At least some recreational users of illegal drugs may choose not to take them if tests show the pills are adulterated or fake, shows data collected over five years by volunteers who tested pills free of charge at music festivals and raves across the United States. The results also revealed that pills/powder sold as “Molly” – believed by users to be a purer and safer version of the illegal stimulant drug MDMA – contained as many harmful additives as the version known as Ecstasy.

Experts have issued numerous statements about the dangers of alcohol consumption during pregnancy, as it can lead to Fetal Alcohol Spectrum Disorders (FASD). Now a new study finds that prenatal ethanol exposure (from maternal alcohol consumption during pregnancy) causes abnormalities in the brain and behavior that may be passed on for many generations.

Benefits of middle school prevention program extend into emerging adulthood, according to long-term study
Children who participated in the PROSPER (PROmoting School-community-university Partnerships to Enhance Resilience) program over seven years ago showed lower rates of substance abuse after high school graduation, according to a new study.

Exposure to alcohol before birth may make drinking more appealing to teens
Fetal alcohol exposure (FAE) reduces the taste system’s responsiveness to the bitter flavor and burning sensation of many varieties of alcoholic beverages, new research shows. These factors make alcohol unappealing to some people, but, for reasons that are unclear, are less of a deterrent in young people exposed to alcohol before birth. Read more
Binge drinking accelerates alcohol use disorder, but stable daily drinking may be just as risky in the long-term
Binge drinking may increase people’s risk of developing alcohol use disorders (AUDs), especially adolescents and young adults, research shows. It is unclear whether different drinking patterns – for example, intermittent versus regular drinking – have a different impact on the compulsive drinking that characterizes people with AUDs. This study used rats to examine whether chronic intermittent alcohol access facilitates a transition to compulsive-like drinking. Read more

Drinking during adolescence can alter brain cell nerve growth
The developmental period from adolescence to adulthood is accompanied by a greater vulnerability to addictions than is seen in other periods of life. A new report describes a study in mice of the neurobehavioral impact of chronic, intermittent alcohol-vapor exposure during adolescence, in an effort to model periodic heavy drinking and compare it with similar drinking behavior during adulthood.
