Well, they're making it sound like secondhand smoke is worse than firsthand. With GW they're making it sould like CO2 is a worse pollutant than CO.
I always wondered how they came up with that one. Since the smoker is always the closest to the smoker (himself) he gets both the firsthand smoke AND the secondhand smoke. If that's safer than the guy a few feet away getting just the secondhand smoke, then that would imply the firsthand smoke is actualy improving his situation!
