Now you start to see how you can get to the number that billions of people are consuming tobacco. Because of course you also have your people that are dipping and your people that are snuffing.

Anywhere from one eighth to a quarter of human beings are consuming tobacco in one form or another in order to get their nicotine one way or another.
