Though alcohol is not good for the body, a few drinks can be helpful if taken in appropriate degree. For example red wine when taken in lesser quantity may help your skin to look younger as it contains resveratrol that is beneficial for the skin. However, if wine is consumed in surplus quantity it may also have some disadvantages or harmful effects on the body.

BAC or Blood Alcohol Content:

It is known by all that alcohol, after consumption, remains in the body for certain amount of time. The time required for alcohol to leave your body system may depend on the quantity of alcohol that is consumed by you. The degree of alcohol that enters into the blood stream is known as BAC or Blood alcohol content. Factors that influence the blood alcohol content of an individual are sex (gender), number of drinks, body weight of the person and the time of consumption of the drink. For an instance, if a female weighing 140 pounds consume 4 drink of alcohol with 3 hours, her BAC will be .094; whereas if same number of drinks is consumed in same time by a 200 pounds man, his Blood Alcohol Content would come to .041.

Alcohol in the body:

You body starts to metabolize the alcohol when it is consumed. During this process of metabolizing, the alcohol enters into the bloodstream and eventually travels throughout your body through all your organs along with the blood. The alcohol in the body is excreted to some extent through breath, urine and body sweat. For the alcohol to enter into blood it takes sometime after consumption. The alcohol that is not excreted through any of the aforementioned sources retains in your blood; hence, many times alcohol screening tests may need a blood sample. If your breath is tested one or two hours post consumption, then your alcohol content may not be detectable. This may also depend on your weight, gender and how frequently you consume alcohol.

All kinds of blood test may detect some degree of alcohol even if conducted after a long period of time. Some degree of alcohol, like 1 to 3 ounces may be noticeable through blood tests in your circulatory system even after 10 to 12 hours of consumption; this is incase you drink alcohol occasionally. In case if you are habituated to alcohol, your body may store alcohol from previous drinking event; hence, it may take significant amount of time for your system to completely excrete alcohol. Sometimes it may also take up to seven days for the alcohol to leave your body completely.

By now you must have understood that alcohol affects each consumer differently, which is why the amount of time it takes for alcohol to leave your body system completely may vary from individual to individual.  A person who consumes alcohol quite frequently may build up resistant for processing alcohol. This is why a heavy alcoholic person’s liver may tolerate three times more drinks per hour. One ounce of alcohol may have significant effect on a petite woman as compared to man wherein effect of alcohol may not be significant. The retention of alcohol in such female may also be for a longer time as their body’s metabolization ability will be different.
