Smoking

Hmmmm..........Did you ever spit on a lighbulb before? While the light was on?

 

Eventually your fingers will turn yellow from the nicotine.

 

even though it's the most mildly neurotropic of neurotropic substances, tobacco is also the most physicly addictive. more so then even the 'hardest' of 'hard' drugs, with the possible exception of the opiates.

none of which was that much of a real problem as long as it was only used ritualy, rather then mass consumed recreationaly, as was the case
before the first terrorist invasion of the western hemisphere half a milinia ago.
