ST. PAUL, Minn. (AP) - The state has suspended a new clinic promising to help patients get signed up for Minnesota's medical marijuana program, according to an email obtained by The Associated Press.

Minnesota Certification Clinic informed would-be patients in an email Tuesday that it was cancelling all appointments after the state suspended its ability to certify patients. The Bloomington clinic is part of a network of doctors spearheaded by a New York-based firm called MarijuanaDoctors.com to help patients find doctors who will approve their registration.

People seeking medical marijuana need approval from a state-approved doctor before they can register. State law calls for that approval to come from doctors with a history of caring for the patient.

Minnesota Certification Clinic did not return multiple phone calls or an email seeking comment.
