White House Drug Czar Gil Kerlikowske warned people Tuesday against taking the newest synthetic drugs, often marketed as "bath salts" and being sold legally on the Internet and in drug paraphernalia stores.

The powdered drugs are sold under such brand names as "Ivory Wave" or "Purple Wave." Kerlikowske said synthetic stimulants in them have made hundreds of users across the country sick already this year. A Mississippi sheriff's office has said the drugs are suspected in an apparent overdose death there.
