(Press-News.org) Approval of recreational and medical cannabis laws in most U.S. states has allowed individuals to legally obtain cannabis to treat certain medical ailments that had typically been treated with prescription drugs. New research in Health Economics reveals the impact that cannabis laws have had on such traditional prescriptions.
After analyzing prescription drug claims reported by small and large group insurers from 2010–2019 for working-age individuals, investigators found significant reductions in prescription drug claims per enrollee of $34–42 annually in the small group insurance market following recreational cannabis legalization. Net prescription drug claims in these markets were reduced by approximately 6% following recreational cannabis legalization.
The researchers did not observe similar reductions in claims in large group insurance markets. They also did not find strong evidence of an effect of medical cannabis legalization on prescription drug claims in either market.
“We built off prior studies to examine whether declines in prescription drugs among publicly insured populations following cannabis legalization extend to employed individuals,” said corresponding author Rhet A. Smith, PhD, of the University of Texas at El Paso. “We posit the reduction in prescription drug claims in small group insurance markets and not in large group markets suggests important compositional differences across the two markets that may influence cannabis and prescription drug usage across these populations.”

Scientists’ study of white-tailed deer could help control chronic wasting disease
2025-05-21
New research in Wildlife Monographs provides extensive details into the movement of white-tailed deer, with implications for deer management across North America.
For the study, investigators evaluated seasonal activity patterns, home ranges, and habitat selection for nearly 600 white-tailed deer in southwest Wisconsin, USA. The research revealed how an individual deer’s movement and use of space can affect chronic wasting disease transmission.
Chronic wasting disease—a deadly neurological prion ...
More than half of US workers say job insecurity causing stress
2025-05-21
A majority of U.S. workers (54%) said job insecurity has had a significant impact on their stress levels at work, and more than a third (39%) said they are concerned they may lose their job in the next 12 months due to changes in government policies, according to the American Psychological Association’s 2025 Work in America™ survey.
Two-thirds of employed adults (65%) said their company or organization has been affected by recent government policy changes. The survey found that for some, these changes, as well as growing economic ...
A one-pixel camera for recording holographic movies
2025-05-21
A new camera setup can record three-dimensional movies with a single pixel. Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The Kobe University development thus opens the door to holographic video microscopy.
Holograms are not only used as fun-to-look-at safety stickers on credit cards, electronic products or banknotes; they have scientific applications in sensors and in microscopy as well. Traditionally, holograms require a laser for recording, but more recently, techniques that can record holograms with ambient light or light emanating from ...
Biodiversity in Antarctic soils may be greatly underestimated after surprising discovery
2025-05-21
Two important concepts in evolutionary biology, mutualism and altruism, were first made famous by the colorful anarchist prince Peter Kropotkin. He argued that cooperation could be an equally powerful driver of evolution as competition. Crucially, he was inspired by his youth as a geographer in the Russian Far East, where he observed how in particular the harsh climate favored cooperation, both within and between species.
Now, researchers have shown that previously unknown apparent mutualisms allow biodiversity to flourish to ...

Taking the Guesswork out Birdsong Evolution
Biologists from UMass Amherst are the first to comprehensively link bird songs’ pitch and volume, providing insight into bird evolution
AMHERST, Mass. — Biologists at the University of Massachusetts Amherst recently announced that they have released the first broad scale, comparative, fine-grained analysis linking the amplitude, or volume, of a birds’ song to its vocal frequency, or pitch. Though biologists have long wondered whether birds ...
Light-powered artificial muscles for underwater robots with reversible, high-stroke actuation
2025-05-21
A Korean research team has developed a light-powered artificial muscle that operates freely underwater, paving the way for next-generation soft robotics.
The research team—Dr. Hyun Kim at the Korea Research Institute of Chemical Technology (KRICT), Prof. Habeom Lee at Pusan National University, and Prof. Taylor H. Ware at Texas A&M University—successfully developed artificial muscles based on azobenzene-functionalized semicrystalline liquid crystal elastomers (AC-LCEs) that actuate in response to light.
Traditional soft ...
On the origin (and fate) of plants that never bloom
2025-05-21
Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The Kobe University research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin’s suspicion that this strategy might be a path to extinction.
Charles Darwin once remarked, “It is hardly an exaggeration to say that Nature tells us, in the most emphatic manner, that she abhors perpetual self-fertilization.” And yet, Kobe University botanist SUETSUGU Kenji knows of a few islands in Japan where orchids ...
Male bodybuilders face high risk of sudden cardiac death, especially those who compete professionally
2025-05-21
Sudden cardiac death is responsible for an unusually high proportion of deaths in male bodybuilders worldwide with the highest risk among professional bodybuilders, according to research published in the European Heart Journal [1] today (Wednesday).
Sudden cardiac death is when someone dies suddenly and unexpectedly due to a problem with their heart. It is generally rare in young and apparently healthy individuals, but it is often linked to underlying heart conditions.
Researchers say their findings highlight the health risks associated with competitive ...
For galaxies forming stars, it’s not about how much gas there is but where you find it
2025-05-21
Researchers at the International Centre for Radio Astronomy Research (ICRAR) made the discovery about galaxies by studying the gas distribution that helps create stars.
Using CSIRO’s ASKAP radio telescope located at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory, researchers explored the gas distribution in about 1,000 galaxies as part of the WALLABY survey.
Lead author Seona Lee, a PhD student at The University of Western Australia node of ICRAR, said the findings give new insights into how stars ...
Landmark report reveals key challenges facing adolescents
2025-05-20
Poor mental health, rising obesity rates, exposure to violence and climate change are among the key challenges facing our adolescents today, according to a global report.
The landmark report, by experts in adolescent health including from Murdoch Children’s Research Institute (MCRI), has revealed how supporting young people’s health and wellbeing could improve economic, social and public health for generations to come.
The 2025 Lancet Commission on Adolescent Health and Wellbeing found investment in adolescents’ health and wellbeing doesn’t match the scale of the problems faced by young people. Bringing together 44 Commissioners ...
