i have done meth and coke a few times cause i smoked some shit that was laced with it but i would never want to touch that shit again. it is great while you are up but when you come down it is a bitch. i wouldnt want to touch meth again too especially since it isnt even natural. it is sick to think some jack ass is making your drug up in some basement or something like that and you arent even quite sure what the hell they exactly put in there. i am just going to stick to the good ole natural bud.
