Can MOT smoke test cause problems?

My venerable (225,000 miles and still going fine) CDT Tourer had its MOT test recently, and passed the smoke test just fine. Driving the car a few days ago, I noticed that it was putting out a fair bit of smoke on acceleration, which is something I hadn't seen before, and I was wondering whether this could be the result of some damage done by an over-exuberant smoke test.

I hope not, of course. It is entirely possible that is has been happening for a while and I just hadn't noticed before, but I don't think so. Anything else I should be looking at for an explanation? It's certainly not down to the mileage per se, as I only do at most 3-4,000 or so miles per year, and it's definitely a recent phenomenon (i.e., it wasn't there when I had 220,000 miles on the clock).
