Addiction has an important biological component, but it is obvious that what happens in the development of addiction is not just the issue of neurodaptation.

Anyway, drugs help people to break down barriers of defense, shyness and so on. We have psychological and also group aspects. Using cocaine, alcohol and even marijuana has to do with a tribal, ritualistic relationship of young people. In fact, addiction is a combination of factors. It develops through biological, psychological and cultural factors. Addiction is a combination of biological, psychological and cultural factors.
