Study Pinpoints Cognitive Deficits Due to Cocaine, Finds Potential for Recovery

New research demonstrated that, in rhesus monkeys, ongoing cocaine exposure weakens two brain functions that people require for successful behavioral change: cognitive flexibility and memory. But the study determined that these changes may not be permanent.

Adolescent Cigarette, Alcohol Use Declines as Marijuana Use Rises

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.

Prenatal Methamphetamine Exposure Linked With Problems

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.

Animal Research Advances Effort to Develop Vaccines Against Cocaine, Heroin Abuse

New vaccines that aim to promote recovery from cocaine and heroin abuse showed promise in animal testing. Both vaccines induced rats’ immune system to produce high titers of antibodies that inhibit the target drug from reaching the brain. The rats’ behaviors when given access to the target drug indicated that the vaccines reduced the reinforcing effects that, in recovering people, can cause lapses to turn into relapses.

Physical Activity Reduces Return to Cocaine Seeking in Animal Tests

Two independent animal studies suggest that aerobic exercise might help cocaine abusers establish and maintain abstinence.

Stimulant Abusers' Regard for Future Improves With Memory Training

Researchers correlate stimulant abusers’ improved performance on a memory training exerc ise with reductions in delay discounting.

Marker for Neuronal Damage Resolves a Year after Methamphetamine

New results extend previous findings that some methamphetamine-induced neuronal damage resolves after a year of abstinence.

Disruption of Neuron Production in Adult Rats Increases Cocaine Taking

Drug abuse may diminish production of new neurons in the brain’s hippocampus and thereby increase vulnerability to drug addiction.
