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

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 Northwestern U
Fewer than half of inmates in jails and prisons surveyed in a study by the CDC and University of Washington said they would accept a COVID-19 vaccine, while the majority either said they wanted to wait before getting the vaccine or would refuse one.

Between 2015 and 2017, Seattle, Washington, became the first U.S. city to increase its hourly minimum wage to $15, more than double the federal minimum wage and 60 percent higher than Seattle s previous minimum wage. A new study examined the impact of this change on public safety. The study was motivated by the idea that since crime is sometimes the result of material deprivation, changes in the minimum wage might have implications for criminal activity: Boosting the minimum wage could raise workers salaries (which could be associated with reduced crime). But if higher minimum wages spur employers to substitute capital for labor, this could increase unemployment (which could be associated with increased crime). The study found little evidence that Seattle s aggregate rate of violent or property crimes changed relative to other U.S. cities. It also found no meaningful adverse effects on low-wage workers rates of employment.

The U.S. criminal legal system has expanded at a rapid pace, even as crime rates have declined since the 1990s. As a result, individuals interactions with and surveillance by law enforcement are now commonplace. But citizens experience different interactions, with people of color who live in impoverished urban communities having the most frequent encounters. A new study interviewed young Philadelphia men to determine their perceptions of and reactions to this phenomenon. Nearly all of the men of color said they stayed at home and avoided public spaces out of concern over the potential interactions with others that might draw police attention.
