Sleep Deprivation Influences Drug Use in Teens’ Social Networks

University of California San Diego Health

Recent studies have shown that behaviors such as happiness, obesity, smoking and altruism are “contagious” within adult social networks. In other words, your behavior not only influences your friends, but also their friends and so on. Researchers at the University of California, San Diego and Harvard University have taken this a step farther and found that the spread of one behavior in social networks influences the spread of another behavior, adolescent drug use.

Washington University in St. Louis

Exposure to severe stress early in life increases the risk of alcohol and drug addiction. Yet surprisingly, some adults sexually abused as children — and therefore at high risk for alcohol problems — carry gene variants that protect them from heavy drinking and its effects, according to researchers at Washington University School of Medicine in St. Louis.

Extended use of a nicotine patch – 24 weeks versus the standard eight weeks recommended by manufacturers – boosts the number of smokers who maintain their cigarette abstinence and helps more of those who backslide into the habit while wearing the patch, according to a study which will be published in the February 2 issue of Annals of Internal Medicine.

Adult male monkeys exposed to cocaine while in the womb have poor impulse control and may be more vulnerable to drug abuse than female monkeys, even a decade or more after the exposure, according to a new study by researchers at Wake Forest University School of Medicine. The findings could lead to a better understanding of human drug abuse.
