What Is 7-Hydroxymitragynine (7-OH)?
7-Hydroxymitragynine — commonly called 7-OH — is a potent, opioid-like alkaloid derived from the kratom plant (Mitragyna speciosa). While it occurs only in trace amounts in natural kratom leaf, concentrated 7-OH products now sold in gas stations and smoke shops can be many times stronger, carrying a real risk of dependence and overdose.

Understanding the compound
7-OH is a metabolite of mitragynine, the primary alkaloid in kratom. In the natural leaf it makes up a tiny fraction of total alkaloids. Manufacturers, however, can isolate and concentrate 7-OH into tablets, shots, and gummies that deliver far higher, opioid-like doses.
Because 7-OH binds strongly to the brain's mu-opioid receptors — the same receptors targeted by morphine and oxycodone — concentrated products can produce euphoria, sedation, tolerance, and physical dependence.
How 7-OH affects the brain
As a mu-opioid receptor agonist, 7-OH mimics the effects of traditional opioids. Repeated use rewires the brain's reward system, leading to tolerance (needing more for the same effect) and dependence (needing the drug to feel normal).
Concentrated 7-OH products
Marketed as 'natural' or 'plant-based,' concentrated 7-OH products are frequently sold without meaningful regulation or dosing standards. Labels are often inconsistent, and potency can vary dramatically between batches.
- Tablets and capsules marketed as 'extra strength'
- Liquid shots and tinctures
- Gummies and edibles
- Vapes and concentrates
Why 7-OH is dangerous
Often called a 'gas station opioid,' 7-OH carries the addiction and overdose risks of pharmaceutical opioids but with far less oversight. Users may not realize how potent these products are until dependence has developed.
