Adolf Eichmann’s last meal was half a bottle of dry red wine (Carmel, an Israeli variety). I suppose today alcohol might interfere with the euthanasia drug being used.
Why do we use those complex drug mixtures? It's absolute stupidity.
Put them in an old-fashioned gas chamber, and purge it with 100% dry nitrogen. It's guaranteed fatal, quickly, and nontoxic when the chamber is flooded with room air after the condemned is dead.
