Well...I don't know whether the radio was defiled or not. That's a
personal issue best left with you and your radio...I have no interest
in knowing what the two of you do with the lights out.

I do know that radios that were used by smokers do accumulate the tar
and other residue left over from burning tobacco leaves. The result
smells like a combination of the clothes smokers wear and an old ash
tray that needs cleaning. Also, the tar does have an effect on
electrical components.

I'm not sensative to smoke, but I'm certainly sensitive to it - the
odor is obnoxious. When the odor is combined with an awareness of what
it does to the human body the habit becomes downright repulsive. I've
never understood why smokers feel it necessary to smoke while driving
with the window down and why they feel it necessary to drop ashes and
burnt cigarettes everywhere. Why not close the car window and get
fully enjoymant of all that smoke - I'm sure nobody else wants to share
it. And put the ashes in a cup or maybe an ashtray.
