SIOXU FALLS, S.D. (AP) - A South Dakota man has pleaded guilty to selling synthetic drugs.

Federal authorities say 24-year-old Brandon Morrison sold the hallucinogens to businesses in Sioux Falls. The drugs were then sold to customers.

Morrison pleaded guilty Friday to one count of conspiracy to distribute a controlled substance and one count of money laundering. He allegedly deposited the illegal proceeds into his personal bank account.

Authorities say Morrison knew customers were ingesting the substances to get high.

Morrison faces a maximum penalty of 30 years in prison on the two charges. Sentencing is scheduled for Aug. 2.

A large synthetic drug case in North Dakota has resulted in more than a dozen arrests, including a Texas man accused of supplying the substances that led to two the overdose deaths of two teenagers.
