Combusted cannabis doesn’t have the cancer outcomes associated with combusting with nicotine. Same for second hand smoke.

Cannabis is not laced with perfumes and additives as a rule, as commercial cigarettes are. Cannabis has properties that pair well with physical and cardiovascular activity, unlike cigarettes, even when smoked.

Cannabis habits in youth are also displacing booze and associated lifestyle risks and lifelong impacts (early and unplanned kids from intoxicated hookups, drunk driving, among others).

There is a spectrum of outcomes, moving towards outcomes that are less harmful and provocative of third parties symptoms is better for everyone involved (hospitals & taxpayers too). That’s about being more informed and empowered not smarter. Perfect is nigh impossible, harm mitigation and outcome maximization is what we’re doing, refining the window over time.

It’s a little bit smarter because cannabis smoke airs out in a relatively short period of time, compared to tar from cigarette smoke permanently ruining basically everything it touches.

If cannabis smoking also offsets alcohol or other drug use, that seems like a win. I have never seen a person get violent after smoking cannabis, much the opposite.
