The latest news about addiction and substance abuse research
People who frequently use tanning beds may be spurred by an addictive neurological reward-and-reinforcement trigger, researchers at UT Southwestern Medical Center have found in a pilot study.
Research to be presented at the upcoming annual meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that people can become dependent on highly palatable foods and engage in a compulsive pattern of consumption, similar to the behaviors we observe in drug addicts and those with alcoholism.
The Obama administration turned a bright spotlight on prescription painkiller abuse in April when the Office of National Drug Control Policy released a national action plan and a statement from Vice President Joe Biden. With a cover article in the July edition of the Journal of the American Dental Association (JADA), dentists focus that spotlight on themselves both as major sources of opioid drugs and as professionals with largely untapped power to recognize and reduce abuse.
Marijuana is the most prevalent illicit drug used by teenagers and adults around the world. Nearly a third of high school students in the United States report smoking it, and most high schoolers say they have access to the drug.
Clinically ascertained reports suggest that boys and girls with attention deficit hyperactivity disorder (ADHD) may differ from each other in their vulnerability to substance use problems, say the researchers of the University of Helsinki and University of Jyväskylä, Finland.
Patients in residential treatment programs for drug and alcohol abuse may benefit from cognitive behavioral therapy for depressive symptoms, according to a report in the June issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Illicit drug overdose deaths declined dramatically after the establishment of North America’s first supervised injection facility located in Vancouver, Canada, according to the findings of a groundbreaking new study published in The Lancet.
A new study published in The American Journal on Addictions reveals that Veterans who suffer from mental health disorders also have high rates of substance use disorders.
Two papers recently published in Biological Psychiatry now suggest that drugs that stimulate two different subclasses of PPARs may play roles in the treatment of nicotine and alcohol addiction by acting in the brain.
Young people who start smoking at an early age have a much higher risk of starting to use cannabis by the time they turn 17. Risk factors that increase the likelihood of starting to smoke include externalising problem behaviours such as impulsiveness. Smoking, in turn, is a significant risk factor for cannabis use. These results have been confirmed in a project researching smoking at an early age and externalising behaviour as predictors of drug use. The project has been funded by the Academy of Finland’s Research Programme on Substance Use and Addictions.
A new study published in Journal of Research on Adolescence suggests that girls and boys experience this transition very differently. The findings show that girls tend to initiate the transition to a mixed-gender friendship network earlier than boys, and continue this transition at a faster pace during adolescence. As a result girls who experienced this transition early and fast were more likely to develop substance abuse problems during late adolescence.
Vanderbilt researchers are studying heavy users of marijuana to help understand what exercise does for the brain, contributing to a field of research that uses exercise as a modality for prevention and treatment.
A study conducted at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory demonstrated that drug addicted individuals who have a certain genetic makeup have lower gray matter density – and therefore fewer neurons – in areas of the brain that are essential for decision-making, self-control, and learning and memory.
According to a study conducted at the Department of Pedagogy of the University of Granada, about six out of ten male drug-abusers direct some type of violence against their intimate partners. Thus, the study revealed a high rate of domestic violence –both pysical and psychological– by male drug-abusers against women. The study also detailed the most recurrent forms of abuse, as well as the variables associated to them.
A brain imaging study at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory reveals a subtle difference between ordinary obese subjects and those who compulsively overeat, or binge: In binge eaters but not ordinary obese subjects, the mere sight or smell of favorite foods triggers a spike in dopamine — a brain chemical linked to reward and motivation. The findings — published online on February 24, 2011, in the journal Obesity — suggest that this dopamine spike may play a role in triggering compulsive overeating.
