Marijuana is addictive like any drug, I'm not sure, but the strain might factor into it. Also it's not like you're going to be puffing on a pipe, join,t or bong, or munching on brownies every waking moment so you'll probably not get addicted, I think it's really only in cases of heavy use. I actually have no idea, looking at
this it claims that marijuana is only addictive as a form of escape from reality, then again, people have been driven to schizophrenia from it.
I know it's personal but if you don't mind how old are you? :P
One last thing, I hear that places like Amsterdam are planning to deny non-citizens access to marijuana, I've no idea where they are with that.
Also if you're not just yanking our chain could you post your experience here?
If you remember a damn thing.
