A study looking at the cumulative effects of depression in youth, found that young people with chronic or severe forms of depression were at elevated risk for developing a problem with cannabis in later adolescence.
The study led by UW Medicine researchers interviewed 521 students recruited from four Seattle public middle schools. Researchers used data from annual assessments when students were ages 12-15 and then again when they were 18. The results were published in the journal Addiction.
“The findings suggest that if we can prevent or reduce chronic depression during early adolescence, we may reduce the prevalence of cannabis use disorder,” said lead author Isaac Rhew, research assistant professor of psychiatry and behavioral sciences at the University of Washington School of Medicine.

People with anxiety and depression have a high rate of prescription opioid use, a new study finds.
Almost 19 percent of the estimated 38.6 million people diagnosed with anxiety and depression received at least two prescriptions for opioids in one year, the study found. More than half of opioid prescriptions went to people with these mental health disorders, according to The Washington Post.
People with anxiety and depression may feel pain more acutely, or may be less able to cope with the pain, leading to increased requests for opioids, said lead researcher Brian Sites of Dartmouth’s Geisel School of Medicine.

Teenagers injured through drinking, drug abuse or self-harming have a five-fold increased risk of dying from suicide in the next decade.
Children and young people admitted to hospital in England with injuries related to self-harming, drugs or alcohol faced an increased risk of killing themselves over the following 10 years, according to new research.
While previous studies have shown that children and adolescents who self-harm are at a higher risk of suicide, the paper by academics from UCL and the University of Leeds, argues that the risks apply to a larger group of adolescents.
A new study led by the University of Delaware found that kids who are bullied in fifth grade often suffer from depression and begin using alcohol and other substances a few years after the incidents.
“Students who experienced more frequent peer victimization in fifth grade were more likely to have greater symptoms of depression in seventh grade, and a greater likelihood of using alcohol, marijuana or tobacco in tenth grade,” said the study’s leader, Valerie Earnshaw, a social psychologist and assistant professor in UD’s College of Education and Human Development.
The study involved researchers from universities and hospitals in six states, who analyzed data collected between 2004 and 2011 from 4,297 students on their journey from fifth through tenth grade. The findings were published online in the medical journal Pediatrics.

The prevalence of smoking has remained fairly stable over the past decade after declining sharply for many years. To determine whether an increase in certain barriers to successful cessation and sustained abstinence may be contributing to this slowed decline, researchers at Columbia University’s Mailman School of Public Health analyzed changes in the prevalence of depression among current, former and never smokers in the U.S. The team found that depression appeared to have significantly increased in the U.S. from 2005 to 2013 among smokers, as well as among former and never smokers. While the prevalence of depression is consistently highest among smokers, the rate of increase in depression was most prominent among former and never smokers. The full study findings are published online in the journal Drug and Alcohol Dependence.
The research team, led by Renee Goodwin, PhD, in the Department of Epidemiology, analyzed data from the National Household Survey on Drug Use, an annual cross-sectional study of approximately 497, 000 Americans, ages 12 and over. The prevalence of past 12-month depression was examined annually among current (past 12-month), former (not past 12-month), and lifetime non-smokers from 2005 to 2013. The researchers further analyzed the data by age, gender, and household income.
