Im not sure, but i dont tink im alone in the world of twitching or shakes!!! Ive become notorious amongst my smoking mates as "the twitch" when were smoking. Meself n 3 great fellas in college smoke alot, we smoke a nice bit of weed and herbal smoke but predominatly hash. But no matter what we smoke dere ll come a stage, usually after bout an hour n half of good smoking, i ll start!! it always starts in my legs, either a short sharp twitch or foot tappin, witout fail this ll happen me. I dont mind it n it doesnt really bother me as it provides some comic relief from usually stressfull games of "CUP". Just wondering does anyone else feel my plight!!!!
