Whereas for example, tobacco smoke has been shown to be especially harmful. I think the popularity of smoking tobacco has shaped the views of many as to the nature of smoking anything else. As you say, it's hard to imagine smoking anything is a good idea, but that doesn't mean that it's all COPD, heart attacks, and strokes either. Just anecdotally, people who smoke a lot of cannabis rather than vaping or eating it seem to me, to get a lot more upper respiratory inactions, bronchitis and the like. Will that shave years off your life? Maybe, maybe not, but it's still clearly something to pay attention to, when the alternatives to smoke exist.
