In the first 90 days of concurrent opioid and benzodiazepine use, the risk of opioid-related overdose increases five-fold compared to opioid-only use among Medicare recipients, according to a new study from the University of Pittsburgh School of Pharmacy.
Health care insurers including Medicare, Medicaid and major private insurers have not done enough to combat the opioid epidemic, suggests a study led by researchers at Johns Hopkins Bloomberg School of Public Health.
An analysis of Medicare claims data suggests chronic opioid use in US counties corresponded with support for Republican Donald Trump in the 2016 presidential election, with much of the correlation explained by socioeconomic factors.
Opioids are powerful painkillers that act on the brain, but they have a range of harmful side effects including addiction. Researchers from the Max Planck Institute of Biochemistry in collaboration with researchers from the Medical University of Innsbruck, Austria, University of Innsbruck, and the Lewis Katz School of Medicine at Temple University, have developed a tool that gives deeper insights into the brain's response to opioids.
In 2014, California voters approved Proposition 47, which reclassified drug possession offenses from felonies to misdemeanors, and in the process reduced the state's prison and jail populations. Now, a study out of UC San Francisco has quantified the effects of the ballot measure, which was at the leading edge of a national movement to reduce incarceration rates and change the criminal justice approach to substance use disorders.
Changes in a brain signalling system contribute to the development of alcohol addiction-like behaviours in rats, according to a new study led by researchers at Linköping University, Sweden. The findings, to be published in Science, indicate a similar mechanism in humans.
Cannabis use may be decreasing among teens, but a new study showed that American adults have increasingly used cannabis daily since 2007. The study found that nondaily cannabis use decreased among those aged 12 to 25 and 35 to 49 before 2007, and increased among all adults after 2007, particularly among adults 26 to 34.
Survivors of opioid overdose are at great risk of dying in the year after overdose, but the deaths are not always caused by drug use, a new study reveals. In addition to succumbing to drug use, survivors were much more likely to die from respiratory diseases, viral hepatitis, and suicide.
A new Drug Testing & Analysis study reveals that measuring levels of ethyl sulfate (EtS), a metabolite of ethanol, in the hair can be used to assess alcohol consumption.
Adults who survive an opioid overdose are at high risk of dying during the year after the incident of substance use-associated diseases, suicide and other medical conditions.
