Alright, this is attempt 2 to collect some data on how smoking affects lungs. Last time I was going on force of breath before and after smoking. This time I’m going with length. And I’m finding….nothing. I tested three people, five breaths each before and after, and found nothing. If anything, smoking seemed to raise the average slightly, although this was probably a result of getting to know the test methods better. Either way, I’m willing to say that perhaps there really are no short-term effects of smoking a single cigarette.
