The new guidelines could make it tough for death penalty states, like Texas, that have been looking at made-to-order execution drugs from compounding pharmacies as the answer to a nationwide shortage of execution drugs. Prison departments have had to buy made-to-order execution drugs from compounding pharmacies in recent years because the pharmaceutical companies they used to buy their drugs from now refuse to sell them for use in lethal injections after coming under pressure from death penalty opponents. Tennessee has approved the use of the electric chair if lethal-injection drugs aren't available, while Utah has reinstated the firing squad as a backup method if it can't obtain the drugs.
