Carbon monoxide is a byproduct of cigarette smoke. The bond of CO to hemoglobin is 100 times as strong as the O2 bond so CO does displace O2 in the blood. Just don't understand why, if we're short of O2, the vessels don't dialate instead of constrict. Doc Greg straightened me out the other day on some serotonin thinking. I wasn't seeing the whole picture. Maybe one of the other chemicals in tobacco smoke, nicotine maybe, is what causes the constriction. So double whammy. Low O2 and constriced vessels.
Whatever. It ain't good for ya and one of these days I'm gonna quit smokin' cigars. For right now, way to go Drummer. Stay off em for as long as ya can. You're doing the right thing.
