I don't know. It's like the difference between smoking cigars and cigarettes. However, it does take the "green" status of ethanol down a notch.

This ozone concern has me wondering about complaints from Camry owners regarding the "sweet" smell from their vents and the Ionizer. I suspect that ozone is entering the cabin. I know the odor is initially perceptible at one tenth the safety limit, which makes it difficult to know if the occupants are being exposed to an unsafe level.

Here are a couple of sites for more info on ozone.
