PISCATAWAY, NJ – Cannabis products containing delta-8 THC have spiked in popularity in recent years, from gummies and brownies to vapes, pre-rolls, and tinctures. These products are frequently marketed as “legal” cannabis and often come in youth-oriented packaging, while lacking clear and consistent cannabinoid-content labels and health warnings to keep consumers safe, according to a new study in the Journal of Studies on Alcohol and Drugs.
Delta-8 THC products—along with other intoxicating “hemp-derived” products—have become widely available in the United States since the passage of the 2018 Farm Bill, which legalized the production of hemp, defined as cannabis plants and their derivatives containing less than 0.3% of delta-9 THC (tetrahydrocannabinol). The 2018 Farm Bill created a perceived legal loophole for cannabinoids made from hemp-derived CBD (cannabidiol), including delta-8 THC.
Delta-8 THC is naturally present in much lower quantities in the cannabis plant than delta-9 THC—the primary intoxicating substance in cannabis, often referred to simply as THC—and is considered less potent than delta-9 THC. However, both compounds have intoxicating effects, and the lack of oversight for delta-8 THC raises concerns for consumer safety. Delta-8 THC products are sold online and in gas stations, head shops, and other specialty stores.
“Some states regulate or ban these products, but, in general, they are subject to fewer regulations than the medical and recreational cannabis you see in licensed dispensaries,” said lead researcher Meagan Robichaud, Ph.D., M.P.H., a Postdoctoral Associate at the Rutgers Institute for Nicotine and Tobacco Studies.
Robichaud, with co-authors in the United States and Canada, studied the packaging for delta-8 THC products to understand how they’re marketed and how key information, such as product strength, is communicated. The researchers analyzed packaging for 140 products submitted by participants in the International Cannabis Policy Study (principal investigator: David Hammond, Ph.D., University of Waterloo, Ontario, Canada), which collected photos of delta-8 THC products used by the participants during two survey waves, in 2021 and 2022.
Packaging is more than just a container—it is a way to communicate potential product risks and instructions for safe use. “The lack of clarity and consistency in the cannabinoid content labels—in addition to the youth-appealing marketing on some packages—really stood out to me,” noted Robichaud. “This was especially true for delta-8 THC vape products.”
For example, packaging for vapes often mentioned milligrams of delta-8 THC without specifying the total product weight, so the concentration (milligrams per gram) wasn’t clear. The amount of delta-8 THC in ingestible products was high: Over half the edibles claimed to have at least 25 mg per piece. The legal limit for delta-9 THC, for comparison, is 10 mg.
“I would caution consumers about the serving sizes of some of these products,” said Robichaud. “One product in our study contained five servings in a single gummy. This can easily lead to people consuming more intoxicating cannabinoids than intended and potentially increase the risk of adverse reactions.”
Many packages are designed to appeal to younger consumers, often featuring bright colors, fruity or sweet flavor descriptors, and references to music and partying. Words such as organic, natural, and vegan are also common and can make these products appear healthful. Lacking effective regulation, such marketing appeals can mask the risks of delta-8 THC while potentially overstating its benefits—something consumers need to know to stay vigilant, and stay safe.

Bringing diabetes treatment into focus
2026-03-12
Kyoto, Japan -- In type 1 diabetes, the immune system starts to destroy insulin-producing beta cells in the pancreas. Progressive loss of these cells destabilizes the body's glucose levels and drives the course of the disease, so preserving or restoring beta cell mass is a central treatment goal.
New therapies aimed at preserving or increasing beta cell mass are advancing rapidly, but a noninvasive, direct measurement of this mass, and how much has been preserved or restored in interventions, is still lacking in routine clinical ...
Iowa-led research team names, describes new crocodile that hunted iconic Lucy’s species
2026-03-12
More than 3 million years ago, when our ancient ancestors embodied by the iconic Lucy were roaming the African landscape, they would have feared a big, bad crocodile with a prominent lump on its head, patiently lurking in rivers and lakes to attack them.
That crocodile is a new species, a research team led by the University of Iowa has determined. In a new study, published on March 12 in the Journal of Systematic Palaeontology, the researchers describe the species and give it a name: Crocodylus lucivenator, or Lucy's hunter.
The name seems quite appropriate. The ancient reptile lived between 3.4 million to 3 million years ago, overlapping the time period and ...
One-third of Americans making financial trade-offs to pay for healthcare
2026-03-12
WASHINGTON, D.C. — March 12, 2026 — About one in three U.S. adults, the equivalent of over 82 million Americans, report having made at least one daily life trade-off in the past year to pay for healthcare expenses, according to new research released today from the West Health-Gallup Center on Healthcare in America. The most common actions taken are prescription rationing and non-adherence (15%) and borrowing money (15%).
Unsurprisingly, the financial strain is most prevalent among households earning ...
Researchers clarify how ketogenic diets treat epilepsy, guiding future therapy development
2026-03-12
Published today in The Lancet Neurology, a new review from the University of Colorado Anschutz in collaboration with UT Southwestern Medical Center, offers the latest scientific explanations for why ketogenic diets reduce seizures in people with epilepsy.
The paper brings together insights from both laboratory discoveries and real‑world patient outcomes, showing that ketogenic diets do far more than reduce seizures. The review outlines how these strict high-fat, low carbohydrate diets strengthen the brain’s energy systems, reduce inflammation and protect neurons - providing therapeutic benefits that many current medications are not yet able to achieve.

Island birds reveal surprising link between immunity and gut bacteria
2026-03-12
Scientists at the University of East Anglia (UK) have uncovered a hidden link between gut health and the immune system – all thanks to a tiny island bird.
Researchers studied the Seychelles warbler, a small songbird found on Cousin Island in the Seychelles.
They collected the birds’ poo to analyse their gut bacteria – and found that their immune genes influence which gut microbes thrive.
They say their work sheds light on how animal immune systems and communities of beneficial gut bacteria evolve together - including in humans.

Further evidence of developmental risks linked to epilepsy drugs in pregnancy
2026-03-11
Findings published by The BMJ today reinforce previous research linking use of the antiseizure drug valproate during pregnancy to neurodevelopmental disorders such as ADHD and autism in children, and indicate no substantial risk for several other antiseizure drugs including levetiracetam and lamotrigine.
However, the researchers say continued monitoring of the few signals - possible associations between a medicine and an unintended side effect - that emerged (eg, for zonisamide) will be important.
Antiseizure drugs are ...
Cosmetic procedures need tighter regulation to reduce harm, argue experts
2026-03-11
The rise in invasive cosmetic procedures demands tighter regulation, better consumer protection, and greater awareness to protect patient safety and reduce cosmetic tourism, argue experts in The BMJ today.
The global market for cosmetic procedures is growing rapidly and is projected to exceed $180bn by 2033, note Danielle Griffiths at the University of Liverpool and colleagues.
Invasive cosmetic procedures typically involve the insertion of instruments or equipment into the body (eg, tummy tucks and breast augmentation), while non-surgical procedures are minimally invasive (eg, botox and dermal fillers), they ...
How chaos theory could turn every NHS scan into its own fortress
2026-03-11
Fresh research from the University of East Anglia (UEA) could transform how the NHS protects patients’ medical images from cyber‑attacks.
Computer scientists have developed a breakthrough way to encrypt medical images such as X‑rays, CT scans and MRIs, keeping them secure even if hospital networks are breached.
Medical imaging systems have been repeatedly identified as weak points, with many relying on legacy protocols that were never designed to be exposed to the internet, making image‑level encryption an urgent priority.
Developed ...
