"Clear and lucid" isn't a phrase I'd use, and when I haven't had a smoke for a while I generally don't really notice it - for me it's more about habits than physical withdrawal symptoms. The chemical thing that I love is the slight rush a cigarette brings if you haven't smoked in a while.
Cigarettes are obviously bad and a stupid thing to do, but there are people (including myself) who genuinely enjoy them, we aren't just addicted and using them to get back to level zero.
Spot on! The only time I smoke is on a Friday night with a pint of ale and I enjoy smoking my weekly roll ups far too much to consider quitting. I know the health risks, but when I live in London and inhale car fumes for an hour whilst cycling to and from work everyday, the pleasures I get from smoking few cigarettes on a friday night exceed the health implications by a long way!
