Cigarettes actually are uniquely bad when it comes to lung cancer. Lung cancer was very rare in 1900 and before when everyone was still burning wood or coal for warmth and cooking. Lung cancer rates didn’t take off until cigarette popularity exploded after WWI.
Chewing tobacco also causes mouth cancer, so there’s more to it than just inhaling byproducts of combustion.
