peligrosas: cocaína

Cocaine, derived from coca leaves, is found in powder and stone forms. It is often mixed with other substances, reducing its purity to 15-20%. As a stimulant, cocaine increases dopamine production, leading to short-lived pleasure but long-term harm and addiction. Users may feel overconfident and take dangerous risks. Cocaine alters brain chemistry, causing dependency. It raises body temperature and heart rate, leading to increased alertness but also dangerous health risks like high blood pressure, heart attacks, and potential overdose consequences such as seizures and heart failure.
