Definitive proof of an adverse effect of chronic marijuana use revealed at SNM’s 58th Annual Meeting could lead to potential drug treatments and aid other research involved in cannabinoid receptors, a neurotransmission system receiving a lot of attention.

Over the past decade, prominent federal substance abuse agencies have put a great deal of effort toward ensuring that evidence-based practice (EBP) is being utilized in the treatment of addiction. This effort was galvanized by a 1998 report from the Institute of Medicine calling for improvements in healthcare, which included the implementation of practices proven […]
Dozens of studies on whether moderate exercise can curb the nicotine cravings of women smokers have added up to an apparent contradiction: it seems to work in short-term, well controlled lab experiments, but then fizzles out in treatment trials. A new study may explain why and help researchers devise a practical therapy.
Researchers at Washington University School of Medicine in St. Louis and King’s College London have independently identified DNA on chromosome 3 that appears to be related to depression. Jim Dryden explains these results in an audio interview with the researchers; check the end of this report for a link to this interview.
Exposure to secondhand smoke, such as a person can get by riding in an enclosed car while someone else smokes, has a direct, measurable impact on the brain — and the effect is similar to what happens in the brain of the person doing the smoking. In fact, exposure to this secondhand smoke evokes cravings […]
According to the study, 50% of patients suffering from bipolar disorder suffers some type of work, social, and family disability, and approximately 20% present some disorder at the three levels. This was the conclusion drawn in a cientific article recently published in the prestigious journal Psychiatry Research, prepared by Dr. Luis Gutiérrez Rojas, a member […]
Two reports by addiction researchers at the University of Pennsylvania School of Medicine and the National Institute on Drug Abuse show a drastic shift in prescribing patterns impacting the magnitude of opioid substance abuse in America. The reports, published in JAMA, recommend a comprehensive effort to reduce public health risks while improving patient care, including better […]
Persons with an addictive-like eating behavior appear to have greater neural activity in certain regions of the brain similar to substance dependence, including elevated activation in reward circuitry in response to food cues, according to a report posted online today that will appear in the August print issue of Archives of General Psychiatry, one of the […]
