As far as total displacement is concerned, presumably as the plants interbreed among themselves, the recombinant genes will be passed on.
I thought your argument was that the recombinant strains of mj would be useless for getting a THC high from smoking, thus rendering the smoking of mj useless. If so, then a low THC strain should accomplish the same thing.

So why haven't ditch weed or low-THC hemp plants done the same? And what is to stop growers from selecting out seeds from recombinant plants, or breeding out such a trait?
