I HAVE NEVER DONE ACID , I GUESS I NEVER FELT THE NEED OR REALLY WANTED TO MESS WITH SOMETHING LIKE THAT. I KNEW SOMEONE WHO USED TO DO IT ALL THE TIME AND DECIDED TO DO IT EVERY DAY FOR A WHILE. EVERY TIME HE DID IT HE WOULD START HEAD BUTTING WALLS AND SHIT , LONG STORY SHORT DUDE IS ALL KINDS OF CRAZY NOW AND IS FOR REAL MESSED UP FROM THE SHIT AND IS ON DISABILITY. EVERY TIME I THINK ABOUT HIM I THINK OF THAT OLD ASS COMERCIAL THIS IS YOUR BRAIN ON DRUGS AND THEY SHOW THE EGG FRYING IN THE PAN, I SWEAR HE COULD BE THE POSTER CHILD FOR BAD ACID.
