I'm fairly sure the actual poisonous agent is cyanide in the normal method in the US, but not clear on how they produced it.
I'm vehemently opposed to the death penalty of any kind but I think it's worth pointing out that pro death penalty groups have argued for the use of nitrogen asphyxiation as the ideal execution method. You basically fall asleep with no sensation of struggling for breath or pain before you die. Cheap and considerably less agonising than cyanide. Choosing cyanide is basically torture and execution.
