I've had them twice in just over two years on the line, so in my relatively brief time I agree with it being rare. It is rather irritating, but as was stated, really like having to hang out in a smoke-filled bar. Or for that matter, any pub or bar in much of Europe, though lately that is changing even there.
If worst comes to worst you could put on the mask. And below 10 the safety signs are on and they need to put it out in preparation for landing.
If they were chain smokers and there's another pax leg scheduled out of the destination, personally I'd send an AFIS message to the company that they really need to get another plane to recover the flight because nothing short of professional cleaning is going to expel the odor.
