alcohol is present in the human body naturally as a result of digestive processes, if it were deadly then evolution would've long since eliminated those digestive processes. just because you intentionally mischaracterize alcohol as "auto fuel" in order to try and make an emotional impact doesn't make it unhealthy. you're confused about the difference between consumption and abuse.
smoking cigarettes has long since been proved to cause no increase in mortality or reduction in life expectancy for anyone who quits smoking before they turn 40. you can smoke as much as you want as long as you quit before you turn 40 and you'll have the same life expectancy as someone who never smoked. life evolved in the vicinities of active volcanoes, wild fires, dust storms, etc. its not so fragile that particulates in the atmosphere harms it substantially even anal retentive personality disorders cause some people to erroneously presume they're entitled to a 100% pristine environment all the time. such a lack of organic environment is unhealthy because it results in weak immune response.
