Key Rules
Possession
Patients may possess up to a 90-day supply: 6,367.5g of flower and 1,350g of THC in other products per rolling 90-day cycle. Daily purchase limit: 2.5oz (70.87g) flower + 15,000mg THC; up to 4 days' supply per transaction (283g flower + 60g THC).
Transportation
Medical cannabis must be kept in its original, sealed packaging and stored out of reach of the driver during transport.
Employment

Travel
Medical cannabis may not be taken across state lines. Doing so violates federal law, even into states with their own programs.
