To be clear, when you say doctors endorsed cigarette smoking, a small percentage of doctors were duped into endorsing it and their recommendations boosted by the tobacco industry.
I've got my Grandfather's old copy of The Boy's Companion published before the date in that meme, and it's very clear in its message that smoking is bad for you. They've known it was harmful to health since at least the 17th century, and tobacco was only brought to Europe in the 16th.
The cunts who sent that mascot to the hospital fucking KNEW. (edit: or at least they would have if they existed, it looks like the whole thing might have been AI generated)
It took a sinister turn right at the end...
