“Amendment 64: The Regulate Marijuana Like Alcohol Act of 2012,” amends the Colorado state constitution to allow persons over 21 to possess up to one ounce of marijuana and grow up to six marijuana plants for personal use. It also authorizes the licensing of retail facilities for sales of marijuana to adults. Public consumption and unlicensed sales in the state will remain illegal. The licensing provisions of the amendment will not go into effect until 2014. This is intended to provide the state time to develop regulations for the sale and taxation of marijuana. The personal use and cultivation provisions, however, become effective as soon as Governor John Hickenlooper signs the bill, which by state law must be within 30 days of the November 6 vote. Employers may continue to enforce their drug-testing policies against employees and applicants who test positive for marijuana, to publish and enforce policies prohibiting the possession or consumption of marijuana during working hours, and to discipline any employee whose job performance is impaired because of the use of marijuana.
