Depends on the person. Some people(like myself) can smoke every day and when they run out it's no big deal. I personally like to smoke but I usually keep it to the weekends, depends what mood I'm in. However I have had plenty of pot head friends who are what would seem to be weed addicts. They freak out when they dont have any weed and dont seem to function without it. Strange to me but everyone is differant. I agree with the above post- if you have an addictive personality than you are more prone to it. I have noticed that after prolonged smoking(several months of daily use) I am moody and a bit spaced out when I stop smoking. Seems the best thing is to just do it in moderation like anything else. Except sex that is...that is good all the time!
