A total of 2,921 HIV patients and 10,642 controls were followed for 14,281 and 45,122 person-years; this is a big, rigorous study.
A 35-year-old HIV patient had a median life expectancy of 62.6 years (95% CI, 59.9-64.6) for smokers and 78.4 years (95% CI, 70.8-84.0) for nonsmokers
The numbers of life-years lost in association with smoking and HIV were 12.3 (95% CI, 8.1-16.4) and 5.1 (95% CI, 1.6-8.5).
Not smoking is one of the easiest things you can do for your health. Once you are past quitting and withdrawal it costs nothing and takes no effort. It also increases the size of the dating pool.
