Using psychoactive drugs, be it to find pleasure or to avoid pain, can harm health and cause social problems both in the short and longer term.
Psychoactive drugs affect communication between brain cells in certain regions of the brain. For instance, some drugs mimic and others block the effects of naturally occurring molecules that carry specific messages from one brain cell to another.
Drug addiction is more common among people with mental disorders than among the general population. For example, people with mental disorders are more likely to be alcohol dependent at some stage in their lives than people without a mental illness.
