Help Lately I've been thinking about using H2S

[sla_porra22]

Lately I've been thinking a lot about using h2s as a method. I've done some superficial research so far, but it seems relatively quick and "easy". The materials are easy to obtain too. My only concern is accidentally poisoning someone, but I believe I can handle that. Has anyone tried using this method? How did it go? What products and in what quantities did you use? Why did it fail?

I'm not sure, but I think I heard someone say that this was a non-method, but I'm not sure why, nor if I actually saw it or just dreamed it
