Right you are! Inhaling any type of particular matter, which is what smoke is made of, is hazardous to your lungs. Why do states legalize smoking weed but not cigarettes? It is completely psychotic behavior!
As a bit of perspective I grew-up in Pittsburgh where environmentalists decided to put 80,000 men out of work rather than have us continue to breathe in smoke that was at 1/100000000 the level you’d get from smoking any of this stuff.
