Scientists put the stopwatch on cannabis intoxication


Credit: NSW Government
A comprehensive analysis of 80 scientific studies has identified a window of impairment of between three and 10 hours caused by moderate to high doses of the intoxicating component of cannabis, tetrahydrocannabinol (THC). The findings have implications for the application of drug-driving laws globally, researchers say.
The study found the exact duration of impairment depends on the dose of THC, whether the THC is inhaled or taken orally, whether the cannabis user is regular or occasional and the demands of the task being undertaken while intoxicated.
The study represents the first such meta-analysis and distilled the results of 80 separate scientific studies into THC-induced impairment conducted over the past 20 years. It has been published in ....

Convenience over reputation: Study looks at how older adults pick a doctor


Credit: University of Michigan
Convenience and access win out over reputation when people over 50 look for a doctor for themselves, a new study finds.
But online ratings and reviews of physicians play an important role, and should receive attention from providers and policymakers, the researchers say.
About 20% of older adults called such ratings very important to them, but 43% said they had checked such reviews in the past for physicians they were considering for themselves.
Still, factors like insurance acceptance, appointment availability, location and hours won out over reputational information, although about 40% said a recommendation from another physician was very important to them. Recommendations from family and friends were rated as very important by about 20% of older adults. ....

Study finds psychiatric disorders persist 15 years after youth are detained


 E-Mail
CHICAGO - A new study shows that youth arrested as juveniles with psychiatric disorders that remain untreated, struggle with mental health and successful outcomes well beyond adolescence.
Research from Northwestern Medicine shows nearly two-thirds of males and more than one-third of females with one or more existing psychiatric disorders when they entered detention, still had a disorder 15 years later.
The findings are significant because mental health struggles add to the existing racial, ethnic and economic disparities as well as academic challenges from missed school, making a successful transition to adulthood harder to attain.
Kids get into trouble during adolescence.Those from wealthier families also use drugs and get into fights. But these situations are most often handled informally by the school and parent, and don t culminate in arrest and detention, said lead author Linda Teplin, Owen L. Coon Professor of psychiatry and behavioral sciences at ....

Weight loss changes people's responsiveness to food marketing: study


 E-Mail
Obesity rates have increased dramatically in developed countries over the past 40 years and many people have assumed that food marketing is at least in part to blame. But are people with obesity really more susceptible to food marketing? And if they are, is that a permanent predisposition, or can it change over time?
According to a new study by UBC Sauder School of Business Assistant Professor Dr. Yann Cornil (he/him/his) and French researchers, people with obesity do tend to be more responsive to food marketing but when their weight drops significantly, so does their responsiveness to marketing. ....
