Attempting to understand those between the lines meanings of this subject question fashions dilemmas anew.
Music (hearing & vibration), smoke (taste & aroma), food & drink (taste, aroma & texture) among other such pleasure sense things are endemic to the human condition.
Aroma, be it a new mown field, fall leaves burning, a parlour fireplace, a charcoal grill, a horse barn, a good cigar or favorite cigarette blend, all are pleasures even beyond that of taste. If the cretins don't get it, so be it, research or clam up
Music without an accompanying aroma of good Turkish, Virginia, Cuban or other leaf does to me seem quite uncultivated. We're on the Moon, wake up! To ban "smoking" from odd off chosen places as this thread suggests would as such open risk of lingering truly dark ages obnoxious odors, to mention just two, methane and the perfume of the overweight. I see here no contest of comparison. When in an eatery, were I to observe an obese at an adjoining table consuming Brussel sprouts and corn, I would myself quickly request quietly of the management to be reseated at some greater distance, thus at the completion of my meal I would also expect to enjoy a smoke of my choosing in serenity.
Would I, could I, request banishment of the overweight from the pain to my eyes, (you must know they are being taxed now in thoughtful places) me thinks a more substantial subject discussion (non music threads) than a ban on smoking in pleasure palaces.
Smoking in itself, is not just a simple thoughtless multiple pleasure for the user, it is also a defense from those unconscious that permeate the aroma of surround.
Having rolled my own choice of learned gourmet leaf beginning circa 1945 to the tune of 40 to sixty per day, have become somewhat of a connoisseur as a result. Likewise of coffee if one would allow the comparison.
I play and sing a gig most every night. To tune my voice I smoke very heavily before performing otherwise I would sound like Kendall (remember how great he sang back in the old days when he smoked?:)... so thus would never consider contracting with a venue of non discerning no smoke cretins.
I also stand on the premise if you care to know, as Savarin suggests, in hunger being the best sauce. Listen to your body, "You are what you eat"/smoke/drink!
In closing this offering of just another opinion, I would like to suggest the possibility that if "folk clubs" for lack of a better term, continue to impose smoking bans, a more eclectic music might take its place and with the discerning, smoke will return.
Can we expect next that Starbucks and the other high end sugar & caffeinee shoppees will outlaw their health risk poisons? Nope I don't think so!
Can you picture the old fiddlers who kept the tunes alive for centuries until tech allowed us to record... without their clay pipes? I can not! LOL   Mountain Tyme
