Mayor Muriel Bowser signed a bill today to increase the penalties for businesses caught selling synthetic drugs.

The bill, “The Sale of Synthetic Drugs Emergency Amendment Act of 2015,” was introduced by Bowser last month in response to the increasing number of overdoses on synthetic marijuana and synthetic drug-related crime in the D.C. area as of late.

Most recently, a woman high on K2—a form of synthetic pot—was arrested after she abandoned her 10-month-old baby on a crowded downtown D.C. street. And Jasper Spires, the 18-year-old accused of slaying 24-year-old Kevin Sutherland on a crowded Metro train, was suspected of being high on synthetic marijuana, charging documents say.

Under the bill, MPD Chief Cathy Lanier would have the authority to close down any business caught selling synthetic drugs for up to 96 hours. Additionally, businesses caught selling synthetic drugs will be fined $10,000 for the first violation and $20,000 for a second violation, as well as the risk of being shut down for up to 30 days, with the DCRA moving to permanently revoke its business license.

“I have issued a fair warning to business owners who continue to sell and distribute these dangerous drugs” Bowser said in a statement. “Beginning today, any business that possesses synthetic drugs will face harsh penalties for the first offense and will lose their license after a second offense.”
