Imaging Study Shows Awareness Deficit in Marijuana Abusers
|
|
A new study funded by NIDA has used brain-imaging technology to show that during a decision game, chronic marijuana users show less activity in an error-processing part of their brains than peers who do not use marijuana. These results provide preliminary evidence in the debate on whether substance abusers willfully ignore their problem or whether cognitive deficits prevent them from fully understanding their addiction and its potential consequences.

CREB Protein Activity in the Nucleus Accumbens Shell Mediates Environmental Cues Associated with Nicotine
|
|
To understand whether the molecule CREB is required for environmental associations with smoking, researchers funded by NIDA performed a series of conditioned place preference (CPP) experiments using mice. CPP occurs when an animal is exposed to a pleasurable drug in a specific environment, and learns to prefer that environment over others when given a choice. The researchers exposed mice to either nicotine or a control injection for three days and immediately placed the mice in one of two visually distinct environments, to allow a CPP to develop. Mice that received nicotine injections and developed a CPP showed increased CREB activity in the NAc shell when placed their preferred environment, even without exposure to nicotine. Mice who had received the control injections did not show an increase in CREB activity in the same test.

'Dramatic' rise in adult substance abuse
|
|
According to a report from the federal Substance Abuse and Mental Health Services Administration, a recent survey shows a "dramatic" increase in the number of older adults using illicit drugs, which "may require the doubling of substance abuse treatment services" for this population by 2020. And that survey didn't even include the legal drug — alcohol — which is the major substance-abuse problem for those 60 and older.

Alcohol, Gender, Culture and Harms in the Americas
|
|
This is the final report of a multi-centric study carried out by the Pan American Health Organization (PAHO). The report covers studies in
Argentina, Belize, Brazil, Canada, Costa Rica, Mexico, Nicaragua, Peru, Uruguay and the United States. "This new survey data highlight the importance of disaggregating sub-regional WHO data to the country level in order to see differences in consumption and corresponding risk of alcohol–attributable outcomes at the country level and thus inform country-specific alcohol policies capable of addressing the specific alcohol consumption profiles and problems." | |
