Background
Alcohol is a risk factor for more than 200 health problems, yet it is the most widely consumed psychoactive substance globally [Warning labels on alcoholic beverages are currently implemented in 47 countries [The regulation on health warning labels for alcoholic beverages in Mexico is also limited. The regulation has not been updated since 2014 and establishes that alcohol containers must include a cautionary legend (Evidence from randomized trials –mainly online studies from the United Kingdom, Australia, and Canada– suggests that health warning labels on alcoholic beverages that are visible and up-to-date can impact a range of outcomes beyond raising awareness, including product attractiveness, visual avoidance, and intention to change consumption [To our knowledge, experimental studies have not been conducted in Mexico to evaluate the impact of health warning labels on raising awareness about health risks, attitudes, and behavioral intentions.
