Adult-Use Rules in Colorado
Colorado voters approved adult use through Amendment 64 in 2012, and licensed stores opened in 2014. The legislature's marijuana handbook is our main source for the limits below. The state's own cannabis site is inconsistent on possession, so confirm before you rely on a number.
- Possession: up to 2 ounces. The state's Laws about cannabis use page says adults can buy and possess up to 1 ounce in one section and up to 2 ounces in another. The legislature's handbook and the text of House Bill 21-1090 treat 2 ounces or less as legal.
- Home grow: adults 21 and older may grow up to 6 plants, with no more than 12 plants cultivated on a residential property. No permit or medical card is required for recreational home grow. Medical patients may possess 2 ounces of usable medical marijuana and up to 6 plants, only 3 of them flowering, per the legislature's summary.
- 2026 changes: revised Marijuana Enforcement Division rules took effect Jan. 5, 2026. They mainly cover business fees, product safety, contaminant testing and certain manufacturer requirements, not consumer limits.
The Colorado Medical Marijuana Registry
The Department of Public Health and Environment runs the registry. The most recent official application fee we found is $52, non-refundable, effective Oct. 15, 2024, and it is required each time you submit an application. Older pages list $25 and $29.50, which are out of date.
- Eligibility: adult patients must live in Colorado, be 18 or older and have a qualifying condition with written documentation from a licensed physician.
- Validity: the state constitution sets expiration one year from issuance. A physician can set a shorter term for a patient with a disabling condition, no less than 60 days and no more than one year.
- Processing: online applications with all correct information are approved in 1 to 3 business days. Mailed applications take about 6 to 8 weeks.
- Conditions list: our sources did not include the full list, so read it on the registry site.
Opening a Dispensary in Colorado
Open where local authorities allow Regulator: Colorado Marijuana Enforcement Division
A consultant summary says a Level 1 retail store pays $3,120 to the Marijuana Enforcement Division and $2,500 to the local jurisdiction at application, then $5,620 a year later, citing the MED fee schedule effective Jan. 5, 2026. The same source says all MED fees except social equity fees rise 2.4 percent on Nov. 1, 2026. Fort Collins lists a 2026 retail store license fee of $3,379 and an operating fee of $5,632 as an example of city fees, which can differ from the state's. Older MED rule PDFs show far higher numbers, such as $5,000, and are out of date. You usually need local approval first, because the local authority decides whether to accept new business licenses.
