When I smoked for the first time, it was with my cousin and his friend .Nobody told me that I wasn't supposed to inhale the smoke.Then the next couple of people I smoked with didn’t inform me that I wasn't supposed to inhale the smoke .So,for the first year of smoking, I was inhaling each and every toke.Until one night at a friend's house, she had another girl visiting and we were smoking and I guess she saw that I inhaled the smoke and said " Don't ever inhale, it can fuck your lungs up !" .No telling what kind of damage I have already caused.But ,I thought to myself " Nobody ever bothered to share that important piece of information with me ".Sometimes, I catch myself beginning to inhale and remember I'm not supposed to. Anybody else that just had to learn as you go along ?
