Supposedly injections are more humane. Which made it favoured method in America (now when the woke corporations conspire so death rows can't buy anymore poison, they think of bringing back other methods like the electric chairs).
Anyway for example at Auschwitz it was eventually estabilished that the ethnically Polish prisoners who failed medical selections were to be killed via lethal injections (various other methods were used for other purposes, including starvation death in "the bunker", an underground dungeon under the political police building). Many ways were tested, they arrived as at the quickest to inject fenol directly into heart. Families were actually being sent an urn along with a fake death certificate (as just illness).

Of course it would make things much slower.
