Correlates of use of electronic cigarettes versus nicotine replacement therapy for help with smoking cessation.
Electronic- or e-cigarettes are nicotine-delivery devices commonly used by smokers to quit or reduce smoking. At present, not much is known about the characteristics of smokers who specifically try e-cigarettes to quit smoking compared to the nicotine replacement therapy (NRT) products approved by the U.S. Food and Drug Administration (FDA). Determining the characteristics of smokers who are likely to choose e-cigarettes as cessation aids would help develop strategies to impart valid information about e-cigarettes to such smokers as facts regarding the safety and utility of e-cigarettes emerge. ⋯ Smokers who are attracted to use e-cigarettes but not FDA-approved NRT products may differ from smokers who are likely to have used NRT products but not e-cigarettes in terms of demographic (e.g., age, ethnicity) and smoking- or cessation-related characteristics (e.g., nicotine dependence, quit attempts). Given the lack of knowledge regarding the health effects of e-cigarettes and their efficacy as cessation aids, future research needs to continue characterizing smokers who are likely to use e-cigarettes for smoking cessation.

Psychometric properties of the Barratt Impulsiveness Scale in patients with gambling disorders, hypersexuality, and methamphetamine dependence.
Although the Barratt Impulsiveness Scale (BIS; Patton, Stanford, & Barratt, 1995) is a widely-used self-report measure of impulsivity, there have been numerous questions about the invariance of the factor structure across clinical populations (Haden & Shiva, 2008, 2009; Ireland & Archer, 2008). The goal of this article is to examine the factor structure of the BIS among a sample consisting of three populations exhibiting addictive behaviors and impulsivity: pathological gamblers, hypersexual patients, and individuals seeking treatment for methamphetamine dependence to determine if modification to the existing factors might improve the psychometric properties of the BIS. ⋯ The clinical utility of the BIS in this population is questionable. The authors suggest future studies to investigate comparisons with this modified version of the BIS and other impulsivity scales such as the UPPS-P Impulsive Behavior Scale in clinical populations when assessing disposition toward rash action.

Randomized Controlled TrialThe impact of pre-cessation varenicline on behavioral economic indices of smoking reinforcement.
Varenicline was developed to aid smoking cessation by reducing smoking reinforcement. The present study tests this reinforcement-reduction hypothesis among smokers preparing to quit. ⋯ Simulated smoking demand can be validly assessed in the natural environment of treatment-seeking smokers. Simulated demand indices of smoking reinforcement diminished as smokers approached their target quit date. However, there was no evidence that varenicline facilitated these changes over a three-week period, leaving open the mechanisms by which varenicline reduces smoking rate prior to cessation and improves long-term abstinence.

Sleep disturbances and pain among individuals with prescription opioid dependence.
Poor sleep quality has been observed in individuals with substance use disorders and is often a trigger for relapse. To date, little research has investigated sleep quality among individuals with prescription opioid (PO) dependence. The present study aimed to address this gap in the literature by examining subjective and objective sleep disturbances among PO dependent individuals. ⋯ Results indicate high rates of sleep impairment and poor sleep quality among PO dependent individuals. Pain severity was significantly correlated with sleep quality. Although preliminary, the findings highlight the importance of assessing and treating sleep disturbances, as well as pain, among patients with PO dependence.

Positive posttraumatic stress disorder screens among first-time medical cannabis patients: prevalence and association with other substance use.
Twenty-one states and the District of Columbia have passed legislation allowing for the use of medical cannabis for those individuals with qualifying medical conditions, which include posttraumatic stress disorder (PTSD) for a growing number of states. Little information is available regarding PTSD among medical cannabis patients. This study seeks to provide initial data on this topic by examining the prevalence and correlates of positive PTSD screens among a sample of patients seeking medical cannabis certification for the first time (n=186). ⋯ Moreover, the group that screened positive for PTSD had higher percentages of lifetime prescription opioid, cocaine, prescription sedative, and street opioid use, as well as a higher percentage of recent prescription sedative use, than the group that screened negative for PTSD. These findings highlight the relatively common use of other substances among medical cannabis patients with significant PTSD symptoms, even when compared with other patients seeking medical cannabis for the first time. As a growing number of states include PTSD among the list of qualifying medical conditions for medical cannabis, additional research is needed to better characterize the longitudinal relationship between medical cannabis use and PTSD symptoms.
