I've smoked some shit that tasted like soap before. It turns out that my chick was carrying it in her purse and it picked up some odor from some girly powder or make up that she had in her purse with it.
hahaha...........like I said, my chick had the weed in her purse and she had some of her makeup and gear in there too and the weed or maybe just the rolling paper absorbed some odor from her stuff.
