Just quit breathing?

Then there was Rep. Bill Sali, R-Meridian, the House’s Health and Welfare Committee chairman. He told the House, “If we’re concerned about the air, then we all need to quit breathing, because we’re all exhaling carbon dioxide, which is one of the constituents of cigarette smoke.”

Sali may have been thinking of carbon monoxide, a toxic component of cigarette smoke that’s not generally present even in bad second-hand breath.
