Measure 91: Legal Recreational Marijuana in Oregon

Decriminalized and regulated recreational marijuana will take effect for adults in Oregon July 2015, and OLCC will begin accepting license applications for retail businesses on or before January 4, 2016.

  • Administrative rules for retail sales will be created by OLCC by January 1, 2016.
