The Adult Use of Marijuana Act (AUMA) became effective on November 9, 2016.  The AUMA legalizes personal consumption, personal cultivation and a commercial cannabis industry.  The following summarizes some of the key provisions in the AUMA.

Personal Consumption and Cultivation:

  • Legalizes cannabis use for persons over 21 years of age.
  • Allows for persons over 21 to possess, transport, purchase, obtain or give away up to 28.5 grams of non-concentrated or 8 grams of concentrated marijuana.
  • Persons over 21 years of age are allowed to cultivate up to six (6) marijuana plants within a private residence, inclusive of within a greenhouse or other structure on the same parcel of the property that is not visible from a public space.  A residence includes single-family homes, multi-family apartment units and mobile homes.
  • No smoking of marijuana is allowed in public places. 
  • No smoking of marijuana is allowed where smoking tobacco is prohibited.
  • Local governments may reasonably regulate but not prohibit personal indoor cultivation.
  • Local governments may regulate or prohibit personal outdoor cultivation.

Commercial Cannabis Business Licensing Categories

The AUMA provides for up to 19 different types of state licenses for commercial cannabis.  These business license types largely mirror those provided for in the Medical Cannabis Safety and Regulation Act (MCRSA).  The MCRSA is specific to medical cannabis and will coexist with the AUMA.
