OKC Doc Warns 'Gas Station Heroin' Shots Are Hooking Workers Overnight

An Oklahoma City addiction specialist is sounding the alarm about over-the-counter energy supplements sold at gas stations and smoke shops that contain powerful, unscheduled opioid compounds such as 7-hydroxymitragynine (7-OH) and a lab-made derivative known as MGM-15. The doctor says these products can trigger rapid physical dependence and punishing withdrawal, and that some manufacturers appear to be reformulating to skirt recent state limits on concentrated kratom alkaloids. The warning comes as state and federal agencies ramp up scrutiny of concentrated kratom derivatives.

Dr. Robert Westcott, medical director of Medical Therapy Associates in Oklahoma City, has treated patients who picked up these so-called energy boosters and then became unable to work because of severe withdrawal and opioid-like dependence, as reported by Journal Record. He told the outlet that product labels often list vague ingredients or cryptic shorthand such as "MGM" or "DHM" on the packaging, terms he says are commonly used to hide high-potency alkaloids. According to the report, some patients ended up needing medication-assisted treatment just to stabilize.

Federal regulators have already moved against concentrated 7-OH products: the U.S. Food and Drug Administration announced coordinated seizures of thousands of units and in 2025 recommended review and scheduling of certain concentrated 7-OH preparations because of their opioid-like effects, the agency said in a bulletin, according to the FDA.

Laboratory studies help explain the urgency. Research has found that 7-hydroxymitragynine binds opioid receptors far more strongly than most kratom alkaloids and in some preclinical work has been reported to be roughly 7–13 times as potent as morphine. A 2014 pharmacology study of mitragynine derivatives found MGM-15 and related compounds produced antinociceptive effects several times higher than morphine in mouse assays, in some measures approaching tens of times morphine's potency, which researchers say raises the risk that small retail doses could deliver unexpectedly strong opioid effects, according to the Journal of Pharmacology and Experimental Therapeutics.

Why employers and parents should care

Standard workplace immunoassay drug panels, including typical 5- and 10-panel screens, do not routinely detect mitragynine, 7-OH, or MGM-type derivatives, so use can fly under the radar unless a clinician or employer specifically requests specialized LC-MS/MS testing, laboratory guidance shows, according to Quest Diagnostics. That blind spot creates safety concerns for employers, schools and families when someone begins to experience dependence or acute withdrawal after using a product marketed as a harmless supplement.

How to spot risky products and where to get help

Clinicians quoted in local reporting advise steering clear of products labeled with terse ingredient codes like "MGM" or "DHM," vague phrases such as "kratom alkaloids," or marketing language like "Florida Compliant" and "Full-Spectrum Extract," which they say are often used to promote concentrated, chemically altered alkaloids. If someone develops intense withdrawal or a sudden loss of function after taking one of these items, local clinicians report that medication-assisted treatment is being used to stabilize patients and manage opioid-type withdrawal symptoms, according to Journal Record.

State rules and enforcement

Oklahoma moved in late 2025 to restrict synthetic kratom alkaloids and cap concentrated 7-OH levels in retail products. Local clinicians and clinics say vendors are already tweaking formulas to keep items on shelves, a cat-and-mouse shift that complicates enforcement and public-health messaging. At the federal level, the FDA has signaled enforcement through seizures and public warnings about concentrated 7-OH products, creating a patchwork of actions that often leaves frontline clinicians and employers to handle the immediate health fallout.

Health officials and addiction specialists say the practical takeaway is straightforward: treat these energy shots like any other potent opioid risk. If someone appears to be struggling after taking an over-the-counter energy supplement, seek medical care quickly and tell clinicians exactly what product was used so labs can order targeted testing and offer appropriate medication-assisted treatment.
