FDA Wants 7-OH Kratom Derivative Classified as Illegal Drug

By Crystal Lindell

The U.S. Food and Drug Administration is taking the initial steps to make the kratom derivative 7-OH an illegal Schedule One controlled substance – a classification that would put it in the same category as heroin. 

The FDA announced its plan this week, saying it was targeting 7-hydroxymitragynine (7-OH), an alkaloid that occurs naturally in kratom in trace amounts. Some kratom vendors are selling concentrated synthetic versions of 7-OH to boost its potency as a pain reliever and mood enhancer.

The FDA claims it is “not focused on natural kratom leaf products,” but in a report released as part of the announcement, the agency said it still “has concerns about the safety of kratom products more broadly."

The FDA said it is focused on 7-OH for now "because it is a substance with potent mu opioid agonist properties and significant abuse liability." The agency recently warned 7 companies to stop selling kratom products with concentrated levels of 7-OH.

“Vape stores are popping up in every neighborhood in America, and many are selling addictive products like concentrated 7-OH. After the last wave of the opioid epidemic, we cannot get caught flat-footed again,” said FDA Commissioner Marty Makary, MD.

“7-OH is an opioid that can be more potent than morphine. We need regulation and public education to prevent another wave of the opioid epidemic.”

To be clear, neither kratom or 7-OH are derived from poppy plants and they are not opioids. Kratom leaves come from Mitragyna speciosa, a tropical tree native to southeast Asia that belongs in the same botanical family as coffee. 

But because 7-OH acts on opioid receptors in the brain, the FDA claims it is essentially an opioid, a questionable argument the agency has also made about kratom itself. If that were true, you could say nicotine, caffeine, and even cow’s milk are opioids, because they also bind to opioid receptors. 

Curiously, the FDA’s news release did not mention any cases of someone overdosing on 7-OH or being harmed by it – even though the agency’s Adverse Event Reporting System has recorded two deaths and 13 other cases involving 7-OH. However, because of “ambiguity about the contributory role of 7-OH,” the FDA is downplaying the significance of those adverse events.

The only justification offered by the FDA for why 7-OH needs to be classified as a Schedule One controlled substance is the assertion that it is “increasingly recognized as having potential for abuse.” 

Jeff Smith, national policy director at Holistic Alternative Recovery Trust, a kratom advocacy group, told The New York Times the FDA has no data to support taking emergency action on 7-OH.

“If 7-OH posed the kind of urgent danger that would justify emergency action, evidence would have been presented,” Smith said. “It was not.”

Kirsten Elin Smith, a Johns Hopkins University assistant professor who studies kratom, told The Times that she was initially very concerned about 7-OH when it began showing up in kratom products. She has since changed her perspective. 

“If you had asked me a year ago, I would have said this is evil,” Smith said. “At this point I’m a little more equivocal."

The announcement from the FDA is only the first step in what can be a long process for classifying a substance under the Controlled Substances Act. The move requires the Drug Enforcement Administration to publish a notice in the Federal Register, present its evidence, and then allow for a public comment period.  

The DEA tried that with kratom in 2016, at the request of the FDA, but then backed down after a public outcry and opposition from Congress. A top federal health official later said the FDA's scheduling request was based on “embarrassingly poor evidence & data.”

FDA Warns Alkaloid in Kratom Extracts ‘May Be Dangerous’

By Pat Anson

The Food and Drug Administration is cracking down again on the kratom industry, by sending warning letters to 7 kratom vendors about illegally marketing a dietary supplement.

At issue is an alkaloid in kratom called 7-hydroxymitragynine -- known as 7-OH -- which relieves pain, improves mood, increases energy, and has opioid-like properties. 7-OH occurs naturally in kratom, but is present in only trace amounts.

Too boost its potency, some vendors are selling kratom gummies, tablets and extracts with concentrated levels of 7-OH, which the FDA says “may be dangerous.”

“7-OH is not lawful in dietary supplements and cannot be lawfully added to conventional foods. Additionally, there are no FDA-approved drugs containing 7-OH, and it is illegal to market any drugs containing 7-OH. Consumers who use 7-OH products are exposing themselves to products that have not been proven safe or effective for any use,” the agency said in a press release.         

Warning letters were sent this month to Shaman Botanicals, My Smoke Wholesale, Relax Relief Rejuvenate Trading, Thang Botanicals, Royal Diamond Imports, Hydroxie, and 7Tabz Retail. The companies were given 15 business days to respond or take corrective action.

While some of the vendors have removed 7-OH products from their websites, others continue to sell them. Hydroxie, for example, still accepts orders for chewable tablets containing up to 30mg of 7-OH on its website. There are no explicit warnings about the tablets on the webpages where they are advertised, but Hydroxie cautions consumers about 7-OH on its “Warnings” page.     

“This product contains concentrated alkaloids. The potency is significantly greater than raw leaf,” Hydroxie says. “Levels of 7-OH in these tablets are extremely concentrated. Do not use this product without first consulting a doctor about this alkaloid to ensure it is safe for you.”

Kratom has been used for centuries in southeast Asia as a natural stimulant and pain reliever, but only in the past decade has it become widely used in the United States — over the objections of the FDA, which tried unsuccessfully to ban kratom by listing it as a controlled substance.

It’s rare for someone to have an adverse reaction to natural kratom leaf, but people who consume concentrated extracts have been hospitalized or experienced overdoses.

Recently, former CDC Commissioner Robert Redfield, MD, called for kratom products containing elevated levels of 7-OH to be taken off the market.

“What we’re seeing with the compound 7-hydroxymitragynine is a textbook case of how manufacturers exploit regulatory gaps to create products that are, in essence, unregulated pharmaceuticals,” Redfield said.

“To put this in perspective: natural kratom contains less than 0.01 percent 7-hydroxymitragynine. These synthetic products contain concentrations up to 150 times higher. This is not botanical kratom — this is pharmaceutical-grade opioid chemistry operating without oversight.”

Two deaths and three other serious cases involving 7-OH mitragynine have been reported on the FDA’s Adverse Events Reporting System since 2023.  Of the three adverse events reported so far in 2025, one was considered life threatening. Another case resulted in a person being hospitalized. No other details are available.

When used cautiously, kratom advocates say 7-OH is a highly effective pain reliever and safer alternative to opioid medication.

“7-OH can be an invaluable harm reduction tool that should remain an option for the hundreds of thousands of consumers that rely on it,” the Holistic Alterative Recovery Trust (HART) said in a statement.

“HART strongly supports robust regulation and is pursuing legislation federally, and in the states, to mandate that all 7-OH products are manufactured safely, are marketed transparently, and are kept out of the hands of children.”
