Ole Miss Kratom Deaths, Smax Pseudo-DHM Tablets Differ From Traditional Kratom Leaf

Two University of Mississippi students died on September 21, 2026, and investigators reportedly found packages labeled “Smax Pseudo-DHM” tablets in connection with the cases. The question now is whether those tablets contained concentrated or enhanced kratom-related compounds rather than ordinary kratom leaf.

The distinction matters. The U.S. Food and Drug Administration (FDA) has warned that concentrated 7-hydroxymitragynine (7-OH) products can be substantially different from natural kratom leaf. It says 7-OH products sold as tablets, gummies and shots have not been proven safe or effective for any medical use.

One thing is still unresolved. No one has established whether the tablets contributed to the deaths of 18-year-old Aidan Hamilton and 20-year-old Robert Strang. Toxicology and additional laboratory testing were still pending as of September 30, 2026.

What Happened to Aidan Hamilton and Robert Strang in Oxford, Mississippi?

Hamilton and Strang died in separate incidents on September 21. Hamilton was found unresponsive in his University of Mississippi dorm room. Strang was found later that day at an Oxford residence.

Law enforcement said packaged kratom was found during both investigations. They also said there was no confirmed evidence connecting the two deaths and no confirmed evidence that kratom caused either one. A product found near someone who has died does not, by itself, show that the product caused the death.

Investigators then traced purchases of similar products and began looking at the local retail supply chain. According to public reporting on a Lafayette County Metro Narcotics affidavit, they were examining packages labeled Smax Pseudo-DHM and testing the products for controlled substances and other compounds. That reporting did not say the products caused either death.

Why Smax Pseudo-DHM Tablets May Differ From Traditional Kratom Leaf

“Kratom” is used for products that can be chemically very different.

Traditional kratom comes from the leaves of Mitragyna speciosa, a tree native to Southeast Asia. The leaf contains several alkaloids, including mitragynine and much smaller amounts of 7-OH. The FDA’s concern is with products that contain added or enhanced levels of 7-OH. It says these appear as tablets, gummies, drink mixes and shots, and are sold through smoke shops and gas stations, among other places.

Concentrated products raise two practical problems:

• Potency: Extraction can concentrate alkaloids far beyond what a raw leaf contains.
• Unpredictable dosing: These products are not FDA-approved for any medical use, so strength and contents can vary from product to product.

This does not mean every kratom product is the same as a concentrated 7-OH product. It also does not prove what the Smax tablets in this case contained.

What Are Lafayette County Investigators Testing in the Smax Pseudo-DHM Tablets?

Public reporting on the affidavit says preliminary testing detected 7-hydroxymitragynine in some pills. Investigators were arranging further testing for other compounds listed on the packaging. This is reported information, and the affidavit itself was not independently retrieved from an official court repository.

The FDA has already acted against concentrated 7-OH products:

• In June 2025, it issued warning letters to companies selling 7-OH tablets, gummies and shots. It said 7-OH is not lawful as a dietary supplement or conventional food ingredient.
• In December 2025, it seized approximately 73,000 units of concentrated 7-OH products, including tablets and liquid shots.

These actions explain why investigators are looking closely at what is in the Ole Miss tablets. They do not prove what caused either student’s death.

What Happened at Puffs Vape, Tobacco and Beer Store in Oxford?

The investigations led the Lafayette County Metro Narcotics Unit to Puffs Vape, Tobacco and Beer Store on Heritage Drive in Oxford. Officers made a controlled purchase and then obtained a search warrant. The search reportedly led to the seizure of more than 500 units of kratom, along with THC cartridges, gummies and other suspected narcotics.

Yahya Mohamed Mosleh, 51, and Islam Mohamed, 18, were arrested and charged with possession of Schedule I controlled substances with intent to distribute. These are allegations. An arrest or charge is not proof of guilt.

Is Kratom Legal Under Oxford, Mississippi’s Ordinance?

The City of Oxford’s ordinance prohibits the possession, purchase, distribution and sale of kratom and products containing specified compounds, including mitragynine and 7-hydroxymitragynine. Federal and state rules differ from local rules, so a product sold in one town may be banned in another.

What Does the Ole Miss Investigation Mean for Consumers?

A product marketed as “kratom” may not have the same chemical profile as ordinary kratom leaf. The FDA lists liver toxicity, seizures and substance use disorder among the risks of kratom-related products. It has also said deaths have occurred in people who used kratom, but that other substances were often involved and kratom’s contribution was unclear.

Consumers should keep three points in mind:

1. “Natural” does not mean safe. A plant-based label says nothing about potency or purity.
2. Labels are not proof of contents. Don’t rely on packaging to tell you what is in a tablet.
3. Don’t test a product on yourself. If you have a product that may be connected to this investigation, do not consume it to find out what it contains.

If you had an adverse reaction after using a kratom or 7-OH product, seek medical attention. You can also report suspected adverse events to the FDA.

Is There a Lawsuit or Class Action Over the Smax Pseudo-DHM Tablets?

As of September 30, 2026, no consumer class action or settlement involving the Smax Pseudo-DHM products has been identified. The legal activity so far is the criminal investigation into alleged distribution of controlled substances and the separate death investigations. There is no claim form, payment or deadline for people who bought kratom products in Oxford.

For comparison, AllAboutLawyer has covered litigation over other supplements, including the Performix SST Metabolism Supplement Lawsuit, Did You Buy It Without a Required FDA Warning on the Label? and the Balance of Nature $9.95M False Advertisement Class Action Settlement: Who Qualifies, How to File by March 11, 2026. Those are separate matters and are not connected to the Ole Miss investigation.

What Should Someone Who Bought Smax Pseudo-DHM Keep?

There is no Ole Miss-related claim form to complete. If you bought Smax Pseudo-DHM or another suspected 7-OH product, consider keeping:

• The original package and any remaining product
• Photos of the front and back labels
• Lot, batch or expiration information
• Your receipt or transaction record
• The store name and location
• Medical records of any adverse reaction
• Any messages with the retailer or manufacturer

What Happens Next in the Ole Miss Death Investigations?

The next developments will come from laboratory testing and the medical examiner. Investigators need to determine:

1. What compounds were actually in the Smax Pseudo-DHM tablets
2. Whether the tablets contained concentrated 7-OH or other enhanced compounds
3. What substances appear in each student’s toxicology results
4. Whether any substance contributed to either death
5. Whether the two deaths are factually connected
6. Whether more criminal charges are warranted in the retail investigation

Until then, it would be premature to say the tablets caused either death.

Frequently Asked Questions About the Ole Miss Smax Pseudo-DHM Investigation

Did Smax Pseudo-DHM tablets cause the deaths of Aidan Hamilton and Robert Strang?

No finding has established that as of September 30, 2026. Toxicology and product testing were still pending.

Is Smax Pseudo-DHM the same as traditional kratom?

Not necessarily. Investigators described the tablets as kratom-like, while the FDA distinguishes natural kratom leaf from concentrated 7-OH products. The exact composition requires laboratory confirmation.

Is 7-OH the same as natural kratom?

No. 7-OH occurs naturally in kratom in small amounts. The FDA’s warnings focus on products with added or enhanced levels of it.

Is kratom legal in Oxford, Mississippi?

Oxford’s ordinance prohibits the possession, purchase, distribution and sale of kratom and products containing mitragynine and 7-hydroxymitragynine.

Who was arrested in the Puffs Vape, Tobacco and Beer Store investigation?

Yahya Mohamed Mosleh, 51, and Islam Mohamed, 18, were arrested and charged with possession of Schedule I controlled substances with intent to distribute. The charges are allegations only.

Is there an Ole Miss kratom class action lawsuit?

No consumer class action or settlement tied to the Smax Pseudo-DHM investigation had been identified as of September 30, 2026.

Can consumers file a claim for money after buying Smax Pseudo-DHM?

There is no verified settlement claim program. Someone injured by a product may have individual legal options under state law, but that is a separate question from any settlement claim.

Bottom Line on the Ole Miss Smax Pseudo-DHM Investigation

Investigators are now focused on specific Smax Pseudo-DHM tablets and whether they contain concentrated 7-OH or other compounds. The FDA has warned that such products can differ sharply from kratom leaf. But the presence of the tablets does not establish causation, and no final toxicology result had been made public as of September 30, 2026. The criminal case is also separate from any civil claim a consumer or family might pursue later.
