There are also those for whom pot/grass/weed/maryjane/etc. is addictive and becomes a substance which they cannot manage to get through a day without. In many cases it also serves as what is known as a gateway drug towards other harder drugs such as cocaine, heroin, acid, etc. and with many, alcohol as well. Each person is different.

Some are addicted to food-some just to cheeseburgers-I become quite depressed when I eat too many cheeseburgers and find my weight increasing or when I spend too much on cellphones and that just makes me go completely crazy. So, it seems I can get depression and mental illness without pot (I am probably not alone on that).

My partner, is one who is addicted to just about anything-he has had drugs, alcohol, food, sex, internet, movies, cars, the list goes on... There are many similar to him. He attends those AA meetings and occasionally some OA meetings (which for years I thought was about me with those letters). Recently, he asked me along on an open AA meeting and people kept going on about having the disease of More. As in always wanting More. I suppose that's his situation-occasionally I border over into it.
