 Sorry to be Dr. Buzzkill, but alcohol appears to be humanity's seven leading cause of death and disability. The safest level of drinking is none. But wait a second, what about the famous J-curve, where light to moderate drinkers appear to have lower mortality rates than the T-totalers at zero drinks a day? This may just be an artifact of the systemic misclassification of former drinkers as lifelong abstainers. This leads to the so-called sick-quitter effect, where the reason a person may be a non-drinker is because drinking made them sick, thereby making current drinkers look good in comparison. It's the same reason studies can find higher mortality among those who quit smoking compared to those who continue to smoke. It's not that abstention led to poor health, but poor health rather led to abstention.
