I smoke a lot of weed probably an equivalent to a quarter to the head but sometimes connects can be dry and i can't smoke =/. Idk if its just me or if anyone else has had this happen; but when I can't get my daily dose of my sweet Mary-Jane I get real anxious, not a nervous anxious though. I also don't have any prior experiences with anxiety before the herb. I guess its not much of a withdrawl but I do start to feel real out of place with myself until I smoke.
