Recreational marijuana is legal in Colorado. The state is also home to a medical marijuana program For recreational use, Coloradans and tourists over the age of 21 are allowed possess or purchase 1 oz at a time. Individuals may also grow 6 plants, with as many as 3 of those plants flowering at one time. For medicinal use, Coloradans can purchase 2 oz of marijuana at once. House Bill 1317, which passed in June 2021, limits concentrate sales to 8 g for medical patients ages 21 and over and limits sales to 2 g for patients between the ages of 18 and 20. The law also requires new medical patients between the ages of 18 and 20 to obtain an additional doctor's approval before receiving a recommendation.

Possession of between 1-2 oz. of marijuana for non-medicinal users is a petty offense punishable by a fine no more than $100. Possession of 2-12 oz is a misdemeanor. Possession of between 2-6 oz may result in a punishment of up to 12 months of incarceration and a fine of $700, while between 6-12 oz may result in a punishment of up to 18 months of incarceration and a fine of $5,000. Possession of more than 12 oz of marijuana is a felony punishable by a maximum term of imprisonment of 2 years and a fine of $100,000. Cultivation of 6-30 plants is a felony that may result in a penalty of 6-24 months of incarceration and a maximum fine of $100,000, while cultivation of more than 30 plants may result in a sentence of 2-6 years of imprisonment and a fine of $500,000. Use is public places is still illegal, as is drugged driving.
