NIDA Director Dr. Nora D. Volkow summarizes instances where discoveries with broad implications for human health arose from scientists seeking answers to addiction problems.

New studies show that microRNAs, snippets of RNA implicated in a wide variety of biological processes, are involved in promoting and inhibiting cocaine addiction. The findings could pave a new path for the development of anti-addiction therapies.

In a new series of studies tracing the molecular events that occur in the brain as memories are formed and preserved, researchers find that certain epigenetic changes may promote vulnerability to relapse.

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

An in vitro test demonstrates the potential of a programmable skin patch that will enable physicians to tailor transdermal medication doses to match patients' fluctuating needs.

Individuals with weak signaling in a nicotine-sensitive brain circuit were more vulnerable to nicotine dependence than those with stronger signaling, according to a study conducted while the subjects’ brains were in a resting state. A second resting-state study finds that the same circuit appears to mediate dependence associated with a genetic risk factor for smoking.
