Cigarette smokers are more likely to commit suicide than people who don’t smoke, a relationship that has been attributed to the fact that numerous people with psychiatric disorders, who have higher suicide rates, also tend to smoke. But a new study by researchers at Washington University School of Medicine in St. Louis finds that smoking itself may increase suicide risk and that policies to limit smoking reduce suicide rates.

Hundreds of thousands of American youth are following marijuana-related Twitter accounts and getting pro-pot messages several times each day, according to researchers at the School of Medicine. They said the tweets are cause for concern because young people are thought to be especially responsive to social media influences and because patterns of drug use tend to be established in a person’s late teens and early 20s.

Studying children with autism and their parents, researchers have found that when a child has autism, his or her parents are more likely to have autistic traits than parents who don’t have a child with an autism spectrum disorder, as measured by a survey used to identify such characteristics. Pictured is one of the study’s authors, John Constantino, MD.

A nationwide survey of heroin users indicates they are attracted to the drug not only for the “high” but because it is less expensive and easier to get than prescription painkillers. Shown is the study’s principal investigator, Theodore J. Cicero, PhD, of the School of Medicine.

Young adults with autistic tendencies don’t often engage in social or binge drinking, but if they drink, they are slightly more likely than their peers to develop alcohol problems, according to new research from Duneesha De Alwis (right) and Arpana Agrawal at the School of Medicine.

Although tobacco companies are barred by law from advertising their products to children, researchers at Washington University School of Medicine have found that many teens and pre-teens are getting tobacco advertisements and promotions through social media outlets or text messaging on mobile phones. More than one in 10 children under 18 reported receiving tobacco coupons or promotions on their Facebook or MySpace pages or in text messages.

A panel of experts, including researchers from the School of Medicine, is recommending that depression be added to obesity, diabetes, high blood pressure and smoking as a cardiac risk factor.​

Although many health professionals who treat people with psychiatric problems overlook their patients’ smoking habits, new research at the School of Medicine shows that people who struggle with mood problems or addiction can safely quit smoking and that kicking the habit is associated with improved mental health.

Laura Jean Bierut, MD, has been named the Alumni Endowed Professor of Psychiatry at the School of Medicine. Her work focuses on the genetic and environmental influences that contribute to addiction and other psychiatric disorders.

In a surprising discovery, neuroscientists, led by a team from Washington University School of Medicine in St. Louis, have found that a molecule that is a breakdown product of cholesterol in the brain may be a target for developing new drugs to treat schizophrenia and other mental illnesses.
