States with MMJ Reciprocity
Thirty-four states and the District of Columbia permit some medical use of marijuana, although some are limited to cannabidiol (CBD), and not all programs are operational yet. Of those jurisdictions, only seven:
Arizona,
Delaware,
Maine,
Michigan,
Montana,
Nevada and
Rhode Island, explicitly permit legal medical marijuana visitors to use their medications in state.
Oregon appears to reach the same result through a ruling of the state Court of Appeals. The situation is
not clear in California, and the likelihood of prosecution in Colorado and Washington, where recreational marijuana has been legalized, seems slim.
Even within these states, considerable variation exists as to what is permitted. If, for example, a patient legally uses marijuana to treat glaucoma at home, but glaucoma is not a condition for which it may be used in the state being visited, then the patient cannot use it, even if the visited state normally has medical marijuana reciprocity.
A patient may be permitted to use medication brought from home, but
not to purchasethe same thing from a dispensary. Nevada, on the other hand, has
recently amended its medical marijuana statute to permit out-of-state patients to purchase marijuana at a dispensary on the basis of a sworn affidavit until 2016, after which date it will require cross-checking through a database that has yet to be developed.
Michigan, in an apparent fit of pique, limits reciprocity to residents of only those states that extend the same privilege to Michiganders. It is chaotic, to say the least.
