Shocking footage shows the tar-blackened lungs of a chain smoker who was hooked to the killer habit for 30 years.
Instead of being a healthy pink, they were charcoal in colour and extremely inflamed from decades of tobacco residue clogging them up.
Doctors from the Wuxi People’s Hospital in Jiangsu, China, extracted the organs after the 52-year-old man, who had multiple lung diseases, died.
The video, recorded by the surgeons, has been viewed more than 25million times on social media, with users dubbing it the ‘best anti-smoking ad ever’.
It was uploaded by the hospital with the caption: ‘Do you still have the courage to smoke?’
The patient had signed up to donate his organs after death, but medics quickly realised they would not be able to use them.
Dr Chen, a lung transplant surgeon and also vice president of the facility, led the operation.
He said: ‘The patient didn’t undergo a CT scan before his death. He was declared brain dead, and his lungs were donated shortly after that.
‘Initial oxygenation index tests were okay, but when we harvested the organs, we realised we wouldn’t be able to use them.
‘We Chinese love smoking. It would be impractical to say that we wouldn’t accept the lungs of all smokers, but there are strict standards.
‘[We would accept] lungs from people under 60 years of age who have only recently died, minor infections in the lungs and relatively clean X-rays are also acceptable. If the above conditions are met, we would consider transplanting the lungs.’
