Fewer kick light cigarette habit

The American study that this article reports on found that “light” cigarette smokers were 50% less likely to quit.

While we’ve known for some time that light cigarettes are not safer, this runs against the conventional wisdom. I think most people would have guessed that smokers of “stronger” or unfiltered cigarettes would fare the worst.

It would be interesting to see some analysis of possible reasons for this. Is it based on gender? The article mentions that most of the light cigarette smokers are women. Does switching to light cigarettes represent a commitment to smoking by trying to do it more safely? (However misguided this notion is.)
