Okay, this is pretty close to a nitpick, but the chemist in me refuses
to let me let it pass.
Surface contamination in a geometry like that is a
pretty good suspect$
Nicotine is not actually a hydrocarbon; the molecule has two nitrogens.
Also, most of the gunk deposited on things subjected to tobacco smoke
is not nicotine; it's assorted incomplete-combustion products.
This is not to say that smoke deposits couldn't cause the symptom
described; I would expect they could. Just that it's probably not
nicotine that's responsible - and that nicotine isn't a hydrocarbon.
