ST. PAUL — A legislative panel on Wednesday recommended that Minnesota lawmakers give the state Board of Pharmacy the power to order businesses to stop selling synthetic drugs.

The panel also proposed a statewide educational campaign on synthetic drugs, expanded drug definitions and training for prosecutors. It also recommended giving the Board of Pharmacy the authority to add products to Minnesota’s list of banned drugs.

Members of the House Select Committee on Controlled Substances and Synthetic Drugs released the report Wednesday to give lawmakers time to consider it during the upcoming legislative session.

The panel began its work last year, soon after authorities shut down the Duluth head shop known as the Last Place on Earth and prosecuted its owner for selling banned synthetic drugs.

Despite recent efforts to toughen state drug laws, the problems associated with products such as bath salts and synthetic marijuana continue to grow, said state Rep. Erik Simonson, DFL-Duluth, who chairs the committee. Simonson said a different approach is needed.

“Essentially what we need to do is put another tool or two into the toolbox to give law enforcement and prosecutors a better opportunity to control this problem in their own communities,” he said.

Another recommendation would expand the definition of “drug” in state law to include any compound or substance that induces an effect “substantially similar” to a known illegal drug.

Minnesota Attorney General Lori Swanson said the makers of synthetic drugs have avoided prosecution by simply adjusting their formulas.

“It really became a game of Whac-A-Mole, where as soon as a compound was listed as a named substance and a banned controlled substance, the suppliers would just slightly tweak it to alter its chemical structure,” Swanson said. “Then it would stay off the list. Then the Legislature and the Board of Pharmacy would name new compounds, and on and on it went, as the industry and the sellers tried to get ahead of the laws.”

Lynn Habhegger of Carlton told lawmakers how her son, Corey, overdosed in 2011 on the bath salts he purchased at the Last Place on Earth. She said her son suffered permanent brain damage.

“Corey didn’t lose his life to synthetic drugs,” Habhegger said. “He lost his mind to them, and ultimately we have lost our son and the man he could have become. Corey will never be able to hold a job, go to college, have a profession, serve his country, get married or have a family.”
