This week, MedMen and PharmaCann announced the termination of MedMen’s acquisition of PharmaCann, which would have doubled MedMen’s market reach and given the company a presence in 12 U.S. states. Elsewhere, the Mayo Clinic released a report that characterizes the lung damage caused by vaping-related pulmonary illnesses as something more akin to chemical burns than anything else—meaning the toxic fumes of vaporized oil may be the more specific culprit of the crisis.

  • MedMen and PharmaCann have terminated a $682-million acquisition deal that would have allowed MedMen to purchase PharmaCann in an all-stock transaction, doubling MedMen’s market reach and giving the company a presence in 12 U.S. states. MedMen is still getting one of PharmaCann’s two growing facilities, a dispensary and a license to open another retail location in Illinois in exchange for forgiving a line of credit that MedMen had extended to PharmaCann, which totaled about $21 million.
