Age 13-16, smoked about once every 2 weeks(average).
Age 16-18 DRY (locked up, couldn't smoke)
Age 18-21 basicly smoked everyday... soo...

26 (times a year) X 3 (years) = 78 Days
365 (times a year) x 3 years = 1095 Days

all together 1,173 days worth the smoking (i often smoke all day, bowl after bowl) doesn't sound like so much if you really go back and count it up....
