The problem States are having is that companies refuse to sell the drugs to the States because of sanctions imposed on them by the EU.
Oh come on now. That isn't even bullshit. It is horse shit.
The drug companies that produce the drugs used for execution realized that their drugs, which were originally designed to save lives, was being used to take lives. Every statement made by those companies state that. In other words, they made a moral judgement that they didn't want to be seen as providing death on one hand and life on the other. Sure, the EU pharmacies were the first to refuse but your statement doesn't take into account the American companies refusals.
