Method Why isn't hydrogen sulfide method more talked about?

[Syriancel]

I see many people on this site talking about Carbon Monoxide method but not as many people talk about hydrogen sulfide. Is it unreliable? It seems very easy as described in the PPEH.

Been wondering this too, it seems really easy, just has potential to hurt others?

Is it unreliable?

It's one of the strongest and fast-acting poisons. If produced with proper reagents and used for CTB in a sensible manner, reliability is close to 100%. But it maybe somewhat unpleasant to inhale. Carbon monoxide is a less potent poison, but it's completely odorless and non-irritating (when it's not mixed with smelly impurities like fumes of formic acid). There are many ways to make CO at high concentrations, but they're commonly more complicated than making lethal concentrations of H2S.
