A genome-wide association study has identified a new genetic alteration in European-Americans with opioid dependence. The study, published in Biological Psychiatry, included over 3,000 opioid-exposed people. The new findings provide insight into the biological origins of opioid dependence, which has become an epidemic of historical proportions in the US, driven by dangerous use of prescription painkillers and heroin.
Legalizing medical marijuana has not increased recreational use of the substance among US adolescents, according to a new study. For now, there appears to be no basis for the argument that legalizing medical marijuana has increased teens' use of the drug. The researchers analyzed the results of eleven separate studies dating back to 1991. No significant changes, increases or decreases, occurred in adolescent recreational use following enactment of medical marijuana laws.
Two papers published today look at the current evidence of the effects of medical marijuana laws and conclude there is little support that such laws increase recreational marijuana use among adolescents or reduce opioid overdose deaths.
Drug addiction continues to plague vast numbers of people across the world, destroying and ending lives, while attempts to develop more effective pharmaceutical addiction treatments continue. Scientists now report in the Journal of the American Chemical Society the development of a potent new medicine to fight addiction, which might also be an effective treatment for epilepsy and other conditions.
Researchers can now remove the anxiety drug Diazepam from recycled water and wastewater, using low-cost titanium dioxide nanofibers. First marketed as Valium, Diazepam is available in hundreds of brands. The drug is one of three benzodiapezines in the World Health Organisation list of essential medicines, but is also widely abused as an addictive prescription drug. In cities running out of water, removing pharmaceuticals from wastewater in a simple, low cost way is becoming a priority.
According to a new study, screening all adults for hepatitis C (HCV) is a cost-effective way to improve clinical outcomes of HCV and identify more infected people compared to current recommendations. Using a simulation model, researchers from Boston Medical Center, Massachusetts General Hospital (MGH) and Stanford University found that this expanded screening would increase life expectancy and quality of life while remaining cost-effective.
A new study shows that public health and public safety agencies established local, collaborative programs in Massachusetts to connect overdose survivors and their personal networks with addiction treatment, harm reduction, and other community support services following a non-fatal overdose.
Scientists at The Scripps Research Institute (TSRI) have achieved a major milestone toward designing a safe and effective vaccine to both treat heroin addiction and block lethal overdose of the drug.
The new study, published in The European Journal of Internal Medicine, found cannabis therapy is safe and efficacious for elderly patients who are seeking to address cancer symptoms, Parkinson's disease, post-traumatic stress disorder, ulcerative colitis, Crohn's disease, multiple sclerosis, and other medical issues. After six months, more than 18 percent of patients surveyed had stopped using opioid analgesics or had reduced their dosage.
'Molly' is growing in popularity within the African-American community. New research shows much of that has to do with rap lyrics.
