The latest news about addiction and substance abuse research
Delaying the age when kids try alcohol or smoking decreases the likelihood that they will become dependent later in life. Effective interventions exist, but community disagreements about which programs to try can stymie decisions.
Scientists are reporting development of three promising formulations that could be used in a vaccine to treat methamphetamine addiction — one of the most serious drug abuse problems in the United States.
The Uppsala researchers and their colleagues have recently shown that dopamine cells in the reward system can send signals in cooperation with glutamate, so called co-signaling. Its physiological role was not previously known, however. For instance, how important is it for the inclination to ingest reward substances?
It is well established that a mood disorder can increase an individual’s risk for substance abuse, but there is also evidence that the converse is true; substance abuse can increase a person’s vulnerability to stress-related illnesses. Now, a new study finds that repeated cocaine use increases the severity of depressive-like responses in a mouse model of depression and identifies a mechanism that underlies this cocaine-induced vulnerability.
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.
