ST. PAUL — Minnesota has joined the ranks of states where marijuana is a legal medicine.

Gov. Mark Dayton on Thursday signed legislation that sets up a restrictive medical marijuana program. It has tight controls over qualifying conditions and the form its available in. People won’t be able to smoke it legally or access it in leaf form.

The compromise bill upset some medical marijuana advocates, who say many people who need relief won’t get it. But legislative backers say it is a positive first step that satisfied concerns of law enforcement and doctor groups.
