In the uk this is well known and its truly heartbreaking really. Most uk hospitals wont put this anywhere else but wards now because of consumption ive heard of mouthwash too
Some in the uk esp the 60's 70's early 80's were solvent abusing Glues, Butane gas etc
I use these gels in hospitals when im there as i dont want to catch any bugs, my mouthwash is alcohol free
Thanks for posting this
