illicit drugs

Illicit drugs are substances that are illegal to produce, possess, or sell due to their potential for harm, addiction, or abuse. They often affect the brain's chemistry, altering feelings, perceptions, and behavior, which can lead to physical and mental health problems. Common examples include heroin, cocaine, methamphetamine, and illegal forms of marijuana. These drugs can cause dependence, impair judgment, and increase the risk of accidents or health complications. Laws against them aim to protect individuals and communities from their dangerous effects, but misuse or trafficking of illicit drugs remains a significant social and health challenge worldwide.
