There was a talk show going on the radio while I was driving to work. They were discussing about drug addicts. They had a psychologist on the talk show.
The Dr shared that most of his patients have been in and out of drug rehab for more than 2 times.
It is sad, but he said a lot of his patients fall back to their old ways, once they reenter the society. It may be due to peer pressure and society pressure. But some actually preferred to stay at the rehab where the environment is controlled and they are well taken cared off.
