Why is it so difficult to stop smoking? Why do some people relapse months after giving up? Scientists from the Institut Pasteur and the CNRS, in collaboration with Sorbonne University and Inserm, have demonstrated that a genetic mutation already known to be involved in sensitivity to nicotine also plays a role in relapse behavior after cessation in rats. The findings will be published in the journal Current Biology on Oct. 4, 2018.
A 1 percent increase in statewide depression diagnoses was associated with a 26 percent increase in opioid-related deaths.

Adolescents who use vaping products are not only more likely to smoke cigarettes but are also likely to increase their use of both products over time, according to a new study.
In a study examining the potential impact of 2001-02 Medicaid expansions by Arizona, Maine and New York -- expansions that occurred just prior to the rise in overdose mortality nationwide -- researchers from the Perelman School of Medicine at the University of Pennsylvania found that from the time of these expansions through 2008, overdose mortality rates (mostly driven by fatal overdoses of opioids) rose significantly less in the expansion states than in non-expansion states.
Most teens who've tried marijuana used it in more than one form, raising concerns about adolescent health amid a booming cannabis market.
Opioid-related deaths contributed to more than 60 000 U.S. lives lost in 2016 but absolute declines in life expectancy relative to other countries and in various measures of psychosocial well-being have been observed starting as early as 1980. Researchers provide an overview of trends toward both increasing despair and declining health observed among many groups of people in the United States.
A review article published in the New England Journal of Medicine discusses the effects of alcohol use on various forms of liver disease, as well as the assessment and treatment of alcohol use in patients with chronic liver disease.
