Major finding: 15% of smokers under age 50 years have signs of COPD.
Study details: Danish population cohort (n = 105,630).
Disclosures: The study was funded by the Lundbeck Foundation. One of the authors has received support from the NIHR Manchester Biomedical Research Unit. Dr. Reed has no relevant financial disclosures.
