Regular cannabis use that starts in adolescence strips away IQ, a NIDA-supported study suggests. Participants who initiated weekly cannabis use before age 18 dropped IQ points in proportion to how long they persisted in using the drug. Persistent cannabis users’ cognitive difficulties were evident to friends and family and measurable on a battery of tests.

When the goal is to avoid using alcohol and illicit substances after being released from jail, it’s who one’s friends are that counts most. Self-control is important because it helps a person have the right kind of friends.

Patients were more likely to take a rapid HIV test when substance abuse treatment programs offered the test onsite rather than referred for offsite testing. Patients were equally likely to accept and learn their HIV status whether the offer of onsite testing was accompanied by 30 minutes of risk reduction counseling or by 5 minutes of brief information on the testing procedure. Onsite testing accompanied by brief information was cost effective, taking into account the projected lifetime costs of treatment and the gains in health and longevity for detected cases.

People who use prescription opiates nonmedically are more likely to consider suicide than those who use these medications only appropriately or not at all. A recent NIDA-supported study also disclosed that the risk for suicidal thoughts remains elevated after cessation of use.

Teens who participated in the intervention Strong African American Families‒Teen at age 16 reported fewer conduct problems and depressive symptoms and less substance abuse at age 17‒18, compared to peers exposed to a control intervention.

Study findings indicate that children exposed to methamphetamine prenatally show more signs of increased emotionality, anxiety, and depression than nonexposed children at ages 3 and 5 years.

The NIDA-supported Good Behavior Game recently was honored with the 2012 Mentor International Best Practice Award. The game, which focuses on reducing disruptive behaviors in elementary school classrooms, has been shown to prevent drug abuse and other problems in adolescence and young adulthood.
