Since it was invented last century, scientists have discovered that SHS has some really amazing properties.
First and foremost there is its amazing toxicity. Even compared to barbecues and bonfires, second hand smoke is unique in it's ability to cause a heart attack within minutes of exposure.
It is in fact so toxic that it is considered by some to be more toxic than the smoke inhaled by the smoker.
It is immune to wind. Even on an open beach or a public park, wind has no effect on SHS which will spread its toxic cloud evenly across the whole area. It neither disperses nor dilutes.
It can travel through walls and along telephone wires. This surely must be one of its strangest properties? A fire wall between apartments can stop a fire and ordinary smoke but not second hand smoke.
It can detect non-smokers. Yes, you heard that right. Smoke wafting out your window will drift along until it finds an open window whereupon it will head inside again to attack the non-smokers who live there. It even has the ability to travel downwards from a first or second floor balcony to seek out non-smokers at ground level.
In some cases it affects just certain muscles in bystanders. The merest sight of the stuff will cause some people's lip muscles to contract and their hands to wave aimlessly in front of their face.
It has a half life greater than many radioactive isotopes, allowing it to lurk in walls and ceilings for generations, before seeping out and attacking the nearest baby.
It defies the laws of aerodynamics in that the Venturi Effect in a moving car is reversed, and opening a window will actually increase the level of concentration of SHS rather than sucking it out.
It is aware of its surroundings. It will induce cancers in dogs in the home, but not in the laboratory.
Perhaps its strangest and most mystifying property of all though is that it defies itself. It paradoxically has the ability to be both a killer and at the same time to be harmless. It kills tens of thousands of people a year yet has proved to be completely harmless when studied.
It is truly miraculous stuff?
