Leukocytosis is a condition that causes you to have too many white blood cells (WBC). WBCs are part of your immune system and help fight infections and diseases.

Do not smoke.

Nicotine and other chemicals in cigarettes and cigars can cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your provider before you use these products.
