Ahhh winnie,
Just a note, with our sons because of their ages. My son can't understand how he can be an addict when all his friends are doing the same thing. The difference in their use is not the same, his friends are what I would call recreational, they do it on the weekends, where as our sons want the fix everyday, all day. Because of their age I can totally understand that they don't get it, or understand why they are different, then their friends....heck who wants to be different.
Just my thoughts on drug abuse, would be abusing a drug that is not addictive, this could be prescription or non prescription. Example: Taking Phentermine (Not addictive, but can be habit forming) for dieting instead of taking the one pill daily, taking more for the speed effects.
