"I doubt that many of those lifetime-but-not-current users tried it only once"

The category is "ever used". If you tried marijuana once, twice, three times -- you fall into that category. Trying marijuana once, twice, three times means nothing. It's a useless statistic.

As you do if you used it regularly for several years but quit over a year ago.

It's a useless statistic.

Overstatement - although other stats would be more useful.

Have you smoked marijuana? How many times?
