Colorado: Where Legal Cannabis Began
Colorado's Amendment 64 was approved by voters in November 2012, and the state made history on January 1, 2014, when the first legal recreational cannabis sales in the United States took place. Since then, Colorado has been the gold standard for cannabis regulation.
The Marijuana Enforcement Division (MED), part of the Department of Revenue, regulates the industry. Colorado has one of the most mature and competitive cannabis markets, with hundreds of licensed dispensaries statewide.
Buying Cannabis in Colorado
Licensed dispensaries are found throughout the state, with heavy concentrations in Denver, Boulder, Colorado Springs (medical only), Fort Collins, and popular mountain towns. Many dispensaries cater to both recreational and medical customers.
Recreational customers can purchase up to 1 ounce of flower (or equivalent) per transaction. Prices in Colorado are among the most competitive in the country due to the mature market.
Colorado Tourist Guide
Colorado is one of the top cannabis tourism destinations in the U.S. Visitors from any state or country can purchase recreational cannabis with a valid government-issued ID proving they are 21+.
Keep in mind: cannabis consumption is not allowed in most public places, on federal land (including national parks and ski resorts on federal land), or in most hotels. Some Denver establishments hold social consumption licenses. Always ask about consumption policies before assuming it's allowed.
