<qa>  How many HIV-infected individuals on effective ART will be recruited?For Aim 2, a total of 100 HIV-infected individuals on effective ART who are active smokers and interested in participating in a smoking cessation program will be recruited. If 20 individuals who achieve 10-week of cessation are enrolled before 100 HIV smokers are fully enrolled, enrollment will cease, as 100 participants is an overestimate of the number of patients needed need to enroll to have 20 subjects achieve successful smoking cessation. The maximum total number of patients needed for the grant is 120 100 HIV smokers, 20 HIV non-smokers.
