These are definitely pipes but they may still be worth taking if you have 'em...I tested 'em for a friend and they just fizzed and didn't change colors...He went ahead and ate one anyways, he said it was one of the best pills he'd ever taken (and I've given him some great pills before)...he said you can definitely tell it's not a legit roll but that it felt more like X than any pipe pill he had taken before, plus he was hallucinating pretty hard off 1. He only took 1 all night and was fucked up for like 8-9 hours then went to sleep...he said it felt kinda like candyflipping and he felt great the entire time, no sickness, said he'd blow a whole paycheck on these if he could find 'em again.
Now by all means, be careful. If you're going to take 'em, take only 1 cause that should clearly be more than enough for most people. Also be wary that these are trippy pipes and those tend to cause a lot more of the nasty side effects in people...My friend had a great time on these, doesn't mean you're going to as well, then again you could have as much fun as he did so that's your call. Just remember to go into the experience knowing it's not real MDMA and that should help to make it as fun as it could be.
