Can I buy 7-OH online and have it shipped to Colorado?

Shipping to Colorado is generally permitted for products that comply with state regulations, including age-verification and potency limits. Retailers selling non-compliant products into Colorado may be in violation of state law regardless of where the sale originates.

Is kratom the same as 7-hydroxymitragynine in Colorado?

Not exactly. Kratom (Mitragyna speciosa) is the plant; 7-hydroxymitragynine is one of its active alkaloids, which can also be concentrated or semi-synthesized to much higher potencies than occur naturally. Colorado's laws may treat the natural leaf, its alkaloids, and concentrated/synthetic 7-OH differently — see the Legal at a Glance panel above for the specifics that apply here.

What is the minimum age to buy 7-OH in Colorado?

21. Retailers in Colorado are required to verify age before sale. Sales to anyone under 21 can result in licensing consequences for the seller.

Is there a 7-OH potency limit in Colorado?

Yes. Colorado caps 7-hydroxymitragynine content at 7-OH may not exceed 2% of alkaloid fraction; synthetic/semi-synthetic alkaloids prohibited. Products above that threshold are non-compliant and cannot legally be sold in the state. Independent lab audits have repeatedly found 7-OH products on retail shelves that exceed state caps, so lab-certificate verification matters.

What happens if I already bought 7-OH and Colorado's law changes?

Laws typically distinguish between sale (prohibited for retailers immediately) and personal possession (often given a grace period, though not always). When Colorado has changed status in the past, state agencies have usually issued guidance to consumers and retailers. Check the most recent state guidance linked in the Sources section before assuming an existing purchase remains legal.

Because kratom and 7-OH law changes quickly, we re-verify active-legislation states at least quarterly and update the page when new bills, court rulings, or enforcement actions are reported. This is not legal advice — verify the current statute or consult an attorney in Colorado before relying on it.
