Forty-seven percent of substance abuse treatment counselors in a national sample left their jobs voluntarily within 3 years.

Clinical trials of N-acetylcysteine to help people recovering from drug abuse avoid relapse have demonstrated only moderate efficacy. New NIDA-supported research shows that while a low dose of the medication activates receptors associated with lowered drug-seeking behavior, a higher dose appears to activate receptors associated with increased drug-seeking behavior. The result suggests that a medication or combination of medications that stimulate the receptor GluR2/3 and block mGluR5 may work better than N-acetylcysteine alone.

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.

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.

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.
