Further Information

Regardless that the quantity of toxins in passive smoking are small enough to be harmless and that the credo that “there is no safe level of exposure to passive smoke” is a bad joke meant to further prohibition policies, there is no question that, given the psychological situation created by antismoking propaganda, the smell of tobacco has become a real annoyance for some. It must be noted that passive smoking was not even noticed by non-smokers thirty years ago because they were not subject to the hammering effects of propaganda. Thus they considered the scent of tobacco as perfectly normal and unobjectionable.

This meta-analysis of studies by the Chartered Institution of Building Services Engineers (CIBSE) highlights the most feared (thus hated and “prevented”) thing by prohibition advocates: that ventilation and air conditioning systems are actually effective in removing passive smoking and its scent. In fact, it is exactly for that reason that the “there is no safe level of exposure” slogan was manufactured. The antismoking advocates know well that no machine can be 100% efficient, as that is a physical impossibility; so, the “no safe level” applies to machines that can actually remove 99.7% of the substances, since the residual 0.3% from an absolutely infinitesimal amount of toxins in the first place still constitutes a risk for “health”, as the only number acceptable is 0.00!
