7-OH vs Kratom: What's the Difference?

7-OH and kratom aren't the same thing. Kratom is a Southeast Asian tree, Mitragyna speciosa, and the products made from its leaves. One compound in that leaf is 7-OH, and 7-OH products concentrate it far beyond what the leaf contains.

That difference matters. Concentrated 7-OH products aren't "natural kratom." For more on each, see what is 7-OH and what is kratom.

7-OH vs kratom at a glance

Source. According to the FDA's 2025 assessment, mitragynine makes up about 66% of the alkaloids in kratom leaf, and 7-OH under 2%. One analysis it cites found 0.05 to 0.15 mg of 7-OH per gram of dried leaf.

Products. 7-OH comes as tablets, gummies, drink mixes and shots. It's sold online and in smoke shops and gas stations.

Legal status. As of November 2026, kratom, mitragynine and 7-OH are not federally controlled. The FDA recommended scheduling certain 7-OH products on July 29, 2025, and said the action targets concentrated 7-OH, not natural kratom leaf. On October 14, 2026, the DEA published a notice of intent to temporarily place 7-OH in Schedule I. It would apply above a set 7-OH threshold. The order can take effect on or after November 13, 2026. State laws also differ (see the FAQ below).

Why concentrates hit harder

7-OH is much stronger than mitragynine at the body's opioid receptors. In a 2004 lab study on guinea pig tissue (Matsumoto and colleagues), 7-OH was about 13 times as potent as morphine and 46 times as potent as mitragynine. The FDA's 2025 assessment says animal data show 7-OH is more than 3 times as potent as morphine at slowing breathing. These are lab and animal results, not human doses.

Kratom leaf works differently. People report stimulant-like effects at lower amounts and opioid-like or sedating effects at higher amounts, though studies haven't pinned down a dose pattern. Your body also turns some mitragynine into 7-OH, but the leaf itself holds only a little.

A concentrated product skips that. It delivers 7-OH directly, in amounts the leaf doesn't contain. Serious harm has been reported: by February 27, 2026, the FDA's adverse event system had 86 reports involving 7-OH, including 9 deaths.

Some 7-OH products also contain other drugs. DEA testing found samples with fentanyl, benzodiazepines such as bromazolam, and ketamine. See kratom drug interactions for what not to mix.

Dependence and withdrawal differences

Both can cause dependence. Stopping regular kratom use may cause mild to moderate withdrawal, and kratom withdrawal is generally milder and shorter than withdrawal from classic opioids. The kratom withdrawal guide covers symptoms and timeline.

7-OH is closer to a classic opioid. The FDA says it causes physical dependence and withdrawal typical of opioids, and there are reports of long-lasting withdrawal after concentrated products. In one published case, 7-OH withdrawal led to agitation, psychosis and breathing problems, and the person needed a breathing tube. Read more about 7-OH withdrawal.

If you're thinking about stopping either one, work with a licensed doctor on a plan. Don't stop high, regular use of 7-OH on your own without medical advice.

When to get help

Call 911 if someone has trouble breathing, slow or stopped breathing, a seizure, chest pain, or can't be woken up. For a possible poisoning, call Poison Control at 1-800-222-1222 or 911. If you're having thoughts of harming yourself, call or text 988.

Frequently Asked Questions

Is 7-OH legal in my state?

It depends on where you live. As of the DEA's October 2026 notice, ten states prohibit 7-OH: Alabama, Arkansas, Connecticut, Indiana, Kansas, Louisiana, Massachusetts, Tennessee, Vermont and Wisconsin. Other states limit it, and laws change often, so check your state's current law.

Is kratom extract the same as 7-OH?

Not necessarily. Products are labeled in different ways, and some sold as kratom have 7-OH added. The DEA's proposal is based on how much 7-OH a product contains, not what it's called.

Can I switch from 7-OH back to kratom leaf to cut down?

Talk to a licensed doctor before you try. No study has tested switching, and both carry a risk of dependence. A doctor can help you make a safer plan.

Does naloxone work on 7-OH?

It appears to. In animal studies, naloxone reversed 7-OH's effect on breathing, and it reversed a kratom overdose in one reported case. If you have naloxone (Narcan), give it and still call 911.

Does 7-OH show up on a drug test?

Not on a standard panel, as far as published data show. Lab tests for kratom compounds exist, but they have to be ordered or added to a panel. Learn more in does kratom show up on a drug test.

The Bottom Line

7-OH products are far stronger than kratom leaf, with more risk of dependence, harder withdrawal and hidden ingredients. 7-OH's legal status is changing, so check your state's law. If you use either one, a licensed doctor can help you plan next steps.
