What's worse health wise:?

Cigarettes or weed? I always thought cigarettes were worse because they have been known to be linked to lung cancer, emphysema and other health problems and they blacken and damage the lungs and you don't get a high, whereas with weed you do get a high and you don't usually get cancer from it. And it's a herb, whereas cigarettes are filled with over 4,000 chemicals. But obviously, legally weed's worse because you could get busted for it, whereas you don't with cigs. But what do other people think?
