The most accurate conclusion we can draw from research on the long-term effects of drug use on brain and behavior is that it tends to be harmful, but the effects can be reversed. Animal research has confirmed this. However, we cannot say that it is never harmful, and it is difficult to know exactly how harmful it is because drug users tend to use many different drugs, and animal research is rarely done to study drug abuse. It is also not accurate to say that long-term use is rarely harmful, as research has shown that it can have negative effects on the brain and behavior.
