Bad juju man... not sure that it's illegal enough in OK as of yet to go to the Big House, though. K2 has screwed some people up hardcore. I've seen a number of folks in the ERs who were wacked out for long periods of time on it. I haven't seen any fatalities from it yet, though. Some kids in Konawa got messed up, one died, but I'm not sure what they were into. I thought it was supposed to have been this stuff, but they ordered it from China or something and may have gotten something totally different? I dunno, just saw a quick news blurb, so I don't recall that whole situation very well. Sorry.
If I recall correctly those kids overdosed on 2C-E.
