"The Drug Enforcement Administration on Tuesday banned for at least a year the chemicals used to make 'K2' and 'Spice,' popular smokable herbs that mimic the marijuana high.
The DEA used its emergency power to control five chemicals used to coat the herbs. It classified them in Schedule I, the most restrictive category under the federal Controlled Substances Act. Schedule I drugs are found to have a high potential for abuse and no accepted medical use...
The emergency ban is effective for a year and can be extended for six months.
Federal scientists will study the chemicals, abuse data and the potential for addiction to determine whether the chemicals should be permanently controlled."
