What are signs of liver being effected? N is smoking a cause for it? Basically smoking sheesha?

Jaundice. You describe smoking tobacco in a special device to inhale more smoke. I can't recommend tobacco in any form, but this isn't especially likely to affect your liver. Look at the whites of your eye in direct sunlight and if they seem more yellow than usual, or you digestion seems upset, something maybe affecting your liver -- but probably not your tobacco.
