This is almost certainly not true, and seems illogical. I read about a study done in Britain which measured levels of smoke inhalation, and it concluded that working in an office of regular smokers was the equivalent of smoking about five cigarettes
a year. Once exiting your mouth, smoke starts immediately dispersing exponentially. Being mere feet away, you would still only get the tiniest fraction of the level of actual smoke (though unfortunately the smell is still there).

Well, I got that one from a TV-show about smoking.
This almost made me lol. I am sure that TV show had no biases at all.

Basically, what the smoker breath out contains a ten times higher % of the dangerous particles in the smoke that may cause the side-effects.
How does the smoke which a smoker breathes in -- through a filter -- magically become more dangerous upon exhalation? Again, fails a common sense test. I doubt even "ten times" more dangerous would make much of a difference, considering the thousands, millions of times smaller the exposure is (unless you did something like kiss and blow it into the other person's mouth, which is really, really gross and I regret coming up with it).
