Changing nicotine in e-cigarettes to reduce harm
This study tests how changing the amount of nicotine in e-cigarettes affects people's behavior. It looks at two groups: young adults who already vape and older adult smokers who want to try vaping, to see if different nicotine levels can help reduce smoking or make vaping safer.

Common questions
- Are there clinical trials for vaping?
- Yes. Clin2 currently lists 32 recruiting vaping studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a vaping trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a vaping trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
