Oh yeah smoke is obviously damaging but there's many other ways to consume weed in ways that invoke no smoke. Edibles, vapor, oils, and a couple way I can't think of. And I have to disagree with you saying we shouldn't do any of these substances. Everyone needs a vacation for reality at some point in their lives. A little 2 hour break with friends every couple weeks is fine in my eyes. Moderation is really the key to any substance.
