Smokers have a greater chance of developing deadly diseases

The question is the following: "Smokers have a greater chance of developing deadly diseases" and I assume we are asked to determine whether it's true or false. It is a true statement - and we can see it on the packaging of cigarettes in many countries. Some of these diseases are cancer (for example lung cancer) and diseases of the blood stream.

As far as I know I would think that the answer would be true cause you can get lung cancer and other things related to that a lot easier.
