There’s a lot of research disagreeing
The reality is no, cannabis probably doesn’t block carcinogens. Nor is it more harmful to your lungs than tobacco. But it’s not really clear that it’s less harmful than a filtered cigarette. I think it is probably a bit healthier of a habit just in that people usually smoke much lower quantities. But if you take a smoker and stoner each smoking 10 times a day they’re both at a higher risk of lung complications than non-smokers. Also importantly, cannabis is not chemically addictive (it definitely can be an addiction though) whereas nicotine very much so is.
It’s also just not at all the same thing.
An aircraft mechanic can’t just go out on his five minute break and smoke a j and go back to it.
Yeah, maybe one small hit at best. Who’s smoking 10 joints in a day, wtf?
