I think you should only worry if you start going crazy without it... If not smoking doesnt make you feel depressed then you wouldn have to worry I think
i smoke once or twice a day, and i dont think i am a pothead. my friends seem to think i am, the ones that DONT smoke lol.
I definatley not addicted. I'm more of social smoker, than a total pothead (Although Everybody thinks I am lol). I only smoke once a week or once a fortnight.
