Hands holding 7-hydroxymitragynine tablets and a kratom drink, products linked to the “gas station opioid” raising concern among Flint health officials.

Flint Officials Warn ‘Gas Station Opioid’ Fuels New Addicts

At a Glance

  • What’s happening: Flint health officials report rising use of a “gas station opioid” — 7-hydroxymitragynine (7-OH) — sold as tablets, gummies, and shots in smoke shops and gas stations.
  • Why it’s risky: 7-OH is a potent opioid-like compound (stronger than kratom leaf) linked to sedation, slowed breathing, overdose, tolerance, and withdrawal.
  • Overdose response: Naloxone (Narcan) can reverse 7-OH overdoses; families should carry naloxone and call 911 for suspected overdose.
  • Regulatory moves: In July 2025, the FDA issued warning letters and recommended scheduling 7-OH under the Controlled Substances Act; Michigan communities are debating local restrictions.
  • Who’s affected: Many first-time opioid users tried it for sleep, anxiety, pain, or “energy,” assuming supplement labels meant it was safe.
  • Treatment works: Evidence-based care—buprenorphine or methadone, counseling, and peer support—is recommended; MDHHS, SAMHSA, and Genesee County groups provide free naloxone and referrals.
  • How Nova helps: Nova Recovery Center offers medical detox, personalized treatment plans, relapse-prevention tools, and education to address 7-OH dependence and support long-term recovery.

Health and treatment officials in Flint report a steady rise in people using a substance often called a “gas station opioid.” They say many patients first bought it at smoke shops, corner stores, or gas stations because it was displayed as a legal supplement.

Clinicians describe people arriving in withdrawal, asking for help to stop, or needing naloxone after an overdose. They add that the pattern can look different from recent fentanyl cases because many patients thought they were taking a legal product rather than an illicit opioid.

Local coverage across Michigan mirrors these warnings and notes that naloxone can reverse overdoses tied to the product.

What 7‑OH is and how it differs from kratom

Officials say the product drawing the most concern is 7‑hydroxymitragynine—commonly shortened to 7‑OH. It is a potent opioid‑like compound related to kratom, but it is much stronger than the alkaloids found in unprocessed kratom leaf. Companies sell 7‑OH in tablets, gummies, drink mixes, shots, and canned drinks, often alongside labels that emphasize “kratom” or “botanical extract.”

Regulators emphasize that no 7‑OH product is approved for any medical use. In July 2025, the FDA recommended that the DEA place certain 7‑OH products under federal control because of their abuse potential and the growing number of adverse events.

Health risks and signs of use

Medical toxicologists and poison centers link 7‑OH to sedation, slowed breathing, and overdose at high doses. People who take it regularly can develop tolerance and dependence, then experience withdrawal when they try to stop.

Emergency clinicians report that naloxone (Narcan) can reverse overdoses involving 7‑OH, which is consistent with how opioids act on the brain. Families and providers also describe anxiety, nausea, muscle aches, and insomnia during withdrawal. These risks are the reason federal and state agencies are issuing frequent public advisories.

Response from regulators and lawmakers

Regulators have begun to act. In mid‑July 2025 the FDA issued warning letters to firms marketing 7‑OH products, citing unlawful claims and safety concerns. Soon after, the agency recommended scheduling 7‑OH under the Controlled Substances Act, a step that would restrict manufacturing and sales.

Local governments in Michigan have debated retail limits and other rules, while state legislators have discussed measures aimed at kratom‑related products and derivatives. News outlets in Metro Detroit report active proposals to regulate or restrict 7‑OH at the community level.

What’s driving local concern

Providers in the Flint area say many people who had never used opioids before tried these products for sleep, anxiety, pain, or “energy.” Because they are sold as supplements, some buyers assume they are safer than illegal opioids. Officials also warn that concentrated, lab‑made 7‑OH is not the same as kratom leaf, and that labels can blur this difference. Public health experts caution that self‑treating with these products can lead to dependence, more severe withdrawal, and—in some cases—a transition to other opioids, complicating recovery.

Treatment and harm‑reduction steps

Clinicians recommend the same evidence‑based care used for other opioid use disorders: medications such as buprenorphine or methadone, counseling, and peer support. Families are urged to keep naloxone on hand and to call 911 for any suspected overdose. In Genesee County, community groups host free naloxone trainings, and Michigan’s health department provides no‑cost naloxone and referral pathways to treatment. Residents can find state‑funded services through MDHHS and national resources through SAMHSA.

What to watch next

A federal scheduling decision could determine how 7‑OH products are made, labeled, and sold across the United States. Until then, Flint health and treatment officials say they will keep tracking overdoses, hospital visits, and retail availability, and will continue outreach with schools and neighborhood groups. They stress that early awareness helps prevent harm and that help is available for anyone seeking recovery.

Frequently Asked Questions: Gas Station Opioids (7‑OH, Kratom, Tianeptine) in Michigan

A: The phrase refers to unapproved products sold in gas stations and smoke shops that have opioid‑like effects. Two common examples are tianeptine (often marketed as an “energy” or “focus” product) and concentrated 7‑hydroxymitragynine (7‑OH), a potent kratom‑related compound. Both have raised safety concerns among health officials.

No. 7‑OH is a kratom‑related alkaloid found naturally only in trace amounts; concentrated 7‑OH products are much more potent than typical kratom leaf, with stronger activity at μ‑opioid receptors.

7‑OH is not an approved drug, food additive, or dietary supplement ingredient. In 2025 the FDA issued warning letters and recommended scheduling 7‑OH under the Controlled Substances Act; federal and state actions are evolving.

As of mid‑2025, kratom remained legal in Michigan, while lawmakers pursued measures to regulate it in response to safety concerns and incidents linked to derivative products. Always check current statutes, which can change.

Officials cite addiction, withdrawal, and overdose risks—especially with concentrated 7‑OH products marketed as “botanicals”—and a rise in adverse events from tianeptine sold as “energy” or “cognitive” supplements.

Evidence from clinical reports and public‑health guidance indicates naloxone can reverse opioid‑like respiratory depression from kratom‑related exposures and tianeptine; several agencies now advise administering naloxone in suspected 7‑OH cases as well. Call 911 immediately after giving naloxone.

Reported risks include sedation, respiratory depression, seizures, and overdose, especially at high doses or when combined with alcohol or other sedatives.

Withdrawal may involve anxiety, nausea, muscle aches, insomnia, agitation, and other symptoms. Severity varies with dose and duration of use.

Laboratory and animal studies show 7‑OH is significantly more potent at μ‑opioid receptors than mitragynine, helping explain stronger effects and higher risk at equal amounts.

The FDA states 7‑OH is not lawful as a dietary supplement or food additive and has not been approved as a medication. Tianeptine is not FDA‑approved in the U.S., despite being marketed in some stores.

In 2025 the FDA warned firms marketing 7‑OH products and recommended scheduling 7‑OH; the agency has also issued multiple consumer warnings about tianeptine products sold as supplements.

Yes. Bills have been introduced to regulate kratom amid concerns tied to derivative products like 7‑OH; coverage continues in state media.

Call 911 immediately. If available, administer naloxone and monitor breathing until help arrives; multiple doses may be needed. Public‑health advisories recommend naloxone in suspected 7‑OH or tianeptine events.
