NIAAA defines heavy alcohol use as follows:

For men, consuming five or more drinks on any day or 15 or more per week

For women, consuming four or more drinks on any day or eight or more per week

According to the 2024 NSDUH, 14.4 million adults ages 18 and older (5.5% in this age group) reported heavy alcohol use in the past month

Five drinks for me would be a good date night dinner at home (cocktail hour, plus two glasses of wine with dinner). Hardly a bacchanal, but apparently America is slacking as of late.
