The Last Place on Earth in Duluth and two other synthetic drug retailers say they'll appeal the judge's decision. State lawmakers earlier this year passed a ban on synthetic drugs and their "analogs." The retailers argue the law is vague and incomprehensible to anyone besides experts. The judge who tossed out the suit says the retailers don't have enough evidence to back their claims.

Jury selection began Monday in the trial of surgeon Jon Norberg, who is accused of drugging his wife with the powerful anesthetic propofol, the drug that featured prominently in the death of pop singer Michael Jackson. Norberg is accused sexually assaulting his wife Alonna Norberg, alos a doctor, while she was sedated.

An attorney for St. Louis County tells the Duluth News Tribune he expects to file charges against the Last Place on Earth. Police raided the shop in September and reportedly took synthetic marijuana, cash and 31 guns. The shop claims that was illegal search and seizure.

Reports that "designer drugs" can have harmful side effects don't seem to be deterring many customers.

The store's owner says he expects the chemicals will bring in about $6 million in business this year.

Students at the University of Minnesota tell the Star Tribune that the use of legal and illegal prescription drugs has become common on campus, and a new study says one in four adults fake symptoms to get drugs, news that has some doctors calling for tougher screening tests.
