Tried it once a long time ago. Pretty intense for about 30 seconds, then nothing. No side effects, no comedown. There was an extremely uncomfortable body high that came along with it. (Like that feeling when your foot goes to sleep, but it's your whole body.) The hallucinations were extremely vivid & visual. Not something I would care to experience again. Plus, the smoke tastes absolutely awful. Nothing like good ol' mary-joo-wanna.
