Randomized Controlled TrialVery-low-nicotine-content cigarettes and dependence among non-daily smokers.
The US Food and Drug Administration is considering reductions in the nicotine content of cigarettes to reduce smoking and tobacco dependence. A randomized study showed that even non-daily, intermittent smokers (ITS) reduced their cigarette consumption when switched to very-low-nicotine-content cigarettes (VLNCCs). This paper assesses whether switching ITS to VLNCCs results in decreased dependence and whether subsequent cigarette consumption is mediated by decreased dependence. ⋯ Among ITS, switching to VLNCCs results in reduced tobacco dependence. However, the reductions in dependence appear to be secondary to effects on cigarette consumption, and do not appear to be an independent predictor or cause of reduced cigarette consumption.

Identifying opioid prescribing patterns for high-volume prescribers via cluster analysis.
Despite recent decreases in opioid prescribing rates, evidence suggests there is substantial variation in the way opioids are prescribed by providers. This study aims to identify patterns in high-volume opioid prescribing. ⋯ These results provide a clearer picture of current patterns among high-volume prescribers, who accounted for almost two-thirds of all opioid prescriptions. In light of the ongoing opioid overdose epidemic, this knowledge is critical for prevention activities.

Randomized Controlled TrialIntegrated cognitive behavioral therapy for ADHD in adult substance use disorder patients: Results of a randomized clinical trial.
Attention Deficit Hyperactivity Disorder (ADHD) frequently co-occurs with Substance Use Disorders (SUDs). Standard ADHD pharmacotherapies are not effective in patients with this comorbidity and cognitive behavioral therapy (CBT) has not been tested in this population. This RCT aimed to compare the efficacy of Integrated CBT (CBT/Integrated) directed at adult ADHD and SUD with CBT directed at SUD only (CBT/SUD) in patients with SUD and ADHD (SUD + ADHD). ⋯ Compared to regular SUD cognitive behavioral therapy, integrated cognitive behavioral therapy resulted in a significant extra improvement in ADHD symptoms in SUD + ADHD patients.

Association between polygenic risk for tobacco or alcohol consumption and liability to licit and illicit substance use in young Australian adults.
Co-morbid substance use is very common. Despite a historical focus using genetic epidemiology to investigate comorbid substance use and misuse, few studies have examined substance-substance associations using polygenic risk score (PRS) methods. ⋯ To our knowledge, this is the first study to report significant genetic overlap between the polygenic risks for smoking initiation and alcohol consumption and the risk of initiating major classes of illicit substances. PRSs constructed from large discovery GWASs allows the detection of novel genetic associations.

Internalizing and externalizing factors on the pathway from adverse experiences in childhood to non-medical prescription opioid use in adulthood.
Research demonstrates strong associations between adverse childhood experiences (ACEs) and non-medical prescription opioid use (NMPO), but pathways are not understood, hindering prevention and treatment responses. ⋯ Internalizing and externalizing factors partially explained the pathway from ACEs to NMPO. Substance abuse may be more difficult to treat with co-occurring psychopathologies and maladaptive behaviors, highlighting the need to address trauma early in life.
