Well, didn’t really want to get into a #'s game BUT:
I make some good cash for a 22 year old, and I could be considered a “pot head”.
Have another friend who smokes probably 3-7 times a week, he makes about $10k/month, and he’s 21.
Have another buddy who’s going nowhere in life, smokes daily.
Have another body working 2 jobs, one paying $30k/year salary, the other is about $1.5k/month (server @ restaurant).
Know a pothead who sits on a couch all day playing video games, with zero income, zero car, zero value for his own health, you name it.
THE BOTTOM LINE IS POT HAS NOTHING TO DO WITH YOUR INCOME. Your income, and your “successfullness” (in the eyes of others) has nothing to do with smoking pot, and EVERYTHING to do with who you are.
Some people can handle it, others can not.
