Teen vaping is changing fast — and not in a good way. A large national study found that more adolescents are vaping THC, CBD, and especially synthetic cannabinoids, which are often unregulated and far more dangerous. Even more troubling, many teens don’t know what’s in their vape pens at all. Researchers also found that girls are now more likely than boys to vape these substances. As these mysterious and risky chemicals gain popularity, scientists are sounding the alarm about the urgent need for better education, regulation, and awareness.

Teens are being misled by cannabis edibles dressed up like health foods. Bright colors, fruit imagery, and words like vegan make these products look fun, natural, and safe even when they re not. A WSU study warns that this could increase the risk of underage use and urges new packaging rules based on what actually appeals to teens.

Cannabis use among older Americans has climbed dramatically, with 7% of adults 65 and older now reporting recent use. This rise isn't just in numbers but also in diversity older users today are more likely to be women, college-educated, and higher-income. Researchers suggest legalization and growing social acceptance are contributing factors, especially in states with medical marijuana laws. The trend is especially notable among those with chronic illnesses, raising both opportunities and concerns for medical professionals trying to balance symptom relief with the complexities of aging.

As psychedelics gain traction as potential treatments for mental health disorders, an international study stands to improve the rigor and reliability of clinical research.

Marijuana use among older adults in the US has reached a new high, with 7 percent of adults aged 65 and over who report using it in the past month, according to a recent analysis.

Close to five million smuggled seahorses worth an estimated CAD$29 million were seized by authorities over a 10-year span, according to a new study that warns the scale of the trade is far larger than current data suggest. The study analyzed online seizure records from 2010 to 2021 and found smuggling incidents in 62 countries, with dried seahorses, widely used in traditional medicine, most commonly intercepted at airports in passenger baggage or shipped in sea cargo.

A new study finds that chronic cannabis use -- whether it's smoked or consumed in edible form -- is associated with significant cardiovascular risks.

Researchers have identified a remarkably small but critical piece of genetic code that helps determine how brain cells connect, communicate, and function. The discovery not only deepens our understanding of how the brain's wiring is built but may also explain the origins of several neurological and psychiatric conditions.

If you've ever regretted ordering a spicy meal, take note: A new study identifying molecules that suppress the heat of chili peppers hints at the possibility of adapting these compounds into an 'anti-spice' condiment for food that's too fiery to eat. The research helps explain differences in chili pepper pungency, or spiciness, by identifying three compounds in a range of pepper samples that chemical analysis predicted, and study participants on a tasting panel confirmed, are linked to lower heat intensity.

Neuroscientists have discovered that the brain uses a dual system for learning through trial and error. This is the first time a second learning system has been identified, which could help explain how habits are formed and provide a scientific basis for new strategies to address conditions related to habitual learning, such as addictions and compulsions. The study in mice could also have implications for developing therapeutics for Parkinson's.

A recent study marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells. As a proof-of-concept, the authors of the study asked the AI to design synthetic fragments which activate a gene coding for a fluorescent protein in some cells while leaving gene expression patterns unaltered. They created the fragments from scratch and dropped them into mouse blood cells, where the sequence fused with the genome at random locations. The experiments worked exactly as predicted and pave the way for new strategies to give instructions to a cell and guide how they develop and behave with unprecedented accuracy.

Groundbreaking device instantly detects dangerous street drugs, offering hope for harm reduction A portable device that instantly detects illicit street drugs at very low concentrations, thereby highlighting the risks they pose. The device has the potential to address the growing global problem of people unknowingly taking drugs that have been mixed with undeclared substances, including synthetic opioids such as fentanyl and nitazenes.

Researchers are investigating how the legal supply of cannabis affects consumption and mental health among participants. In a first academic publication, the study team has now reported on the direct comparison of the substance's legal versus illegal procurement.

A systematic evidence review finds that consuming cannabis while pregnant appears to increase the odds of preterm birth, low birth weight and infant death.

A new approach to drug design can deliver medicine directly to the gut in mice at significantly lower doses than current inflammatory bowel disease treatments. The proof-of-concept study introduced a mechanism called 'GlycoCaging' that releases medicine exclusively to the lower gut at doses up to 10 times lower than current therapies.

Childhood trauma significantly increases the likelihood of engaging in harmful alcohol consumption, smoking and illicit drug use, by the age of 18.

Researchers found that Mindfulness-Oriented Recovery Enhancement (MORE) can help rewire the brain's response to natural healthy pleasure, leading to reduced opioid cravings. The findings suggest that MORE could be a promising tool in the fight against opioid use disorder.

About 25% of 7350 patients hospitalized for scooter-related injuries between 2016 and 2021 were using substances such as alcohol, opioids, marijuana and cocaine when injured. The findings underscore the urgent need to strengthen safety regulations, enforce helmet use, and reduce substance use among scooter riders.

Prions transmit their abnormally folded shape onto other proteins. Researchers designed a synthetic fragment of the tau protein that exhibits prion-like behavior. Misfolded tau proteins are the hallmark of many neurodegenerative diseases, including Alzheimer's disease and frontotemporal dementia. Study revealed crucial role of water organization in the tau misfolding process.

Ketamine addiction is linked to high levels of physical health problems and psychological consequences, with nearly half of those affected not seeking support or treatment, new research has revealed.
