Smoking May Counteract Benefit of Moderate Drinking on Stroke Risk

New research finds any beneficial effect of drinking moderate amounts of alcohol on stroke may be counteracted by cigarette smoking, according to research that will be presented as part of the late-breaking science program at the American Academy of Neurology’s 62nd Annual Meeting in Toronto, April 10 – 17, 2010.

Sleep Deprivation Influences Drug Use in Teens’ Social Networks

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.

Are Bees Also Addicted to Caffeine and Nicotine?

Bees prefer nectar with small amounts of nicotine and caffeine over nectar that does not comprise these substances at all, a study from the University of Haifa reveals. “This could be an evolutionary development intended, as in humans, to make the bee addicted,” states Prof. Ido Izhaki, one of the researchers who conducted the study.

Not Even a Puff: More Smokers Kick the Habit With Extended Nicotine Patch Therapy

New research from the University of Pennsylvania School of Medicine may help more smokers keep their New Year’s resolution by helping them quit smoking. 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.

Cocaine Exposure During Pregnancy Leads to Impulsivity in Male, Not Female, Monkeys

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.
