In the Netherlands the Office of Medical Cannabis (OMC) is the official government bureau that oversees the production and distribution of medical cannabis. It has a monopoly on all cannabis trade, import and export, and can decide on special exemptions to the opium act.
Within the Netherlands OMC distributes exclusively to pharmacies, pharmacy holding GPs, hospitals and veterinarians. Outside of the Netherlands they can also deliver depending on strict agreements between the associated authorities of both nations.
The OMC, in collaboration with the Dutch Health Inspectors, also supervise to ensure the medicine is not used illegally. Unlike the situation in America, cannabis in the Netherlands is prescribed by your local doctor, and picked up from your local dispensary.
