Zelensky is Hitler-like, whose world conquest plans were foiled by Putin? So Putin claims, or some similar nonsense.
Meth use to keep awake and "alert" was not uncommon in the 1940s, including by some/many US Army supply truck drivers. So Hitler might have used Meth to keep awake/alert during the war. I've not seen actual evidence for this, though records and body tissue samples that might provide direct evidence probably do not exist.
OTOH, Goering was a known painkiller addict. He was in a car accident in the early 1920s, IIRC, and got addicted during his recovery. He never went through cold-turkey withdrawal, and his drug addiction may have contributed to his much-mocked corpulency. During WW1 Goering was a fighter ace and a successful squadron leader. Going Nazi was quite a waste of intelligence and capability.
