SWAP Trial Summary

This trial will test whether adults with asthma who smoke cigarettes will substitute ENDS for cigarettes, reduce dependence, and improve lung function.

They must have used short-acting bronchodilators, show signs of smoking on a breath test, and understand English well.

What is being tested?
The study is testing whether using e-cigarettes (ENDS) helps adults with asthma switch from smoking regular cigarettes, become less dependent on nicotine, and improve their lung function. The goal is to see if e-cigarettes can reduce the harm caused by tobacco in people with respiratory issues.See study design
What are the potential side effects?
Possible side effects may include throat irritation, coughing, dry mouth or throat due to vaping; nicotine dependence; and potential unknown long-term impacts of using ENDS as an alternative to traditional cigarettes.
