Pathophysiology Reward Pathway

Abused drugs generally produce pleasant effects that are desired by the user. However, while most individuals will experience pleasant effects, not everyone abuses these drugs, and not everyone who abuses them becomes dependent on them. Why some persons abuse drugs while most people do not is a complex area of research. It appears that genetic, environmental, and cultural factors may all interact to predispose some individuals to substance abuse and subsequent dependence. The initial hedonic experiences secondary to use of drugs appear to be primarily due to their ability to activate the primary reward circuits in the brain. These same reward circuits operate under normal circumstances to reinforce certain activities that promote survival, such as food, social affiliation, or sexual activity.
