a For example, the U.S. Department of Health and Human Services defines high-risk drinking as “the consumption of 4 or more drinks on any day or 8 or more drinks per week for women and 5 or more drinks on any day or 15 or more drinks per week for men.” Standard drink sizes vary by country, so consult your health-care provider to confirm what is considered a low-risk drinking limit for you.
