Well no, there are serious health risk associated with weed. Maybe alcohol have them too, yes both deserve legality, but this is not to say it is "safe", especially in young.
And the last I heard, oxygen was "combustible". Inhaling a combustible isn't a health risk; inhaling combustion products might be. But many pot smokers use a vape, set to well-below the combustion temperature for their chosen herb.
Vapes have issues too, which include exposure to heavy metals. By combustibles I mean anything you burn. Again, not a doctor and not a medical scientist so I may be using the wrong words but most people who use weed know these things. Most notably, anything that is smoked will incur a small but sharp rise in blood pressure. If you wear a heart monitor (or wrist watch with one) it's fairly trivial to detect.
Absolutely, i more made reference to how when somebody mention health impact of weed somebody else say "whatabout alcohol unhealthiness" as though it is relevant.
Of course it is relevant. Many of those 95,000 annual deaths would be preventable if a good variety of quality cannabis was more widely available and its use was more socially acceptable.
I also believe such a paradigm shift would largely eradicate domestic violence.

- the same risk that inhaling any combustible has
- overeating

For some people the benefits outweigh the risks, especially when practiced in moderation.
