That’s more like a therapeutic/occasional recreation dose and habitual users consume it multiple times a day.

A survey found that average daily consumption was 0.9g and median 0.35g.

92lb=41.73 kg = 41730g / 0.9g / 365 =127.032 average-user-years. Or basically a month’s supply for a small town.

Like most consumption, the top 10% easily account for >80% of total consumption.
