i started smoking when I was 17. Pretty much a stoner from the get go. I'm 28 now. take off 4 years when I was in the military and about 2 years total from when I would stop smoking when I thought it was getting the best of me. So i guess about 5 years total. I average now about a bowl maybe two a day. I only smoke after i get home from work after the kids go to bed and on weekends I usually smoke 3 to 4 bowls a day.
