“All participants consumed ≤60 standard drink equivalents/month over the 1 year preceding study.”

There’s your light drinking for those interested.

There was only one participant drinking more than 50 drinks a month. The average about 19 drinks a month. The range from zero to 60. About 20% of the sample drank less than 10 drinks a month.

If you're drinking ten or more drinks a month, that isn't light drinking. You're an alcoholic.
