I know some people who smoke two or three times a day (not medical users either.) But they're still functioning at their jobs and in school. I smoke too, but not near as often as these folks do.
Is it too much even though they're still functioning?
For that matter, how often is too often, and how much is too much?
(I don't know if I have this question in the right category or not, but thought I'd ask anyhow.)
