WHO proclaimed, "Second-hand smoke is a real and significant threat to public health. Supported by two decades of evidence, the scientific community now agrees that there is no safe level of exposure to second-hand smokeWhat a bunch of bullmodell. Just about any workplace toxin is regulated by what is called a "permissable exposure level", or a PEL for short. There's often both an instantaneous PEL and an 8-hour average PEL.
There are a few chemicals that have PELs which are effectively zero. They are so nasty that if you were to get a concentrated dose of them, you'd need either an ambulance or a coroner immediately. Yet people ingest concentrated amounts of tobacco smoke not only routinely, but for long periods of time.
This statement insults the intelligence of anyone with the slightest clue about how either chemical-related occupational safety or basic toxicology works. Quite clearly, if someone can puff away all day, the mere smell of a cigarette isn't going to make anyone else sick, except perhaps for psychological reasons.
As is the case whenever the left ignores or warps science, the objective is political and anti-freedom.
