Eight months after federal health officials warned that a kratom-derived substance could trigger “the next wave of the opioid epidemic,” 7-Hydroxymitragynine, known as 7-OH, remains on the shelves of gas stations, vape shops and convenience stores across most of the country.

For people already fighting opioid addiction, experts warn this legal loophole is opening a dangerous new front.

The Opioid Crisis Gets a New Face

A Midwest businessman who spent two decades battling prescription pill and heroin addiction thought he had found something harmless. He picked up 7-OH pills at a local smoke shop on his way to work.

“How bad could this really be?” he recalled thinking.

The answer nearly destroyed him. The substance triggered what he described as a full opioid effect and the withdrawal that followed was worse than quitting intravenous heroin.

He eventually required a rigorous medical detox program and estimates the habit cost him roughly $200 a day at its peak.

“It was harder to get off of than shooting IV heroin,” he said. “Much harder.”

His story is no longer unusual. As fentanyl and heroin addiction have dominated headlines for a decade, 7-OH has quietly built its own user base, one that shops in plain sight.

What Is 7-OH and Why Does It Matter for Opioid Abuse

7-OH is a highly concentrated, semi-synthetic derivative of kratom, a tropical plant native to Southeast Asia. While natural kratom leaves contain less than 1% of 7-OH by composition, concentrated commercial products can be formulated with up to 98% 7-OH.

It’s sold as gummies, tablets, drinkable shots, and candy. According to the FDA, 7-OH binds to the mu-opioid receptor, meaning it is scientifically classified as an opioid, carrying all the associated risks such as respiratory depression, dependence and narcotics overdose.

Researchers at Johns Hopkins University found that 7-OH binds to mu-opioid receptors with 14 to 22 times the affinity of morphine. Unlike prescription opioids or heroin, it requires no prescription and no back-alley contact. It requires only a trip to the nearest gas station.

The Federal Standstill on 7-OH

In July 2025, during a joint press conference, the FDA formally recommended to the DEA that 7-OH be classified as a Schedule I controlled substance under the Controlled Substances Act, the same classification as heroin.

FDA Commissioner Dr. Marty Makary warned reporters that concentrated, synthetic 7-OH “may be the fourth wave of the opioid epidemic.” HHS Deputy Secretary Jim O’Neill called its widespread availability “a recipe for public health disaster.”

Yet as of early 2026, the DEA has not completed the rulemaking process to make the scheduling effective, meaning 7-OH remains unscheduled at the federal level. The DEA’s review includes a public comment period that legal analysts say could stretch for months or longer.

Public health officials are drawing direct parallels between 7-OH’s rise and the early days of the fentanyl crisis. Opponents of the substance note that, like fentanyl, 7-OH is significantly more potent than morphine and carries serious risks of respiratory depression at high doses.

Fatal overdoses linked to concentrated 7-OH products have been confirmed in Los Angeles County, where three otherwise healthy adults between the ages of 18 and 40 died. Poison control calls related to kratom and 7-OH surged to 192 in Texas alone by August 2025.

Meanwhile, the Washington Poison Center reported kratom exposures surged to 1,800 by early August 2025, with approximately one-third of calls specifically involving 7-OH extracts, a dramatic increase from the 330 to 1,400 annual calls seen between 2015 and 2024.

Critically, 7-OH withdrawal can last significantly longer than traditional opioid withdrawal, potentially up to three months, complicating treatment and increasing relapse risk.

States Act While Washington Waits

With no federal ban in place, a patchwork of state laws has emerged. Florida, Louisiana, Mississippi and Colorado have all banned synthetic 7-OH, and Alabama, Arkansas, Indiana, Vermont and Wisconsin previously banned kratom or its derivatives.

Florida alone has reported the removal of more than 17,000 packages of concentrated 7-OH since its ban took effect.

In December 2025, the FDA, working with the Department of Justice and U.S. Marshals Service, seized approximately 73,000 units of 7-OH products from three Missouri firms.

Not everyone agrees that prohibition is the right path. Dr. Jeff Singer of the Cato Institute argues that scheduling 7-OH will simply push use underground, particularly among chronic pain patients and veterans who use it to manage symptoms.

The man who survived 7-OH addiction disagrees firmly, believing mothing like that should be available at a gas station.

Naloxone Works But Multiple Doses May Be Needed

For those in active 7-OH use or supporting someone who is, harm reduction tools remain critical. The Los Angeles County Department of Public Health confirmed that naloxone (Narcan) can reverse 7-OH toxicity, though repeated doses may be required due to its potency.

Naloxone is available without a prescription at most pharmacies in the United States. If you or someone you know is using 7-OH or any opioid, carrying naloxone is a potentially life-saving step.
