‘The Message from the Lungs’ introduced the world’s first ink made from smokers’ lungs. By cooperating with Faculty of Medicine, Chulalongkorn University, we are successfully extracted black substance from smokers’ donated lungs and made it into ink. Then bottled and distributed them in public space for people, especially current and potential smokers to see how smoking can harm their lungs and their bodies, and also convince them to quit sooner.
