What Is 7-OH?
What Is 7-Hydroxymitragynine?
7-hydroxymitragynine, commonly called 7-OH, is one of the naturally occurring alkaloids associated with Mitragyna speciosa, the kratom plant. It is normally present in kratom leaf in small amounts. The body can also produce 7-OH as it processes mitragynine, the primary alkaloid found in kratom.
7-OH interacts with mu-opioid receptors, which are involved in pain relief, reward, tolerance, physical dependence, and withdrawal. This activity helps explain why concentrated 7-OH products may produce stronger opioid-like effects than traditional kratom leaf. Effects can vary according to the product, amount consumed, other substances used, and the individual.
Why concentrated products differ: Tablets, shots, extracts, and enhanced products may deliver substantially more 7-OH than would normally be found in traditional kratom leaf. Product strength and composition may also vary, increasing the potential for unexpected effects, tolerance, dependence, and withdrawal.
How Are 7-OH and Kratom Related?
Tablets, shots, extracts, and enhanced products marketed specifically as 7-OH may contain substantially higher concentrations than traditional kratom leaf. These products can produce stronger opioid-like effects and may increase the risk of tolerance, physical dependence, and withdrawal. Product strength and composition can also vary.
- Traditional kratom leaf: Contains a mixture of naturally occurring alkaloids and comparatively small amounts of 7-OH. Traditional kratom can still cause tolerance, dependence, and withdrawal with regular use.
- Concentrated 7-OH products: May deliver much greater amounts of 7-OH in tablets, shots, extracts, or enhanced formulations, potentially producing stronger effects and a greater risk of dependence.
How Does 7-OH Affect the Body?
7-OH interacts primarily with mu-opioid receptors in the brain and body. These receptors influence pain perception, reward, mood, and physical dependence. This activity may produce opioid-like effects such as pain relief, relaxation, sedation, and changes in mood.
The same activity can also cause unwanted effects, including nausea, dizziness, constipation, reduced alertness, and impaired coordination. With repeated use, the body may adapt to 7-OH, leading to tolerance, physical dependence, and withdrawal when use is reduced or stopped. Effects vary depending on product concentration, amount consumed, frequency of use, other substances, and individual health.
Commonly Reported Effects
- Pain relief
- Relaxation or sedation
- Nausea, dizziness, or constipation
- Reduced alertness or impaired coordination
Can 7-OH Cause Dependence?
Regular use of concentrated 7-OH products can lead to tolerance, physical dependence, and, for some people, addiction. Tolerance means needing more of the substance to experience the same effects. Physical dependence means the body has adapted to regular use and may experience withdrawal when use is reduced or stopped. Addiction involves continued or compulsive use despite harmful consequences.
These changes can develop gradually. A person may begin taking 7-OH for pain, mood, energy, or relief from another substance, but eventually find that they are using it primarily to feel normal or prevent withdrawal. Dependence is a health concern—not a moral failure—and professional support is available.
Warning signs
- Using more frequently or for longer than intended
- Needing increasing amounts to experience the same effects
- Using 7-OH to feel normal or prevent withdrawal
- Waking during the night or morning needing another dose
- Experiencing persistent cravings
- Making unsuccessful attempts to reduce or stop
What Happens When Someone Stops Using 7-OH?
- Severe Anxiety & Agitation
- Physical Restlessness & Restless Legs
- Insomnia & Disrupted Sleep Cycles
- Profuse Sweating & Hot Flashes
- Chills & Sudden Goosebumps
- Persistent Body & Joint Aches
- Nausea, Cramping & Digestive Distress
Risks of Concentrated 7-OH
- Rapidly increasing tolerance
- Physical dependence and withdrawal
- Profound sedation or lethargy
- Slowed or abnormal breathing
- Nausea, vomiting, or constipation
- Impaired judgment and coordination
- Seizures or other serious reactions
- Dangerous interactions with other substances
- Uncertain product strength or composition
EMERGENCY NOTICE
Call 911 if someone is difficult to wake, has slowed breathing, or collapses. If you have naloxone (Narcan), give it — it reverses opioid overdoses, and 7-OH acts on the same receptors.

Frequently Asked Questions
Straight answers to the most common questions about 7-hydroxymitragynine (7-OH): what it is, how it affects the body, its risks, and where to find help.
What does 7-OH stand for?
7-OH stands for 7-hydroxymitragynine, an alkaloid found in small amounts in the kratom plant (Mitragyna speciosa). The body also produces it when it breaks down mitragynine, kratom’s main alkaloid. Even though it’s a minor part of the leaf, 7-OH is much more potent at opioid receptors, so it contributes to kratom’s opioid-like effects.
Is 7-OH the same as kratom?
No. Kratom leaf contains dozens of alkaloids, mostly mitragynine, with only trace amounts of 7-OH. Products sold as “7-OH” are concentrated, often by chemically processing kratom alkaloids, and deliver far more 7-OH than the leaf ever would. That’s why they behave more like opioids than traditional kratom does.
Is 7-OH legal?
As of September 2026, 7-OH had not yet been federally scheduled, but that is changing. The FDA recommended placing 7-OH under federal control in July 2025, and in July 2026 the DEA proposed temporarily placing concentrated 7-OH in Schedule I. In August 2026 the DEA temporarily scheduled three closely related synthetic compounds, and several states have already banned 7-OH products. Laws are changing quickly, so check the current rules where you live.
Is 7-OH an opioid?
Chemically it isn’t a classic opioid like morphine, but it acts like one: 7-OH activates the brain’s mu-opioid receptors, the same receptors targeted by prescription opioids, and the FDA has called concentrated 7-OH an emerging opioid threat. That’s why it can cause tolerance, dependence, withdrawal, and dangerously slowed breathing at high doses, much like other opioids. Learn more about our ibogaine treatment for opiate addiction.
What does 7-OH do?
Like other opioids, 7-OH can relieve pain and cause relaxation, sedation, and euphoria. It can also cause nausea, dizziness, constipation, drowsiness, and slowed breathing, and with regular use the body quickly adapts to it.
Can 7-OH cause dependence?
Yes. With regular use, the brain adapts and you need more to get the same effect (tolerance). Over time the body comes to rely on it, and stopping or cutting back brings withdrawal. Many people end up dosing just to feel normal.
Is 7-OH addictive?
Yes. Concentrated 7-OH can lead to addiction: continuing to use despite harm, losing control over how much and how often you use, and letting work, health, and relationships slide. Dependence is a health problem, not a moral failure, and treatment can help.
What are common 7-OH withdrawal symptoms?
They’re similar to opioid withdrawal: anxiety, restlessness, restless legs, insomnia, sweating, chills, muscle and joint aches, nausea, vomiting, diarrhea, and strong cravings. How severe they are depends on how much and how often you’ve been using. If you’ve been using heavily, don’t stop abruptly on your own; medical support makes withdrawal more manageable.
Are concentrated 7-OH products dangerous?
Yes, they can be. These products are unregulated and their strength varies widely, so it’s easy to take more than you mean to. High doses, especially combined with alcohol, benzodiazepines, or other sedatives, can slow breathing to a dangerous level. Regular use also leads to dependence and difficult withdrawal.
Can 7-OH be combined with alcohol?
No. Mixing 7-OH with alcohol, benzodiazepines, or other sedatives increases the risk of extreme sedation, slowed breathing, and overdose. If someone is hard to wake or breathing slowly, call 911 and give naloxone (Narcan) if you have it.
Where can I learn about treatment?
