A video has gone viral on Facebook showing cancerous lungs versus healthy lungs. A nurse from North Carolina has shared that the black lungs were from 1 pack of cigarettes a day for 20 years.
The video is pretty disturbing and shows why smoking is so bad.

In the video, two real pairs of human lungs are laying side by side. The ones on the right are healthy and pink, while the ones on the left belonged to someone who smoked a pack a day for 20 years. The habit left their lungs black, wrinkled, cancerous, and damaged due to chronic obstructive pulmonary disease, a lung condition that includes chronic bronchitis and emphysema.
You see a nurse inflating the different lungs and the result is crazy. The black lungs can't hold air as long as the healthy lungs can.
