Marijuana's Impact on Alcohol Motivation and Consumption
Alcohol DrinkingMarijuanaThis laboratory study will employ a repeated measures experimental design to examine the effect of high (7.2% THC) and moderate (3% THC) dose of marijuana, relative to placebo, on alcohol craving and on behavioral economic measure of alcohol demand after exposure to alcohol cues, and on subsequent drinking in an alcohol choice task in which participants choose either to drink or receive monetary reinforcement for drinks not consume. The study will recruit 173 non-treatment seeking heavy episodic alcohol drinkers who smoke marijuana at least twice weekly.

Effect of Moderate Alcohol Consumption to Cognitive Functioning After Roux-en Y Gastric Bypass
Bariatric SurgeryAlcohol Consumption1 moreObjectives: Alcohol metabolism is changed in gastric bypass patients, leading to faster resorption and higher alcohol peak concentrations in blood. Because of stronger alcohol effects after gastric bypass we suggest that also general cognitive function is stronger impaired. Materials and Methods: We included 28 females (12 gastric bypass patients, 8 obese and 8 normal weight subjects) in the study. Each participant had to drink 250 ml white wine. Directly before, 10-30 min after and 45-65 min after wine consumption cognitive functions were tested by test battery for attentional performance (TAP) from Zimmermann and Fimm. During the whole examination breath-alcohol-contents (BACs) were measured every 5 minutes with breathalyser "Dräger Alcotest 7510".

A Clinical Trial of SBIRT Services in School-based Health Centers
Marijuana UseAlcohol Consumption2 moreThe purpose of the study is to examine the comparative effectiveness of a computerized brief intervention vs. an in-person brief intervention delivered by a nurse in reducing marijuana, alcohol, and sex risk behaviors in adolescents receiving services in school-based health centers.

Mifepristone for the Prevention of Relapses of Alcohol Drinking
Alcohol Use Disorders (AUD)The goal of this study is to determine if, under stress, alcohol drinking is reduced using mifepristone

Behavior Brain Responses
Alcohol DrinkingDrinking Behavior2 moreTo compare responses to acute oral doses of ethanol in healthy young adults who experience mainly stimulant subjective effects from the drug or mainly sedative effects.

Acute Neuroimmune Effects of Alcohol Using Free Water Imaging
Alcohol DrinkingThis study examines the effects of moderate alcohol intake on the brain, the immune system, and cognition.

Self-estimates and Objective Blood Alcohol Concentration in Emergency Department
Alcohol Use DisorderBlood Alcohol ContentMany patients presenting in Emergency Department (ED) present alcohol acute intoxication. Some previous studies in general population found that young people under- or over-estimated of blood alcohol concentration (BAC). The hypothesis of the study is that self-estimation of BAC by the patient is under-estimated. Moreover, comparing self-estimation of BAC and objective measure of BAC, which is routinely performed in ED, could increase in patients the awareness of the disorders, increase motivation to change of the patient, and increase the rates of seeking-treatment six months after the first evaluation, in particular in patients with alcohol use disorders. To the investigators knowledge, there is no study investigating self-estimation, compared to objective measurement of blood alcohol concentration in patients with alcohol intoxication presenting to an Emergency Department (ED). The study will assess blood alcohol concentration and self-estimates of BAC, using the Subjective Effects of Alcohol Scale for Measuring Subjective Response to Alcohol in 100 patients with or without alcohol use disorders according to DSM-5 classification (using MINI scale and Alcohol Use Disorders Identification Test (AUDIT)

Role of BP1.3656 on Alcohol Responses
Alcohol Use DisorderThe current study will determine whether a novel pharmacotherapy, BP1. 3656, affects laboratory alcohol self-administration in participants with alcohol use disorder (AUD).

Design and Implementation of a Drunk Driving Detection System
Transportation AccidentsDrunk Driving2 moreTo analyse driving behavior of individuals under the influence of alcohol using a validated research driving simulator. Based on the driving variables provided by the simulator the investigators aim at establishing algorithms capable of discriminating sober and drunk driving patterns using machine learning neural networks (deep machine learning classifiers).

Understanding Genetic Risk for Alcohol Use Disorder
Alcohol Use DisorderThe purpose of this study is to evaluate an online educational tool that will help individuals better understand alcohol use disorder, risk factors, and genetic risk information and to better understand participant's beliefs regarding alcohol use disorder. This study does not involve genetic testing. Investigators will not be giving participants any personalized genetic feedback as part of the study; however, investigators will ask participants to imagine that they receive different hypothetical genetic risk scores and respond to survey items.
