This was always going to happen. It was only banned in the first place to clear the field of foreign companies that dominated the market. So now - 6 years later - american companies have finally caught up, it's time to repeal the ban.

Side note: I don't necessarily think this is a bad thing. I mean if someone's going to profit off the misery and suffering of addicts, it might as well be their fellow countrymen.

EDIT: re:"it was only banned" : I know it was technically illegal, however I suspect that wouldn't have been an issue if it was a field dominated by american companies.
