Quitting smoking may also ward off diabetes — a trial puts the dual strategy to the test
NCT ID NCT01926041
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This trial investigates whether a smoking cessation program that also helps control weight can reduce the risk of developing type 2 diabetes in people who smoke and have prediabetes. Participants receive varenicline (a quit-smoking medication) along with personalized coaching on diet and physical activity. The study tracks how many go on to develop diabetes versus return to normal blood sugar levels.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- a smoking cessation drug called varenicline plus behavioral coaching on diet and exercise
- What this could lead to
- If successful, this approach could help prediabetic smokers quit tobacco while avoiding weight gain, potentially preventing or delaying type 2 diabetes.
- What could go wrong
- This is a single-center study, and results may not apply to all smokers. The program combines drug and behavioral support, so it is unclear which part drives any benefit.
