We all deal with our problems differently, and sometimes people just break down when faced with difficult problems. Some seek help, while others deal with it a different way: through drug abuse. I know, it seems so common nowadays, but it is a reality. There are lots of drug rehab center out there, but sometimes there are relapses. I do believe that since it is a personal problem, then the treatment differs with each person. I mean, one treatment could work for a hundred persons, but it might not work with one. Or at least that's what I understood from an infofact about the treatment of drug addiction.
For sure, different people have different opinions about drug addiction and it's treatment. I believe that it's because it's a personal thing; different people react differently to different stimuli. But, am not an expert on this. Just a personal opinion. :P
