Ilo Leppik, MD, Neurology Professor from the University of MN spoke on Minnesota Medical Cannabis. This is not marijuana to be smoked, and it is certainly not for recreational use. In fact, medical cannabis in Minnesota is quite restrictive. There are only a handful of dispensaries around the state, and users need a prescription to gain access. Medical cannabis is made in factories so that the plant can be purified and certified as pharmaceutical grade. It is taken in pill form, liquid, or oil.
