The other very unfortunate thing that cigarette smoking causes--and it's not as well publicized as the other conditions like cancer or heart disease or high blood pressure but it goes right along with poor vascular health--is erectile dysfunction. My husband is asked to prescribe Viagra or something like it at least twice a day by his patients. Smoking leads to problems in the bedroom for many, many men, and yet a huge number of them aren't aware that it can have that effect, too.
