If you are buying grey, I don't imagine there will be any issues at all. They can't stop illegal drugs, they can't stop steroids, they can't stop bootleg meds, they really can't stop anything from coming into the country. The US based companies might have some issues which may drive more people to the grey market. But I think Karen the soccer mom will have a hard time accepting and/or navigating the sketchy nature of buying grey. So I don't think the influx of people making the switch will be enough to affect the supply/demand. This is all just my speculation of course.
