Colorado Marijuana Compliance

Colorado marijuana compliance laws allow for the recreational and medicinal use of marijuana. Medicinal marijuana users must meet certain qualifications, and recreational marijuana users must be adults ages 21 and older. Employers do not have to accommodate medical marijuana use, and they can still enforce a drug-free workplace policy that includes marijuana use. They may also test for marijuana use following a work-related accident.

State and federal marijuana laws differ. Colorado permits medical marijuana and adult recreational use under state law. Federally, recreational marijuana remains a Schedule I controlled substance. An April 2026 federal rule moved certain medical marijuana products, including those covered by qualifying state medical licenses, to Schedule III, but federal requirements still apply. Colorado residents and employers should understand both sets of rules.

Colorado Marijuana Laws

Overall Status: Fully Legal

Medicinal marijuana became legal in Colorado in the year 2000, and marijuana for recreational purposes was legalized in Colorado in 2012.

Medical Marijuana: Legal

Adult applicants must be Colorado residents, have a qualifying medical condition, and meet the Medical Marijuana Registry's certification requirements. Minors can qualify too, as long as they and their primary parent meet the residency and application requirements. Every minor needs certifications from two providers.

Applicants ages 18-20 who did not hold a registry card before age 18 and first applied on or after January 1, 2022, generally need annual certifications from two providers at different medical practices. A homebound applicant exception affects the different-practice requirement.

Qualifying medical conditions include cancer, glaucoma, HIV, cachexia, persistent muscle spasms, seizures, severe pain, or severe nausea.

Decriminalized: Yes

People with certain past marijuana convictions may qualify to have their conviction records sealed under Colorado law. Eligibility depends on the offense and the applicable requirements. Colorado also granted pardons for state convictions involving possession of two ounces or less of marijuana, but a pardon does not itself seal the conviction record.

Recreational Marijuana: Legal

Recreational marijuana laws began allowing recreational use of marijuana in 2012. Adults 21 and older, including visitors, may generally possess up to two ounces of marijuana. The possession allowance increased on May 20, 2021. Retail purchases remain subject to separate limits, including a one-ounce flower limit or its equivalent in other products. Marijuana purchases in Colorado must take place in licensed dispensaries throughout the state. Marijuana that contains THC must remain in Colorado and not be used in public spaces.
