I've done X about 10 times and it has only hit me about 6 of those times........after rolling one time i had crazy dreams and i started forgetting a lot of things.....I will lose my train of thought in the middle of a sentence....and i cant concentrate on something for a long period of time....dont get me wrong, the drug is wonderful and has to be the best feeling i have ever felt....but im more worried about long-term effects than rolling anymore!! i warn u, it may be fun... but LIMIT yourself...only one time could kill u or maybe not do anythingto u...its ur gamble i cant believe people are taking 15 at a time (deathwish).....but the real test will be 40 yrs from now when my brain will start deteriorating faster than otherrs.......think before you pop!!!!!!1
