I had someone tell me they spread toothpaste (Colgate Wintergreen w/ Baking Soda) around a cigarette, let it dry, smoked it, and "got fucked up". Is there anything in toothpaste that would remotely fuck you up?
Yes, but it HAS to be the Oral*B bubblegum-flavored Sesame Street stuff...your friend got fucked up on Colgate? Haha, poser. You can increase it's potency by mixing it with an equal amount of vinegar and letting that sit in the fridge for a week...but I wouldn't waste my time smoking it, much better to freebase it.
HaHa I dare someone to try it and come on here and tell us exactly how fucked up they are. I personally think smoking anything will fuck you up. Our brains just dont know whats going on, unless its a habit.
