July 2014 Interventions that bolster self-control in childhood and early adolescence might shield ethnic and racial minority adolescents and young adults from the burden of both drug use and depressive mood.
Within the 2 weeks prior to responding to a nationwide survey, 28 percent of high school seniors were in a vehicle whose driver had been using marijuana or another illicit drug, or had drunk 5 or more alcoholic drinks.
Driving under the influence of marijuana is a dangerous public health concern. NIDA researchers have discovered that breath expelled into a Breathalyzer-style collection device contained measurable amounts of THC for up to 2 hours after participants in a recent clinical trial smoked the drug.
April 2014 Exposing rats to THC increases the likelihood that the animals will later self-administer nicotine. THC-exposed rats are also willing to work harder to obtain nicotine. When extrapolated to people, the findings suggest that THC’s pharmacological impact on the brain may make a person who uses marijuana more vulnerable to developing nicotine addiction, an underappreciated health consequence of marijuana use.
April 2014 Almost one-third (32 percent) of the roughly 42,000 Monitoring the Future survey respondents reported having used marijuana during their lifetime. However, abuse of many other drugs—methamphetamine, heroin, cocaine, and some prescription medications—declined.
February 2014 Teen mothers on three American Indian reservations improved on several measures of parenting after participating in Family Spirit, a home-visiting intervention developed with NIDA support. At 12 months postpartum, the women’s children exhibited reduced rates of emotional difficulties predicting later drug abuse and other behavioral problems. Infants at highest risk—those whose mothers had histories of drug abuse—benefited the most.
