ecstasy usually included w/acid in it.If you're not planning on getting high off of disco biscuits don't let ppl that are on it touch you because the drug seeps through pores in the skin..if you're looking to get contact high then the fastest way for you to do that is for the one who is rollin'(on E)to keep touching your face constantly...
