Passive Smoke could harm your Health

Passive smoking has been demonstrated to have harmful effects in people.

But the risk of passive smoking has been widely recognized during the recent year. Passive smoking constitutes a serious public health risk to both children and adults.

Scientists also found that isoprostanes, a reliable marker of in vivo oxidation injury, have been shown to increase in active cigarette smoking.

Cigarette smoking has been shown to be associated with a significant increase in 8-epi-PGF2 α, a major member of this family of compounds. Quitting smoking reduces 8-epi-PGF2 α values to normal within a couple of weeks only. Researchers from Austria and Greece examined the 8-epi-PGF2 α, values in plasma, serum and urine in 12 smokers and non-smokers who were exposed to daily passive smoking.

They found that 8-epi-PGF2 α shows a higher increase in cigarette smokers.

But exposure to passive smoking caused a significant increase in 8-epi-PGF2a in non-smokers, while in smokers there was only a trend wise increase. After repeated passive smoke exposure, 8-epi-PGF2a in non-smokers approached the respective values of smokers.

The increased level of isoprostane is one of the underlying mechanisms contributing to increased risk of heart attack in patients taking Coxibs (a subclass of no steroidal anti-inflammatory drugs designed to inhibit selectively cyclooxygenase-2).

Apparently, repeated but not single exposure to passive smoking introduces a significantly large number of radicals into the human body. After rapid consumption of antioxidants lipid peroxidation products including isoprostanes are accumulated in blood and finally in vascular tissue exerting harmful effects

To continue to smoke and put the health of your family and loved-ones at risk would seem, on the face of it, to be a rather selfish act. When you take into account the damage that smoking is doing to your own body then it seems more like insanity. Think of how traumatic it would be if a member of your family became ill or died because of your smoking habit.
