can you be addicted to cannabis?

[mmiikkee]

hey.. is it possible to be addicted to smoking bud? SWIM has smoked for almost 10 years and could function normally if for some reason didn't have any.. but in the last 4 years has been smoking about an ounce or 2 of kb a week. If he doesn't smoke he can go the whole time without eating, but the second he takes a bong rip he can eat so much (gained 20 pounds in a week.. couldn't get any for a couple days and just loose it all again). He doesn't eat a thing.. not a thing at all unless he smokes. Is that normal and goes away fast or what? It seems like can't sleep.. can't function can't do anything. But so hungry that you are to hungry to eat and if you try you just about throw up. Get to the point where you can't even move becuase you feel like your going to faint from not eating. Well what should this person do? he is now on probation and has to take drug tests. Is his only option to move to a state that allows medical mj?
