Summary

This trial will test whether providing incentives for smoking cessation (like cash) to people experiencing homelessness makes them more likely to quit smoking.

Who is the study for?
This trial is for homeless adults who smoke daily, have smoked over 100 cigarettes in their lifetime, and want to quit within six months. They must be getting or willing to start smoking cessation counseling at the Tom Waddell Urban Health Center, be over 18 years old, meet homelessness criteria, and speak English. Pregnant individuals or those with a recent heart attack can't participate.
What is being tested?
The study tests a contingency management approach that rewards quitting smoking with cash incentives among the homeless. It aims to see if this method is practical and well-received when offered through safety net clinics.
What are the potential side effects?
Since this intervention involves behavioral changes rather than medication, there are no direct side effects like you'd expect from drugs. However, participants may experience typical nicotine withdrawal symptoms such as irritability, cravings, or difficulty concentrating.
