Effective December 2, 2004, you are no longer required to have a separate controlled substance license for each location in which you prescribe controlled substances. You only need one controlled substance license to prescribe controlled substances in Michigan regardless of the number of locations where you prescribe.

If you are receiving or storing controlled substances, a separate controlled substance license is required for each physical location. If you dispense controlled substances to patients, a Drug Control License is also required for each physical location.
