i've been smoking pot chronically for 7 years, and some people have been smoking pot chronically for 20, 30 years. Nothing is wrong with me, I smoke every single day that goes by, taking the biggest hits i can, holding them in for as long as my lungs will let me...and i'm still functioning totally normal

plenty of people know a lot about long term usage of pot. it's not a new drug or anything, wtf?
