i smoke both cigarettes and marijuana... i do admit i am addicted to cigarettes and recently i had just started to feel the bad consequences (FYI i was well aware of whats to happen) before i got into the "YOSI" thing, i was only an occasional smoker (only smoking at special occasions, parties, and such). but i got addicted only when i worked as a IT tech support ojt student at some call center... and the result, uber pressure from all the agents smoking to relieve stress at work... and in the long run, i myself enjoyed chit chats with them while smoking.... and as for marijuana, well im still just occasional on this. a puff or two just sets you in the right mood to relax and unwind a bit... and i've only been into a few hand counted sessions... i am not planning to let this ruin my life lol... there ya go... my two cents worth...
