Brief Summary

Cigarette smoking is more prevalent (50-70%) in persons living with HIV in the U.S. when compared with the general population and is linked to increased rates of heart disease, lung diseases and infections, and lung cancers. Because of their high levels of nicotine dependence, low quit rates, and familiarity with harm reduction, HIV-positive smokers may view the use of alternative nicotine delivery products, such as electronic cigarettes (ECs), as an attractive option for reducing and eventually stopping combustible cigarette use. However, little is known about the health effects of electronic cigarette use in HIV-positive smokers. Some studies have shown that electronic cigarette use was associated with increased confidence to quit smoking in the general population. The primary objectives of this project are to examine whether HIV-positive smokers, who are unwilling or unable to quit smoking, will substitute an electronic cigarette for regular cigarettes, and to examine whether there are any changes in heart and lung health in HIV-positive smokers who switch from regular cigarettes to electronic cigarettes.

Study Arms (2)

Active condition

EXPERIMENTAL

Participants in the active condition will be provided with the Standardized Research Electronic Cigarette (SREC) and will be encouraged to use the SREC whenever they would normally smoke a cigarette.

Device: Standardized Research Electronic Cigarette

Standard Condition

NO INTERVENTION

Participants in this condition will be asked to continue to smoke their usual brand of cigarettes.

Interventions

Participants will receive SREC weekly and eill be encouraged to replace their usual combustible cigarette with the SREC whenever they would normally smoke.

Model Details: Once the baseline interview is complete, the study coordinator, who is not involved in conducting assessments, will randomize eligible participants to either of two study conditions. A computerized urn randomization will be used to ensure the groups are balanced on gender and Fagerström Test of Cigarette Dependence (FTCD) score, (0-5 low; 6-10 high). Participants will be randomized to an active condition (in which they will be provided with the ECs) or the standard condition (in which they will continue to smoke their usual brand). All participants will receive a daily diary and will be asked to record daily how many CCs they smoke, how many EC cartridges they use, or any use of other tobacco products (i.e. cigars, cigarillos).
