Helping people experiencing homelessness quit smoking

This early-stage study tests ways to help adults who currently smoke daily start making progress toward quitting (or changing smoking habits) over the next 6 months. You may use nicotine replacement, and the study checks safety for people who can use it.

This study tests whether nicotine replacement therapy (like patches or gum) can help people living with HIV quit smoking. You'll be part of a program that supports your quit attempt while you receive care for HIV.

This study tests whether switching to a less harmful nicotine product (like a nicotine pouch or e-cigarette) can help people who are not ready to quit smoking reduce their health risks. You would be given a sample of a harm reduction product to try, and researchers will check how it affects your smoking habits.

This study tests whether switching to e-cigarettes or nicotine pouches can help smokers who have tried many times to quit. If you are a heavy smoker (at least 5 cigarettes a day) and have failed to quit before, this trial may offer a new way to reduce harm from smoking.

This study tests a program to help veterans who are homeless quit smoking by offering rewards for staying tobacco-free. It aims to see if this approach helps more veterans quit than standard support.

This study tests a program meant to help people stop smoking after they leave a psychiatric hospital. It may help you stay smoke-free longer by offering structured support during a high-risk time.
