Smoke is caustic, the nicotine film attracts dust and thus, static discharges and heat buildup. Imagine what the choker's lungs look like if the radio is soaked with the urine colored film through and through.
KG8LB...not sure what you are talking about re: "the current administration"
if you are referring to President Obama, he himself is a SMOKER! So I don't think he has any business preaching "morals" and "clean living" when the Marlboro Man (Marlboro Reds to be specific) are usually found in his pocket. He did pledge he would not turn the White House urine yellow and only puff outside, but like all drug addicts, the addict will put the dependency above all else. This includes sacrificing health, cleanliness, impact of others in their "smog field", and of course their personal effects (radio equipment and anything else included).
With cancer sticks going to 9 dollars a pack, it isn't going to sway and addict from getting their fix. They will do what they have to do.
Amateur radio gets right through.
