Kratom Legal Status in Colorado

Kratom is legal to buy, sell, and possess in Colorado for adults 21 and older as of October 2026. The state regulates kratom through SB22-120 (2022), which sets a 21+ age requirement and labeling rules, with its prohibitions taking effect July 1, 2024. Kratom and its primary alkaloids, mitragynine and 7-hydroxymitragynine, are not scheduled under Colorado law.

Colorado regulates kratom through SB22-120 rather than through a bill titled the Kratom Consumer Protection Act (KCPA), but the state’s rules cover similar ground. In 2025, lawmakers added SB25-072, signed May 29, 2025, which caps 7-hydroxymitragynine (7-OH) at 2% of total alkaloids, bans synthetic alkaloids, and treats violations as deceptive trade practices. For a broader look at how states handle kratom regulation, visit the kratom legality hub.

At the federal level, the kratom plant and mitragynine are not controlled substances. The FDA has issued import alerts and advisory statements regarding kratom but has not scheduled it. The DEA temporarily placed mitragynine pseudoindoxyl, MGM-15 and MGM-16 in Schedule I effective August 26, 2026, and on October 14, 2026 it published a revised notice of intent to temporarily schedule 7-OH and mitragynine pseudoindoxyl above a concentration threshold, an order that can take effect on or after November 13, 2026. Locally, the Town of Castle Rock banned retail kratom sales in September 2026 (use and possession remain legal there).

Age and Purchase Requirements

Under SB22-120, kratom may not be sold to anyone under 21 in Colorado. Federal law does not set an age requirement for kratom products, so the state rule applies to both local shops and online vendors shipping to Colorado addresses. Some retailers nationwide use an 18+ or 21+ house policy, but in Colorado the 21+ state rule controls.

Colorado law also sets labeling requirements for kratom products, and SB25-072 limits 7-OH to 2% of total alkaloids and prohibits synthetic alkaloids. Consumers in Colorado should still look for vendors that publish Certificates of Analysis and clearly label their kratom products.

Colorado has a thriving kratom retail scene, particularly in Denver, Boulder, and Colorado Springs. Smoke shops, wellness stores, and specialty kratom shops all carry products (retail sales are not allowed in Castle Rock). However, quality and pricing vary widely at local retailers.

⚠️ Quality Matters: Colorado law requires labeling, a 21+ age check, and a 2% 7-OH cap, but product quality still varies between shops. Always ask for lab results and check for proper labeling. Learn what to look for in quality kratom.

Is 7-OH (7-hydroxymitragynine) legal in Colorado?

KCPA LIMIT

SB 25-072 caps 7-OH at 2% of total alkaloids and bans synthetic alkaloids; 21+ under SB 22-120.

A Kratom Consumer Protection Act caps 7-OH as a share of total alkaloids and bars adulteration with synthetic alkaloids.

Federal status: 7-OH is not yet federally scheduled, but the DEA filed notices of intent on July 1, 2026 and a temporary Schedule I order is expected on or after August 5, 2026, effective the day it publishes. That will apply in Colorado regardless of state law.
