What effect does smoking have on your CD4 count and percentage? A pack a day.
Response from Dr. Holodniy
Little data is available to answer the question directly. It does not appear that smoking affects CD4 number, but some animal data suggests that nicotine alters some of the important chemicals and hormones that CD4 cells make. This could affect CD4 function and therefore the way the immune system controls HIV infection.
