Mechanism links substance abuse with vulnerability to depression

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.

Research suggests symptoms of food addiction similar to drug addiction

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.

Research examines dentists’ role in painkiller abuse

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.

Smoking initiation at a young age tied to greater risk of illicit drug use

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.

Early male friendship as a precursor to substance abuse in girls

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.

Exercise can curb marijuana use and cravings

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.

Genetic makeup and duration of abuse reduce the brain’s neurons in drug addiction

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.

Six out of ten male drug-addicts abuse their partners

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.
