Marijuana is obviously much better to be dependant on than alchohol. Alchohol is one of the hardest drugs out there.
Wish I could get my dad on that program, he's not really an alchoholic, because it doesn't affect his life negatively, but he drinks way too much and I worry about his health, him being almost 60 and all.
I'd love for my dad to spend his golden years puffing on a joint with me and my brothers, who all smoke, than see him drink more beer.
Hope you can help your uncle out, with any luck he'll be thanking you in the years to come
Keep blazing
