    Dear editor,

    We read with great interest the article by Kentaro Watai et al. They describe Short-term active smoking in early adulthood may be associated with decreased lung function and AHR, even in patients with intermittent adult-onset asthma. However we would like to make one comment.

    There was a period from the first visits to a histamine airway challenge test. If never smokers were receiving treatment by the time of the test, ther AHR would be lower than expected.[1]This information bias will weaken their conclusion.
