I was just reading a news a few minutes ago about a husband randomly murdered on the street. It sounds horrible but upon reading closely, it seems that the husband had been on drugs for many years now.. possibly over ten years ago.
The drug world is a scary world. I personally have no experience over it and don't really have any friends that directly deals with it but I personally don't think TV shows and movies exaggerate too much on this issue.
Drugs can really kill if one goes overboard. So please think about admitting yourself into inpatient drug rehab if you find yourself with drug problems. When something happens to you, its your family that suffers the most, not you.
