Helping smokers deal with financial problems could improve their chances of staying abstinent after receiving treatment, according to a new study. Participants with the most financial strain had the least success in remaining abstinent.
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.
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.
Presents current knowledge on a variety of addiction issues, including nicotine’s affects on brain function; inhalant abuse; genetically-based research and treatment; maternal tobacco use and its effects on children; and a behavior game for young children.
