PIERRE, S.D. (AP) - The South Dakota Legislature has given final approval to a bill that seeks to ban so-called synthetic marijuana and bath salt drugs.

The House voted 63-1 Wednesday to pass the bill, which has already been approved by the Senate. It will take effect as soon as Governor Dennis Daugaard signs it.

The measure adds some of the synthetic drugs to the list of banned substances in South Dakota. It makes it a felony to possess or sell the synthetic drugs.

Law officers say some of the drugs are sold openly in a few stores. They say many people have developed psychiatric and medical problems after taking some of the drugs.
