What Is 7-Hydroxymitragynine? Risks and Dangers of 7-OH
7-hydroxymitragynine, usually shortened to 7-OH, is the most potent opioid-active compound associated with the kratom plant. It occurs in leaf kratom only in trace amounts, but the tablets, gummies, and shots sold as "7-OH" concentrate it.
Because it acts on the same receptors as prescription opioids, these products carry a much higher risk of dependence, withdrawal, and overdose than kratom leaf, and their strength is not consistent from one product to the next.
What Is 7-Hydroxymitragynine?
7-OH is an alkaloid found naturally in the leaves of Mitragyna speciosa, the tropical tree kratom comes from. Kratom leaf contains more than 40 alkaloids, and 7-OH is present in only trace amounts, generally well under 2 percent of total alkaloid content.
The products causing concern are not plain kratom powder. They are concentrated, isolated, or semi-synthetic preparations designed to deliver far more 7-OH than any leaf product would, pressed into tablets or mixed into gummies, shots, and powders.
7-OH binds to mu-opioid receptors, the same receptors involved in the effects of morphine and hydrocodone. That is why these products behave more like opioids than like an herbal supplement, and why dependence can develop the way it does with opioids.
What 7-OH Does to the Body
Effects depend on dose, how often someone uses, and which product they took. Lower amounts often feel stimulating. Higher amounts produce opioid-like effects.
What People Seek
- Pain relief
- Euphoria and mood lift
- Relaxation and reduced anxiety
- Energy at lower doses
What Often Comes With It
- Sedation and heavy drowsiness
- Mental clouding and slowed reactions
- Nausea and constipation
- Reduced motivation
Timing
- Onset usually 15 to 45 minutes when taken orally
- Peak effects often within 2 to 3 hours
- Effects commonly last 4 to 6 hours
- Tablets may act more slowly than powder
The strength is unpredictable. Labeling on these products is inconsistent, and some combine 7-OH with other active ingredients. Two tablets that look identical can produce very different effects, which is part of what makes overdose possible.
How Addictive Is 7-OH?
Regular use can build tolerance quickly. As tolerance grows, people need more to get the same effect, and the reason for using shifts from feeling good to avoiding feeling sick. That cycle is the same one that makes opioid dependence hard to break, and it can take hold within weeks of daily use.
Many people who contact us started with kratom for pain, energy, or anxiety, moved to 7-OH products because they worked better, and only realized how dependent they had become when they tried to stop.
7-OH Withdrawal
Stopping after regular use produces opioid-type withdrawal. Symptoms usually begin within 6 to 12 hours of the last dose, peak over the first few days, and ease across roughly a week, with sleep problems, low mood, and cravings often lasting longer.
Common symptoms include anxiety and restlessness, sweating and chills, muscle aches, nausea, stomach cramps, diarrhea, insomnia, and strong cravings.
Withdrawal is rarely dangerous by itself, but it becomes a medical concern with severe vomiting or diarrhea, during pregnancy, or when alcohol or benzodiazepines are also involved.

Risks and Dangers
These products are often marketed as natural or herbal. That framing does not match how they behave in the body.
Health risks
- Addiction and physical dependence
- Opioid-type withdrawal
- Respiratory depression at high doses
- Sedation and impaired judgment, including while driving
- Nausea, vomiting, and constipation
- Problems with memory and concentration
Signs of overdose: call 911
- Slow, shallow, or stopped breathing
- Unresponsiveness or loss of consciousness
- Extreme sedation and confusion
- Severe vomiting or poor coordination
Any breathing difficulty is an emergency. If naloxone is available, use it, since 7-OH acts on opioid receptors. For poisoning questions, call Poison Help at 1-800-222-1222.
Mixing multiplies the danger. Combining 7-OH with alcohol, benzodiazepines, other opioids, or sleep medications increases the risk of respiratory depression, and products bought without regulation may contain more than the label says.
Legal Status and Public Health Warnings
There is no FDA-approved medical use for 7-hydroxymitragynine. In July 2025, the FDA recommended that concentrated 7-OH products be controlled under the Controlled Substances Act, describing them as an emerging opioid threat.
Federal action has continued since then. The DEA has moved to place several 7-OH-related synthetic compounds in Schedule I, and a separate action covering 7-OH itself above a set concentration has been working its way through the federal rulemaking process.
State law is a separate track. Several states, including Alabama, Arkansas, Indiana, Rhode Island, Vermont, and Wisconsin, already ban kratom or 7-OH products, and others restrict them through age, labeling, or packaging rules. Because this area is changing quickly, check your state's current law rather than assuming a product sold in a store is legal where you live.
Getting Help for 7-OH Use in Georgia
Because 7-OH acts like an opioid, the treatments that work for opioid use disorder apply. That can include medication-assisted treatment with buprenorphine or naltrexone, therapy for the pain or anxiety the product was covering, and dual diagnosis care when depression or anxiety is part of it.
