Background—Cannabis use disorder (CUD) is a prevalent and impairing condition, and established psychosocial treatments convey limited efficacy. In light of recent findings supporting the efficacy of N-acetylcysteine (NAC) for CUD in adolescents, the objective of this trial was to evaluate its efficacy in adults.

Methods—In a 12-week double-blind randomized placebo-controlled trial, treatment-seeking adults ages 18–50 with CUD (N=302), enrolled across six National Drug Abuse Treatment Clinical Trials Network-affiliated clinical sites, were randomized in a 1:1 ratio to a 12-week course of NAC 1200 mg (n=153) or placebo (n=149) twice daily. All …

Neurophysiological Capacity In A Working Memory Task Differentiates Dependent From Nondependent Heavy Drinkers And Controls, Michael J. Wesley, Joshua A. Lile, Mark T. Fillmore, Linda J. Porrino

Behavioral Science Faculty Publications

Background—Determining the brain-behavior profiles that differentiate heavy drinkers who are and are not alcohol dependent will inform treatment efforts. Working memory is linked to substance use disorders and can serve as a representation of the demand placed on the neurophysiology associated with cognitive control.

Methods—Behavior and brain activity (via fMRI) were recorded during an N-Back working memory task in controls (CTRL), nondependent heavy drinkers (A-ND) and dependent heavy drinkers (A-D). Typical and novel step-wise analyses examined profiles of working memory load and increasing task demand, respectively.

Results—Performance was significantly decreased in A-D during high working memory load …

Running Away From Addiction: Can Exercise Attenuate Methamphetamine-Induced Neurotoxicity?, Ashley N. Fricks-Gleason

Celebration of Scholarship and Research

Methamphetamine (METH) abuse continues to be a major public health concern. Use is endemic in the Western states and growing in the Midwest; Colorado currently ranks 7th in the nation for total number of METH users over the age of 25. Psychostimulant abuse carries with it several potential health risks, including addiction, and METH abuse carries the additional danger of permanent brain injury. It is well established that exposure to multiple high doses of METH produces damage to central monoamine systems. Long-lasting decreases in markers of dopamine (DA) innervation of the striatum have been reported in both human METH abusers …

The Use And Abuse Of Mutual-Support Programs In Drug Courts, Sara Gordon

Scholarly Works

There is a large gap between what we know about the disease of addiction and its appropriate treatment, and the treatment received by individuals who are ordered into treatment as a condition of participation in drug court. Most medical professionals are not appropriately trained about addiction and most addiction treatment providers do not have the education and training necessary to provide appropriate evidence-based services to individuals who are referred by drug courts for addiction treatment. This disconnect between our understanding of addiction and available addiction treatment has wide-reaching impact for individuals who attempt to receive medical care for addiction in …

Attitudes About Future Genetic Testing For Posttraumatic Stress Disorder And Addiction Among Community-Based Veterans., Michelle R. Lent, Stuart N Hoffman, H Lester Kirchner, Thomas G Urosevich, Joseph J Boscarino, Joseph A Boscarino

PCOM Scholarly Papers

This study explored attitudes toward hypothetical genetic testing for posttraumatic stress disorder (PTSD) and addiction among veterans. We surveyed a random sample of community-based veterans (n = 700) by telephone. One year later, we asked the veterans to provide a DNA sample for analysis and 41.9% of them returned the DNA samples. Overall, most veterans were not interested in genetic testing neither for PTSD (61.7%) nor for addiction (68.7%). However, bivariate analyses suggested there was an association between having the condition of interest and the likelihood of genetic testing on a 5-point scale (p < 0.001 for PTSD; p = 0.001 for …
