The problem with pot (I used to be a very heavy user) is that to those that use it, it really doesn't seem like a big deal. I used to smoke 8 times a day easy, and I live in a town in Quebec where EVERYBODY smokes it ALL THE TIME. It goes with that whole hippy, freethinker attitude that "it's natural, dude, God gave us pot because he wants us to be happy."
Unfortunately, this may not exactly be the case. While it may seem normal for people who do it all the time and have not yet experienced any negative side effects, or are simply blind to the negative effects because of their use of the drug and their outlook on life created by their use of the drug, it is not to be taken lightly. People claim that it is only a mental addiction... not true. I needed it because without it I wasn't hungry, I wasn't happy & couldn't sleep. I literally wouldn't look at my supper, and tossed and turned for 5 hours when I had to go without it for a couple of days, 3 years ago.
I suppose it effects different people in different ways. I used to do it all the time, and suffered only from paranoia and a lack of motivation when I was doing it all the time. I quit because I wanted to get healthy, and because I thought that it would make me go Schizophrenic (which it can do), but Schizophrenia runs in my family. Last time I smoked pot, on Christmas, after a couple months of complete sobriety, I thought I would lose my mind. My heart rate went crazy, I got really paranoid, and I felt all sorts of weird things going on inside my body. Almost ruined my Christmas.
I can't hang around with my friends anymore, because when I go over there they all seem so small-minded, staring at the television, smoking a bowl, it makes me angry... but I'm just a jerk.
I just realized that this has nothing to do with your problem, I'm sorry, it's a stupid personal story. Maybe it gives some insight all the same.
Tell him to give it a break. When I used it all the time, I couldn't imagine going without it. Maybe he feels the same way. But if he stops for a couple weeks, it will leave his system, he will not longer depend upon it to eat & sleep, and he'll gave more energy and a clearer head. The trick is to get him to stop in the first place.
Good luck!
Well first off, he has to be the one who wants to quit. Another person telling you to quit is one reason, but you have to want to do it for yourself. If he is willing to quit, i would recommend NA meetings, they help a ton. How long has he been smoking and how much? Also if he does decide to stop there is a chance that he will be very moody for a while and have some anxiety. I experienced this when i stopped smoking. I would smoke about 1.8 grams a day, but everyone is different. I hope he wants to stop and my heart goes out to you, remember that it is an addiction, and its hard to overcome, but it can be done. Just be there for him and i hope the best for you two in the future. Good luck
