Ethanol, the primary component in alcoholic beverages, undergoes a metabolic process in our bodies. As it breaks down, it produces acetaldehyde, a compound that is then further processed by enzymes known as dehydrogenases. It used to be thought that moderate alcohol consumption confers health benefits, but experts now recognize that regularly imbibing can have a variety of harmful health consequences. “It can exacerbate depression, increase blood pressure, and lead to cardiac arrhythmias,” Koob says.

Adding a four‐ or five‐plus initial drinking quantity threshold marginally improved the percentage change‐based definitions strength of association with new onset AUD. However, the difference in effect sizes were very small, and should be replicated in larger, more diverse samples. Alcohol tolerance is both a cause and symptom of alcohol use disorder.
