Many factors affect an individual's absorption of alcohol including:

The absorption of alcohol in an individual's system can be significantly influenced by gender and body weight. These factors play crucial roles in determining how much alcohol enters the bloodstream and how the body metabolizes it.

Gender affects alcohol absorption due to physiological differences. Generally, women have a higher body fat percentage and lower water content in their bodies compared to men, which typically leads to higher blood alcohol concentration (BAC) levels for the same amount of alcohol consumed. This means that women may feel the effects of alcohol more intensely and quickly than men.

Body weight is another vital factor in alcohol absorption. Individuals with a higher body weight generally have a larger volume of water in their bodies, which can dilute the alcohol in their system. Therefore, two individuals of varying weights consuming the same amount of alcohol may experience different effects; the heavier individual may have a lower BAC compared to someone who weighs less.

Together, these factors illustrate why understanding the individual's gender and body weight is essential in assessing alcohol absorption and its effects.
