What is drug addiction?

Addiction is a chronic disease that is compulsive and hard to control. The first time sone take drugs is a voluntary decision for most drug users, but repeated used after can lead to brain changes that challenge an addicted person's self control and interfere with their ability to resist intense urges to take drugs or do other things to subitize for drug uses. These brain changes can become persistent, even when a person quit using drugs they can still go back to the use of it.

Since taking drugs release dopamine a lot faster than doing other activities that actually reward you, this surge will cause your brain to continue to do unhealthy behaviors like consistently taking drugs. 

As the brain now perceive drugs a way to release dopamine, everything else you do may not feel as appealing as it should be. The brain slowly adapts to this short term gratifications and cause the person to become less able to derive pleasure from other things they once enjoyed, like food, sex, or social activities.
