Thanks to new federal legislation, Delta-8-THC is popping up all over the U.S., but it's legal status is still inconsistent from state to state. Is Delta-8-THC legal in Colorado? Or is the cannabis-pioneer picky about THC within state lines?

Unfortunately, Colorado isn't as open to Delta-8 as it is Delta-9, the primary cannabinoid circulating the state's legal cannabis market.

Here are the technical details behind Colorado Delta-8 laws:

Key Takeaways

  • Delta-8 is a cannabinoid derived from legal hemp, and is therefore legal according to federal legislation.
  • Colorado declares that Delta-8-THC, a THC isomer, is a controlled substance according to state law.
  • Colorado laws prohibit the sale of Delta-8 within the state, so Delta-8-THC is not easily accessible in Colorado.
  • In legal areas, many people buy Delta-8-THC products made from hemp online.

Colorado Delta 8 THC Laws

Many states, like Alabama and California, clarify that tetrahydrocannabinols derived from legal hemp fall under the protections of hemp's legal status. Colorado has legalized hemp and CBD, but it’s stance on Delta-8 is very different.

Unfortunately, in Colorado, Senate Bill 14-184 clarifies that all tetrahydrocannabinols, including Delta-9, are defined the same way by state law. That means that any hemp material with a Delta-8-THC content that exceeds the legally allowable amount of THC (0.3%) is technically classified as "marijuana" by state law.

Of course, cannabis is legal for recreational and medicinal purposes in Colorado. By this logic, Delta-8-THC should be available in state licensed dispensaries. So, is it?

It's a little unclear—the state's Controlled Substances Act technically lists THC isomers as prohibited substances. You may find Delta-8 products in Colorado dispensaries, but they walk a fine line between legal and illegal.

In general, no, Delta-8-THC is not openly legal in Colorado and may be difficult to find in the state.

Here are some highlights from the official legislative text in Colorado:


35-61-101. Definitions.

(5) “Delta-9 tetrahydrocannabinols” has the same meaning as “tetrahydrocannabinols” as set forth in section 27-80-203 (24), C.R.S.

Colorado Revised Statutes Title 27. Behavioral Health

Section 27-80-203

(24), C.R.S(24) (a) “Tetrahydrocannabinols” means synthetic equivalents of the substances contained in the plant, or in the resinous extractives of, cannabis, sp., or synthetic substances, derivatives, and their isomers with similar chemical structure and pharmacological activity, such as the following:

(I) ¹cis or trans tetrahydrocannabinol, and their optical isomers;

(II) 6 cis or trans tetrahydrocannabinol, and their optical isomers;

(III) 3,4 cis or trans tetrahydrocannabinol, and their optical isomers.

(b) Since the nomenclature of the substances listed in paragraph (a) of this subsection

(7) “Industrial hemp” means a plant of the genus cannabis and any part of the plant, whether growing or not, containing a delta-9 tetrahydrocannabinol concentration of no more than three-tenths of one percent on a dry weight basis.


18-18-102. Definitions.

(18) “Marijuana” means all parts of the plant cannabis sativa L., whether growing or not, the seeds thereof, the resin extracted from any part of the plant, and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds, or its resin. It does not include fiber produced from the stalks, oil, or cake made from the seeds of the plant, or sterilized seed of the plant which is incapable of germination if these items exist apart from any Uniform Controlled Substances Act 6 of 53 2016 other item defined as “marijuana” in this subsection (18). “Marijuana” does not include marijuana concentrate as defined in subsection (19) of this section.

(35) (a) “Tetrahydrocannabinols” means synthetic equivalents of the substances contained in the plant, or in the resinous extractives of, cannabis, sp., or synthetic substances, derivatives, and their isomers with similar chemical structure and pharmacological activity, such as the following:

(I) ¹Cis or trans tetrahydrocannabinol, and their optical isomers;

(II) 6Cis or trans tetrahydrocannabinol, and their optical isomers;

(III) 3,4Cis or trans tetrahydrocannabinol, and their optical isomers.

Legal hemp flower, which is the primary source for Delta-8 products made in areas where it is legal. Is Delta-8 a Controlled Substance in Colorado?

The state of Colorado clarifies that all isomers of THC are considered controlled substances within the state. It makes no special provisions for tetrahydrocannabinols derived from legal hemp. Instead, it bulks all tetrahydrocannabinols under the same legal definition, meaning the penalty for illicit possession of Delta-8 is likely the same as that of Delta-9-THC.

Delta 8 THC Possession Limits in Colorado

Because Delta-8 has not technically been recognized as a legal substance by Colorado State law, there are no set possession limits specifically for Delta-8.

Is Cannabis (Delta 9 THC) Legal in Colorado?

Cannabis, and subsequently Delta-9-THC, has been legal in Colorado since 2012 for recreational use and was approved for medicinal use in 2000. Of course, there are strict regulations on how and where Delta-9 products can be bought and sold. Special possession limits also apply to Delta-9 products bought or sold in Colorado.

Where to Buy Delta 8 in Colorado?

One popular formula, the Delta-8 vaporizer, is available in legal stores and online.

Because state law technically classified Delta-8-THC as a controlled substance, it's difficult to find Delta-8 in the state. Delta-8 used to be accessible in dispensaries across the state but has since disappeared from shelves in response to updates to state law.

In places where Delta-8-THC is legal (like neighboring states New Mexico, Wyoming, and Nebraska), many people prefer to shop online. It's advisable to proceed with caution when choosing a Delta-8 distributor. Shopping online allows you to buy directly from a brand or manufacturer, instead of purchasing through a third-party vendor that may not fully understand Delta-8 effects and uses or the laws surrounding Delta-8 products.

Do You Have to Be 21 to Buy Delta-8 in Colorado?

The sale of Delta-9-THC products is prohibited in Colorado, so there are no age limits set forth by state law.

Is Delta 8 Legal in All 50 States?

Delta-8-THC is currently federally legal under the context of the Hemp Farming Act of 2018, but each state has the right to determine their own stance on tetrahydrocannabinols derived from hemp. Delta-8-THC is illegal in Colorado according to state law, but you should read more about Delta-8 laws by state to determine the legality in other areas.
