What factor influences the B.A.C level?

Blood Alcohol Concentration (B.A.C) levels are influenced by several factors, including the amount of alcohol consumed, the rate of consumption, body weight, and metabolism. Additionally, factors such as age, gender, and food intake can also affect how alcohol is processed in the body. For instance, consuming alcohol on an empty stomach can lead to a quicker rise in B.A.C compared to drinking after a meal.
