A lot of people experiment with drugs just for the experience not to 'escape their problems.' I had absolutley no problems when I experimented with drugs. I just wanted the see what it was all about. Addicts are a different story. And they will be an addict with almost anything, drugs, tobacco, alchohol, food, abuse, religion etc. That's the addictive personality. They need it to fill a void. Most people who have used drugs are normal everyday people. Those who smoke pot are no different then those who drink. It's a natural herb, it has medicinal purposes, it's not addicting and so on. Tobacco kills more people than almost anything else. Why is that legal? Personally, I think people who are judgemental about what others do in their private lives are pathetic.
PS
I'll bet anything McCartney still smokes some weed every now and then. So I guess he's a pathetic loser too.
