Minnesota Governor Mark Dayton (D) has just made the state the 22nd with a medical marijuana program, although the rules governing it are so strict some medical marijuana groups question whether it should really count.

On Thursday he signed into law SF 2470, which was recently approved overwhelmingly in the Minnesota legislature. Dayton said about the new law, “I pray it will bring to the victims of ravaging illnesses the relief they are hoping for.”

The program allows people with certain medical conditions to take part if they have a recommendation from a medical practitioner and they register with the state.

Only two licensed manufacturers with eight distribution centers throughout the state will be allowed to produce and provide the medicine to patients. Patients will be able to get pills or liquids which contain whole plant extracts but will not be able to receive actual plant material. Vaporizing extracts is allowed but not actual smoking. Home growing is prohibited.

This new law will create the most restrictive medical marijuana system in the country.
