Yes i am aware of it. BUT I am also aware that it's still a free country and I don't follow the liberal doctrine of criticising every act I don't condone. See exhaust from our cars is harmful too. Butter can be just as deadly as whiskey. Live and let live
Hello; First I am not a liberal. I am not criticising your acts or the acts of others. You have jumped to a defensive position which in not warranted. I also think people should generally be able to do pretty much what they want. The exceptions include those things that affect others.
Smoking for example. I quit smoking many decades ago and now the smell is nauseating and I have a strong reaction to it. I am pleased that I now longer have to risk breathing second hand smoke in resturants. I do not allow smoking on my property but figure you or others can smoke at your place all you want. My problem with smoking is that the expected disease outcomes result in expensive medical care. That many who smoke themselves into such tobacco related disease often cannot pay the cost of that freedom of choice.
My teachers health insurance started making smokers pay a bigger premium rate some years ago. This is the way it should be in that the extra premiums should pay for the greater likely hood of tobacco related disease for the smokers.
Car exhaust is somewhat different. Every car puts out toxic emissions that move around freely to the lungs of others. I was a driver before the first smog controls were placed on vehicles and can recall serious smog. For example if I have a creek that crosses my property onto someone else's property, do I have the right to poision that water when it is on my property?
