Substance use linked to company we keep

The saying “You are who you hang around with” seems especially true when it comes to alcohol, cigarette and drug use. Researchers at Washington University School of Medicine in St. Louis are reporting that people who hang out with marijuana, cigarette or alcohol users are not only more likely to do the same, but that exposure allows genetic tendencies for substance use to become more robust.  

Misleading advertising

Robert K. Jackler, MD, spoke at the School of Medicine March 9 about his exhibit that shows how the advertising industry used medical science to promote cigarette smoking in the 20th century.

Tobacco advertising: Science … or smokescreen?

Robert K. Jackler, M.D., the Sewall Professor and Chair of otolaryngology and associate dean at Stanford University School of Medicine, has gathered advertisements using doctors to promote cigarettes into an exhibit that will be on display in the Farrell Learning and Teaching Center and the Bernard Becker Medical Library beginning Monday, March 1 through Friday, April 30. He also will give a free, public lecture at noon Tuesday, March 9, in Connor Auditorium.

Addiction study to examine interaction of genes and environment

A psychiatric geneticist at the School of Medicine is one of several principal investigators around the country who will participate in the Genes, Environment and Health Initiative (GEI), a unique collaboration between geneticists and environmental scientists. The $48 million initiative is sponsored by the National Institutes of Health (NIH). Laura Jean Bierut, M.D., professor of psychiatry at the School of Medicine, will head the national study of addiction, looking both at genetic and environmental factors that contribute to the problem.

Cigarette smoking impairs ligament healing, researchers find

The list of reasons you shouldn’t smoke has gotten longer. Researchers at the School of Medicine are reporting that smoking interferes with ligament healing. Each year in the United States there are more than 20 million reported ligament injuries, and MCL injuries — which affect a ligament supporting the knee joint — are the most common. Studying mice with MCL injuries, the team discovered cigarette smoking impairs the recruitment of cells to the injury site and delays healing following ligament repair surgery.

Prenatal smoking increases ADHD risk in some children

Smoking while pregnant combined with genetic factors greatly increases the risk of severe ADHD.Past research has suggested that both genes and prenatal insults — such as exposure to alcohol and nicotine — can increase the risk of attention-deficit/hyperactivity disorder (ADHD). But the identified increases in risk have been very modest. Now, a team of Washington University scientists has found that when those factors are studied together, risk of a severe type of ADHD greatly increases.

Studies identify DNA regions linked to nicotine dependence

Americans are bombarded with antismoking messages, yet at least 65 million of us continue to light up. Genetic factors play an important role in this continuing addiction to cigarettes, suggest scientists at the School of Medicine. They show that certain genetic variations can influence smoking behaviors and contribute to a person’s risk for nicotine dependence.
