The fact that Hitler was a serious addict is true. He was also bipolar, and it is quite likely that the combination has contributed a lot to the beginning of the end of Operation Barbarossa in 1943 (through his faulty decision about not attacking Moscow in 1941, before winter, and before Stalin realized what is really happening). The thing to remember is that amphetamines were way more acceptable in the early 1940s (because the bad side effects were not yet that obvious), for example Wehrmacht soldiers had "superpower chocolate bars" beefed up with amphetamine. They were allowed to consume it in a dire situation. There is a lot of unnecessary buzzing happening in the article though.

I think you're on the right track... From what I've heard as well was that in the later stages of the war, the army largely marched on a stomach full of meth (so to speak). Facts like those could bolster the rumor mill in propping up semi-gossip style information.

I did also have a history professor say that Hitler actually went blind for a couple of days when he heard that the Americans landed on European shores.
