L-QUIT

Why this project is done 

Nicotine vaping has increased rapidly among young people and is now more common than cigarette smoking in adults ages 18–25. Many young adults who vape say they want to quit — but there are very few programs designed specifically to help them. 

This study is testing a new smartphone-based app designed to help young adults quit vaping. The program uses technology to provide real-time support — especially in places where someone may be more likely to vape. 

 

What This Project Does 

  1. Delivering Support at High-Risk Moments 

  • The app uses location technology (GPS) to detect places where a person has previously vaped. 

  • When the person enters one of these locations, the app sends a supportive message encouraging them to avoid vaping. 

  • The app also checks in throughout the day, asking brief questions about stress, cravings, mood, or surroundings. 

If someone reports high stress or strong cravings, the app sends a message tailored to that specific need — such as a stress-management tip or a short distraction strategy. 

We will evaluate: 

  • How well the app works in daily life 

  • Whether people use it consistently 

  • Whether the location-based alerts are accurate 

  • How easy it is to use on a smartphone or smartwatch 

  1. Learning From Participants 

After the 30-day test, 15 participants will join virtual interviews to share their experiences. 

We will ask about: 

  • How often they used the app 

  • Whether the number of messages felt manageable 

  • Whether the messages were helpful 

  • Any privacy concerns 

  • Suggestions for improvement 

 

Why This Matters 

Young adulthood is a key time when occasional vaping can turn into long-term use. Providing support during this critical period may help prevent long-term nicotine addiction. 

This project explores a new approach called “just-in-time support” — meaning help is delivered exactly when someone may need it most. If successful, this program could offer a practical, personalized way to help young adults quit vaping and protect their long-term health.
