I have a friend in St Louis and I visit every once in a while. And not to many people smoke weed around there and it is VERY hard to find....unlike Chicago
...or my hometown where it's "everywhere".
My friends sister smoked this K2 stuff and she was messed up. She said it was more of a milder feeling of Salvia. I think it's stupid...just get the real thing and keep in on your property and don't deal/sell it. You will never get caught that way.
