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.
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.
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.
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.
People with cannabis use disorder (CUD) are likely also to have social anxiety disorder (SAD), and comorbid SAD is associated with greater severity of cannabis-related problems. These findings highlight the importance of assessing CUD patients for SAD, as that disorder can be both a contributing cause and a consequence of CUD. Treating both disorders may be a key to helping patients recover from each.
Dr. Marilyn Huestis of NIDA’s Intramural Research Program talks about conducting research on drug effects with human subjects, developing tests to help law enforcement identify drugged drivers, and an assay to help identify children whose prenatal exposure to anti-HIV drugs may put them at risk for adverse developmental outcomes.
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.
Marijuana-dependent outpatients who were treated with the medication gabapentin in a pilot clinical trial reduced their cannabis use more and reported fewer symptoms of drug withdrawal than patients who received a placebo.
Fewer teens are using cigarettes, alcohol, and most illicit drugs, according to NIDA’s latest Monitoring the Future study. Troubling trends persist in marijuana use, however, and nonmedical prescription drug use remains a concern.
NIDA-funded researchers have gathered evidence that brief interventions can help adolescents move away from drug use. In a clinical trial, middle and high school students markedly reduced their substance use following two 60-minute sessions that combined motivational interviewing and cognitive behavioral therapy.
Illicit drug use in the United States in 2010 was at its highest level since 2002, according to the most recent report from the National Survey on Drug Use and Health. A rise in marijuana use drove the increase. A favorable trend of falling cocaine use continued.
Chronically delinquent boys in Multidimensional Treatment Foster Care reduced their substance abuse more than boys assigned to Community Group Care.
Reports on the relative influence of genes versus environment on adolescents’ choices that involve delayed gratification.
Describe a study of newly arrested youths where researchers found correlations between the youths' prevalence of these sexually transmitted diseases and their cocaine and marijuana use.
Reports 2010 rates of marijuana use among 8th, 10th, and 12th grade students, noting that daily use increased by more than 10 percent in all three grades since the 2009 survey. Also reports a rise in ecstasy use.
Reports on 2009 data indicating a rise in drug abuse in the United States and the factors that may have contributed to this increase.
