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 compares two ways to help people who are in treatment for substance use also quit or reduce smoking: using e-cigarettes or using standard nicotine replacement therapy (like patches or gum). If you're ready to make a change in your smoking, this could be a helpful option.

This study tests a program called VergeRx that helps smokers who aren't ready to quit reduce their smoking. You'll get support and use nicotine patches and lozenges to help you smoke less.

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.
