How long does it take to repair from second hand smoke?

Depends. Susceptibility to the harmful effects of tobacco varies greatly among people. People with a genetic deficiency in an enzyme inhibitor called alpha 1 antitrypsin may develop emphysema at an early age yet others may never have any noticeable problem at all. Since there is no upside to tobacco exposure, avoidance is the only logical answer.

For how long will it take to recover from second hand smoke exposure?

Tobacco smoke. We all slowly lose lung function as we grow older, typically most non-smokers will die with greater than 80% of their lung function. Smokers lose lung function at a faster rate. If they stop, the rate of decline typically slows to the same rate as non-smokers. Most people do not experience activity limitations until they have less than 80% capacity. Read more...

How much time does it take for second hand smoke to effect you?

No easy answer. To that question, for several reasons. Depends on the amount of second hand smoke. If you work in a bar or restaurant that allows smoking, you are exposed to high levels of smoke, and relatively short-term exposure could cause harm (respiratory infections, asthma). If it is milder exposure, it may take many years to cause any detectable harm. Read more...

If you get black lungs from second hand smoke, how long will you live for?

Won't happen. The pigment isn't the problem. If second-hand smoke exacerbates your asthma, it can be minutes -- hundreds of kids die of this in the us each year. If you get a lung cancer from it -- and there's a few thousand yearly though uncle sam's old figures are way inflated -- it will take the same time as a smoker -- months to years. Read more...

How long could cotinine stay in blood and urine after being around second hand smoke?

About a week. Cotinine has an in vivo half-life of approximately 20 hours, and is typically detectable for several days (up to one week) after the use of tobacco. Cotinine levels <10 ng/ml -non smoker 10 ng/ml to 100 ng/ml are associated with light smoking or moderate passive exposure and levels above 300 ng/ml are seen in heavy smokers. Read more...
