Well, I've only had it a few times, when I was in college. We lived in D.C. and used to buy weed laced with the stuff from the guys that hung out on the corner. We called it "Gumby" because it made us feel all rubbery.....never had a bad experience though. Our cat did eat some of the "Gumby" though (no, we didn't give it to her!). She disappeared and we never saw her again.
