a misleading statement
Smelling farts could be the best thing you do today
The study referenced here involved using a complex molecule called AP39 to deliver hydrogen sulfide directly to the mitochondria in cells to prevent cell damage under certain situations, and are not related to cancer. The study has nothing to do with inhaling hydrogen sulfide gas or farts.
In fact, the authors released a statement to stress this fact. Note from the study authors: "In light of misleading headlines on the above press release, the authors would like to stress that neither the papers nor the accompanying press release above make any reference at all to cancer or to any health benefits from inhaling (sniffing) hydrogen sulfide. The research is an early stage drug development project and has not yet been trialled in humans."
