OKLAHOMA CITY (AP) - A House committee has approved a bill to outlaw various kinds of new synthetic drugs, including so-called "bath salts" and artificial marijuana.

The House Public Safety Committee on Wednesday approved a bill that was requested by the Oklahoma Bureau of Narcotics and Dangerous Drugs.

OBNDD spokesman Mark Woodward says the bill adds 21 new chemical compounds to the list of more than 200 illegal chemicals in Oklahoma.

Woodward says drug agents are "playing a game of cat chasing mouse" with chemists who create new synthetic drugs that aren't technically illegal, prompting the addition of new compounds on the state registry every year.

Woodward says the synthetic drugs are frequently sold at gas stations or convenience stores under names like "Blue Majestic," ''Spice," and "Kryptonite."
