kaetic has a really good point, and so do the others really. I would never recommend smoking to anyone, it can make you dull and such.
but I do smoke, not as regularly as I use to, but i still do. I recommend not smoking everyday, and never spark up before class or work, only when you got nothing better to do. Do not waste your time when you are high though, go outside with friends, have a bone fire, play music, draw. Pot is a tool to open a certain door in your mind, nothing more nothing less.
Never smoke with people you don't trust, avoid smoking alone. I think that is what i would tell my kids if they smoked... But obviously the best solution is not to do it, it is a trap, i have lost friends to it, brilliant minds turned to stuttering fools.
Peace out bro!
