The CHRNA3 rs1051730 polymorphism has been associated to chronic obstructive pulmonary disease (COPD), lung cancer and nicotine dependence in case-control studies with high smoking exposure; however, its influence on lung function and COPD severity in the general population is largely unknown. We genotyped 57,657 adult individuals from the Copenhagen General Population Study, of whom 34,592 were ever-smokers. Information on spirometry, hospital admissions, smoking behaviour and use of nicotinic replacement therapy was recorded. In homozygous (11%), heterozygous (44%) and noncarrier (45%) ever-smokers, forced expiratory volume in 1 s (FEV(1)) was 94.1% predicted, 95.3% pred and 96.5% pred, forced vital capacity (FVC) was 97.1% pred, 97.5% pred and 98.3% pred, and FEV(1)/FVC was 0.770, 0.773 and 0.777, respectively (all p
