This is what cigarettes really do to your lungs

Good morning, this is gross. 

You’re looking at the expansion and contraction of two lungs—one of which came into first-degree contact with cigarettes, the other of which didn’t. 

We’ll give you five minutes to guess which one’s which.

These types of comparisons have been flooding anti-smoking campaigns for years; just type “smoker’s lung” into Google to get a good read on how vast the effort’s become. Something about the robustness of the good lung’s expansion juxtaposed against the undeniable struggle going on with that smoked-out lung really hammers the point home. 

Here’s hoping you didn’t open this story during your smoke break.
