A statistically insignificant reduction to the world population of smokers. Without laws to prevent tobacco marketing to minors, the cigarette industry could add 100x as many customers in a day.

But if one person in an average household quits that is a 25% reduction.

In the end that person and those around benefit.

There are 4 smokers in an average household?!
