Today the yet to be formed Arizona Medical Marijuana Association (AzMMA) had its attorney send a 17 page letter to the Arizona Department of Health Services with its suggested changes to the December 17, 2010, proposed rules.  For the most part, I think its suggested are good and should be adopted by DHS.  The only change I disagree with is AzMMA’s suggestion to increase the Arizona residency requirement to three years.  Proposition 203 does not contain a requirement that owners of medical marijuana dispensaries be residents of Arizona.  Query:  Could that requirement be an unconstitutional violation of the equal protection clause of the U.S. Constitution?
