Most of the abused drugs target the brain’s reward system directly or indirectly, by flooding the brain circuits with dopamine which is a neurotransmitter present in different regions of the brain. This neurotransmitter regulates emotion, cognition, movement, motivation and even feelings of pleasure. When a drug enters the brain, it can change the performance of the brain in accomplishing its jobs. These changes can lead to compulsive drug use which can turn into an addiction.

Drug abuse can lead to various behavioral problems such as paranoia, hallucinations, addiction, loss of self-control, impaired judgment, impulsiveness, etc.
