Our winters are a little milder than up by the glaciers but still freezing miserably cold. I had a lean-to I would use in extreme weather, also walking the dogs back when we had dogs. They got walked when I needed to smoke.
I used to think my fiancee was exaggerating the need to hang her jacket and blouse out on the porch after a night out at clubs where there was smoking. But the "piety of the converted" argument I get from smokers who care to argue doesn't apply to smoking like it does to food, booze, and other "sins". If someone wants to drink lard it doesn't end up in my lungs.
Smokers are loathe to believe it and will fight the very idea with the focus of the addict: second-hand smoke is assault. It may well be unintentional but the outcome remains.
I remember being a smoker and not appreciating that my personal choice of smoking, outside, in a free country, was threatened by the anti-sinning do-gooders. I have learned by feeling the dry raspy pinch of old smoke right in the gullet. NOT the same as car exhaust, burning leaves in autumn, or any of the other air pollutions out there. There are more chemicals in cigarettes, added during manufacturing as well as bred into the golden light leaf than any of us can legally know. There are paper additives for even burning, glycerin, spices, gasoline derivatives, old tobacco worms, farm workers loogies, pesticides, machine roller lubricant, on and on and on. Not regulated like food. They can have you smoking ANYTHING and paying for the pleasure of more. And the marketing is sickening. Filters became popular in the fifties for the ladies to be able to smoke too, also it made starting up for teens easier.
Good list of some of the approved additives here

Best smoke-free wishes!
