Nicotine sensitizes the mouse brain to the addictive effects of cocaine, according to recent NIDA-supported research. The results accord with the hypothesis that a person’s initial use of an addictive substance physiologically sensitizes his or her brain to the rewarding and addictive effects of other substances. If the findings carry over to people, then preventing youths from smoking might reduce their vulnerability to cocaine abuse and addiction, and cocaine-dependent individuals might ease their path to recovery by quitting smoking.
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.
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.
A modified therapeutic community program designed by NIDA-supported researchers helped Colorado offenders with co-occurring substance use and mental health disorders re-enter their communities and avoid recidivism after release from prison.
Towns that implemented a drug abuse prevention program called Communities That Care will see a return of $5.30 for each $1 they invested during the 5-year trial of the intervention, according to a cost-benefit analysis. The estimate is based on reductions in smoking and delinquency observed during the fourth year of the study among eighth-graders and the projected total costs of smoking, delinquency, and crime avoided over the lifetimes of study participants.
NIDA researchers have developed a computer program that motivates and encourages treatment-seeking when an individual is in a primary care physician’s waiting room. Users of the program, called Video Doctor, enter information on a portable device and receive feedback about health risks related to their drug abuse, along with advice, immediately prior to seeing their physician.
Dr. J. David Jentsch is the recipient of the 2011 Jacob P. Waletzky Memorial Award for Innovative Research in Drug Addiction and Alcoholism. Dr. Jentsch and colleagues at the University of California, Los Angeles, are studying genetic and neurochemical factors that influence individual differences in inhibitory control.
April 2012 A program involving home visits by nurses to low-income first-time mothers, starting during pregnancy and extending into the second year of their children’s lives, has a positive and long-lasting impact on families. Children who participated in the program were less likely than others to report having used alcohol, cigarettes, or marijuana at age 12.
Pregnant women who received financial incentives to refrain from smoking during late pregnancy were more successful at remaining abstinent and less likely to have babies with low birth weight, according to data from three trials.
