Alcohol metabolism and physiological impacts

Information regarding alcohol metabolism highlights the various factors that influence how long it takes for the body to process alcohol, including sex, weight, metabolism, and the quantity and speed of consumption.

Medical and safety data indicate that alcohol is absorbed through the digestive system into the bloodstream, where the liver utilizes enzymes to convert it into water and carbon dioxide for excretion. The rate of consumption relative to the liver's processing capacity determines Blood Alcohol Concentration (BAC) levels.

Estimates for metabolizing specific drinks vary: a single glass of wine takes approximately 3.5 hours, five glasses can take over 17 hours, a single beer takes about 2.5 hours, and a single shot of spirits takes roughly 1.5 hours. Alcohol can remain detectable in the blood for up to 12 hours, in urine for 12 to 24 hours, and in exhaled breath for up to 24 hours.

Experts warn that alcohol impairs driving by narrowing visual fields, slowing reflexes, and causing misjudgments of speed and distance. There is no known way to accelerate the metabolic process; the only safe method is to allow sufficient time for the body to process the substance.
