You must be 21 and older to buy, possess or use retail marijuana. It is illegal to give or sell retail marijuana to minors.

Licensed retail locations are the only legal place to purchase marijuana, which means that it’s also illegal for you to re-sell marijuana you’ve purchased.

Retail marijuana is intended for private, personal use. Such use is only legal in certain locations not open or accessible to the public. Marijuana may not be consumed openly or publicly.

Since Amendment 64 went into effect in late 2012, adults 21 and older have been allowed to possess up to 1 ounce of retail marijuana.

It’s illegal to leave Colorado with any marijuana products. Additionally, Denver International Airport has banned the possession of marijuana products on its property. Mailing marijuana from Colorado is also illegal.

It is illegal to drive under the influence of marijuana and it can result in a DUI, just like alcohol. Anyone with 5 nanograms or more of delta 9-tetrahydrocannabinol (known as THC) per milliliter in whole blood (CRS 42-4-1301) while driving can be arrested for DUI. The consequences of DUI is dependent on the driver but they can include fines, jail time and a revoked license.

It is up to the discretion of the hotel if it allows marijuana smoke to be consumed in their smoking rooms (the Colorado Clean Indoor Air Act limits all smoking to at most 25 percent of rooms). You should ask the hotel if they allow it. Denver city laws prohibit marijuana consumption on hotel balconies if visible from any public place.
