What effect does smoking have on the immune system?
The effects of tobacco smoke on the immune system include: greater susceptibility to infections such as pneumonia and influenza. more severe and longer-lasting illnesses. lower levels of protective antioxidants (such as vitamin C), in the blood.
Does nicotine stimulates the immune response?
Nicotine has been shown to alter immune responses by decreasing inflammation, decreasing the antibody-forming cell response of splenocytes, decreasing proliferation of peripheral blood mononuclear cells, regulating lymphocytes, macrophages, DC, and affecting the secretion of cytokines of lymphocytes.
How does your body react to smoking?
Nicotine enters your bloodstream, increasing your pulse and blood pressure. Your sense of smell is reduced. Because nicotine is a stimulant, your brain will release feel-good chemicals or make you want to eat. When you don’t satisfy the urge, you will feel anxious and irritable.

Are there any benefits of smoking?

What happens to your lungs when you smoke?
Smoking destroys the tiny air sacs, or alveoli, in the lungs that allow oxygen exchange. When you smoke, you are damaging some of those air sacs. Alveoli don’t grow back, so when you destroy them, you have permanently destroyed part of your lungs. When enough alveoli are destroyed, the disease emphysema develops.
