Well, I found it, and it works. This thing kicks out serious amounts of ozone, enough to clean out an entire nightclub full of smoke. The best thing is that it has a variable output control, so you don't have to overdo it, and a timer in case you don't remember to turn it off. You MIGHT have to sneak it in disguised as something else, but I think you could pass it off as a stage light or something. Mount a light bulb on it if you had to. 6000 mg of ozone per hour is no piddling amount, and it weighs only 10 pounds and draws only 1 amp of current. If the smoke is really getting to you, this could help. I have a low smoke tolerance, and that's why I tend to avoid nightclubs. This could keep you from throwing in the towel if you're an affected player. The patented design is very low maintenance, and the ozone elements are cheap to replace, if you ever need to.

This thing can also kill e-coli bacteria in your home in 2 hours or less (but this is WAY above the level needed to clear cigarette smoke odors). So the nightclub is also grungy? Show up early and sterilize it!
Ozone quickly dissipates on its own, and usually breaks down toxins into carbon dioxide, water, and oxygen.
