Adult-Use Legal

Quick Facts

1 oz (28g) flower

2 oz flower

Transport Rules

Cannabis must be in a sealed container, not accessible to the driver or any passenger. Store in the trunk when driving. Never transport across state lines into Utah, Kansas, or Nebraska — all remain illegal states with active enforcement.

Medical Reciprocity

No Reciprocity

Colorado does not recognize out-of-state medical cannabis cards. All tourists purchase from adult-use retail.

Dispensaries & Purchasing

Robust adult-use market statewide. Denver has the highest concentration of dispensaries. Mountain resort towns (Aspen, Breckenridge, Telluride) have local dispensaries.

Purchase limit: 1 oz flower per transaction

Where You Can Consume

Illegal in public spaces. Denver and some other cities have licensed social consumption venues (Amsterdam-style cafes) where on-site consumption is permitted. Hotel rooms are generally prohibited unless property designates a smoking area.

Frequently Asked Questions

Can tourists buy marijuana in Colorado?

Yes. Any adult 21+ with valid ID can purchase from a licensed Colorado dispensary. You do not need to be a Colorado resident.

Can I use cannabis at a ski resort in Colorado?

Most ski resorts sit on federally leased land, meaning federal law applies and cannabis is prohibited. Resorts enforce this policy. Consume legally at your lodging before heading to the mountain.

Can I take Colorado weed back to my home state?

No. Crossing state lines with cannabis is a federal crime regardless of your home state's laws. This includes driving, flying, or mailing cannabis out of Colorado.
