Simultaneous Use of Alcohol and Marijuana: Patterns and Individual Differences.
Conclusions/Importance: It is clear that SAM users are a vulnerable sub-population of young adult drinkers. SAM users are differentiated from alcohol-only users in terms of their personality characteristics and perceptions of peer groups' drinking. SAM users and more frequent users are also at heightened risk for substance use outcomes. Prevention and intervention efforts targeting high-risk drinking may benefit from also assessing whether they simultaneously use alcohol and marijuana.

Risk-Taking Propensity, Affect, and Alcohol Craving in Adolescents' Daily Lives.
Conclusions/Importance: Momentary fluctuations in positive affect predicted acute increases in craving but only in moments when adolescents demonstrated higher levels of risk-taking propensity, as captured with an EMA-delivered behavioral task. Momentary risk-taking assessments offer new avenues to substantiate dominant theories on the driving mechanisms of craving and alcohol use among adolescents.

The Effects of Marijuana Use on Transitions through Stages of Alcohol Involvement for Men and Women in the NESARC I and II.
Authors: Green KM, Reboussin BA, Pacek LR, Storr CL, Mojtabai R, Cullen BA, Crum RM Abstract Background: With the changing context of marijuana use, it is critical to identify effects of use. We extend previous work by examining whether marijuana use influences progression and remission through alcohol involvement stages for men and women. Methods: Data come from Waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, n = 34,432). We assess the potential influence of marijuana use at Wave 1 on transitions across three latent statuses of alcohol involvement betwee...

Attenuation of response to drug-related cues in male heroin abstainers is modulated by cognitive control mechanisms.
Conclusions/Importance: Among abstinent heroin users, attentional bias to drug-related cues was moderated by attentional control. Further, high cognitive control demand was found to reduce heroin users' ability to resist attentional capture from salient, but irrelevant, drug-related information, which may contribute to compulsive drug-seeking behavior and relapse in heroin users.

Cue Exposure Therapy for Alcohol Use Disorders: What Can Be Learned from Exposure Therapy for Anxiety Disorders?
Conclusions: There are theoretical and practical similarities between exposure to fear cues and cues of addiction, especially regarding extinction learning. However, these processes are also unique, particularly regarding the differing motivational properties of fear versus reward-related stimuli. We propose that unlike exposure for anxiety, CET takes effect by increasing self-control with each unreinforced exposure. We consider reasons for CET's limited use for AUDs, including its lower acceptability to clients and clinicians. We also note the limited evidence for CET for other substance use disorders, highlighting the ne...

Chemical Markers for Short- and Long-Term Areca Nut Exposure.
Conclusions/Importance: LC-UV/VIS analysis of the red pigments extracted from saliva and BCs after AN chewing showed distinct signals up to 24 h post chewing while DART-MSMS analysis in BCs and scalp hair showed selective signals of AN alkaloids for several weeks or months after AN exposure. Chemical hair treatment might prevent detection of areca alkaloids in hair. AN cessation trials and other programs now have essential tools for bioverification.
