This article published on 1st July 2008 say it all. What you and I have been saying for many years. It is written by a "pulmonologist", that must be an american lung specialist. Not necessarily a medic but defo a scientist. It is published in "Environment and Climate News" by the american "Heartland Institute". It very neatly summarises all the available information and correctly identifies how 80% of the American and worldwide public have been duped into believing second hand tobacco smoke can harm non-smokers.
Passive smoking does no harm at all..RIP "Passive Smoking"
