The owner of the Duluth head shop Last Place on Earth and three of his employees pleaded not guilty Friday to federal charges of selling synthetic drugs, the Duluth News Tribune reports.
Jim Carlson as well as his girlfriend, his son and a former employee were indicted on 54 federal charges earlier this week. They are charged with conspiracy to violate federal regulatory laws and conspiracy to distribute controlled analogue drugs.
Authorities claim that synthetic drugs were misbranded and marketed as incense, potpourri or bath salts.
In a separate court action, a judge's decision is pending to shut the head shop down until attorneys from both sides can present more evidence.
