 In another study which looked at subjective responses to alcohol as a prime for 21st birthday alcohol consumption, subjective responses to the initial drink were viewed as a prime for more alcohol consumption during 21st birthday celebrations.Current findings show that subjective responses to alcohol have direct effects on both the final BAC achieved and on the experiences of blackouts and hangover that are not explained by level of intoxication.Where a variety of social factors, such as peer pressure and 21st birthday traditions such as 21 shots may influence the amount of alcohol people consume, their subjective experiences with alcohol have clear influences on both consumption and the physiological consequences of drinking.
