what effect does smoking have on the number of red blood cells?

Answer 1

The number of RBC's could remain unaffected by smoking over time however changes in the amount of smoking can alter its count.

There are also few research findings stating that a change in the smoked amount can result to a decrease in RBC count to some extent.
