“Life time use” != "use over a long period of time"

In epidemiological surveys, lifetime use == reports using at least once.

Not necessarily. For smoking you need to smoke 100 cigarettes before qualifying for lifetime use.


100 cigarettes seems like a very low threshold, that’s 5 packs of 20, even moderate smokers (>10 per day) could go through 200 in a month.
