I've had my share of pot so i can dig the comments of pro and con. Seems that the weed of nowadays is something much more powerful than say 10 or 15 years ago. I tried one of his joints a while ago and I was off the planet - not in a relax high manner, but very confused and awkward. This stuff is heavy. I would die smoking this every day, and I do regular sports, eat healthy and whatnot. I could smoke daily before because the stuff would just get you high, but the stuff he smokes is like a trip. It's like it's so strong it controls you rather that let you get high.
It is a lot stronger, but just like beer and whiskey, you don't have to consume the same volume.
If I was to smoke the modern bud in the same manner I did when I was a teen, I'd be in a coma. If you have a hit, I just take what you need and don't feel obligated to make sure the whole joint gets smoked all at once. Better yet, micro bong hit.
I seldom ever even see the stuff anymore, but if I do, I'm the one in charge of how much I take.
