Also would they drink tap water? I'm sure they do.
Would they watch TV? I'm sure they do
How about breath air that is in/around chemtrails? You betcha!
All sounds kinda silly when you look at the big picture, huh?
You're right, King Harald has quit smoking since his cancer diagnosis. If you go to the Norwegian forum under the latest King Harald and Queen Sonja News thread, there is an article about how he quit and how he feels about it.
There is also the infamous incident of Queen Margrethe lighting up while visiting a cancer ward. The article even made it to non-royal publications such as People Magazine here in North America and some newspapers here in Canada.
Some other royal smokers to add to the list: Prince Henrik Prince Joachim Crown Prince Haakon Prince Ernst August Prince Harry Lord Frederik Windsor Princess Marilene of the Netherlands (wife of Prince Maurits) Prince Johan Friso Not royal, but royal-affiliated Pierre Casiraghi (Does sister Charlotte smoke, too?)
Camilla Parker-Bowles - used to smoke, but has since given it up because Charles finds it to be a "filthy" habit I have also heard that Infanta Elena smokes, though I have never seen a picture.
