Brief Summary

Cigarette smoking is very common in current and former injection drug users and is known to cause chronic lung diseases. Quitting smoking is proven to improve the health of people addicted to cigarettes. . Little information exists regarding the perceptions and characteristics of drug users regarding quitting smoking. Additionally, most programs designed to help people quit smoking are not very successful. One reason these programs may not work well is because it is difficult to motivate people to quit smoking. New methods of motivating changes in behavior include small monetary payments for healthy behavior and reporting breathing tests with the concept of "lung age," which is the age of an average healthy person with similar breathing test results. For example, a health care provider can report results as "Although you are 50 years old, you have the lungs for a 70 year old". In this proposal, the investigators plan to first explore the beliefs and characteristics of current and former injection drug users and how they are related to quitting smoking. The investigators then plan to study whether the use of two new methods of motivation increases the chances that this group will stop smoking.

Primary Outcome Measures

Name	Time	Method
Biologically confirmed tobacco cessation	6 months	The primary outcome will be validated tobacco cessation at 6 months. Biologically confirmed tobacco cessation will be assessed by self-report of smoking status combined with CO measurement.

Secondary Outcome Measures

Name	Time	Method
Self efficacy and intention to quit	6 months	Self-efficacy and intention to quit smoking will be assessed at baseline using a modified version of the Prochaska stages of change questionnaire. Quit attempts will be enumerated at follow-up visits by asking participants how many quit attempts they made in the prior six months.
Cessation attempts	6 months	Cessation attempts will be quantified as the number of sustained cessation attempts lasting more than 7 days, number of sustained cessation attempts lasting more than one month and number of daily cigarettes smoked.
