Acute Effects of Jägermeister With Energy Drinks (Jägermbomb)

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Alcohol Drinking, Healthy Adult Participants, Binge Alcohol Consumption, Energy Drinks

In brief

The main objective of this study is to compare the acute effects of drinking Jägerbombs with drinking alcohol alone during a binge-drinking episode, which involves consuming a large amount of alcohol in a short period of time to become intoxicated. Secondary objectives are to assess whether Jägerbombs produce prototypical alcohol effects, increase stimulation and rewarding effects, affect coordination, time reaction and vision, change stress-related hormone responses, and cause hangover symptoms.

• Understand and agree to the trial procedures and sign an informed consent.
• History and physical examination that demonstrate no organic or psychiatric disorders.
• The ECG and general blood and urine tests performed before the test should be within normal limits. Minor or punctual variations from the limits of normality are allowed if, at the discretion of the Principal Investigator, taking into account the state of science, they are not of clinical significance, do not pose a risk to the subjects and do not interfere with the assessment of the product. These variations and their non-relevance will be justified in writing in a specific way.
