Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

E-cigarette (EC) use continues to increase among youth, and EC may be detrimental to youth respiratory health. Public health officials and the Food and Drug Administration (FDA) can now regulate ECs. The proposed study uses naturalistic assessments called ecological momentary assessment (EMA) to understand how ECs use may impact the respiratory health of youth and young adult users compared to never-using peers.
