People who smoke are 33% more likely to develop asthma than those who do not, researchers from the Finnish Institute of Occupational Health have said.
Smoking has long been thought to aggravate the condition but whether it caused it has been disputed.
The study also found that female smokers seem to be at a greater risk of developing asthma than their male counterparts.
