Intensified screening for HIV among injection drug users receiving opioid agonist therapy could prevent more than twice as many new infections as current screening practice. A recent study based on mathematical modeling found that screening every 6 months instead of annually, and adding viral RNA testing to the currently used HIV antibody testing, could improve both effectiveness and cost-effectiveness.
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.
Women who reached their majority in states with policies that restricted teens’ access to tobacco products were less likely to smoke from ages 18-34 than women in states without those policies. The research did not demonstrate that the policies had a comparable impact on men’s smoking.
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.
