What’s Blood Alcohol Concentration (BAC)
% of alcohol in blood

-Rate of consumption
How weight effects BAC
alcohol has stronger impact on less heavy people
How gender effects BAC
Woman get drunk faster because

How food consumed effects BAC
If you eat food you process alcohol slower because the body has to process food so alcohol can’t be processed into bloodstream as fast
