Utter foolishness! There are so many more pollutants befouling the air that we should be worried about. Cannabis smoke is nothing if it's not concentrated enough to produce a contact high. The guy using that device reminds of people who go, "hey you smell that? (sniff sniff)," "yeah, that really stinks! (sniff sniff sniff)." And I agree with an earlier comment: if an offending odor cannot be detected without a "nose telescope," then why is it a problem? Especially when it's no more a carcinogen than any other burnt plant matter? Insanity!
