The liver filters everything that goes into your body. The chemicals from smoking may not get a first pass through the liver as if you'd eaten them but smoking is not liver friendly.
hecky,
it can also have effect on liver too. Why would you want to give your liver any extra work when it is lying there in your body knackered already trying its hardest to fight on your behalf!!!! Give it some help. QUIT SMOKING.
It will be difficult but well worth it.

Obviously, it is bad.. it effects the lungs, not the liver.
