Not really typical of cigarette smoke, IMO.
And neither is it typical of light leak (film camera). See examples
Whatever it is, it seems to be in front of the lens and not mingling with the people. I say that because I don't really see any of the misty mixture weaving in and out of the crowd.
Whatever it is, cool capture.
There is one that anywhereBright Light Leak with Lens Refraction or something similar that looked very similar to the photo with the group of people in it, but for the most part the light leak photos didn't resemble the photos, just that one did.
I have tried to duplicate results that my friends and I have gotten while taking photos and both of these photos do look very much like smoke. Not necessarily cigarette smoke, but if you are trying to duplicate results then using a cigarette to produce smoke is probably the easiest and quickest way to do it.
If you exhale the smoke with force, you'll get a lot of straight streaks and not a whole lot of the curling effect. If, however, you just let the smoke kind of rise up from the cigarette on its own and be carried by whatever ambient breezes are around, these photos are pretty much what you get. Now mind you, this same effect can be gotten with smoke from a barbecue grill as well.
I don't like the word suspicious because it conjures up images of trying to put one over on somebody, which I am certain was NOT the OP's intent, but it's the only word that I can think of to use. So what makes me, for want of a nicer word, suspicious of the anomalies in these photos is that in both of them, the anomaly originates outside the screen, so it could have come from anywhere. A fireplace. A barbecue grill. The OP states that nobody in the photo was a smoker, but what about someone NOT in the photo? If the weather is damp and chilly it could be exhaust from a just-started car. If the anomaly was confined within the field of view then it would leave much less room for doubt. But coming from off-screen it could originate anywhere which makes it very difficult to guess what it could be. Interesting photos in any case.
