Are you the real Fred Durst (aka, Limp Bizkit)?

If so, I wouldn't doubt that you have a lot of friends addicted to marijuana.

In terms of a response to your post, I am less than 4 months away from turning 30 years old. All of my friends were "potheads" in high school (and college). Zero of them had their life destroyed by it. They are all productive, upstanding people. If anything, I think the fact that some of them were stigmatized so heavily by being potheads really set them back.

Now, this is just anecdotal and I may not represent a "representative sample". So that's just my experience.
