Oops, I was wrong, just looked at DEA and they DID emergency schedule it Oct 21, 2011. It’s now a Federal Schedule 1 drug like marijuana, cocaine, and heroin. They issues a one-year ban and put it under study.
Good Info...Although I did find
“Eventually it will be Emergency Scheduled then permanently scheduled, then it will be as hard to get as marijuana or heroin.” kinda humorous. ;-)
