Check out /u/commiespaceinvader's answer in this thread: There is a thread on r/books about "High Hitler", a book about Hitler's drug use. Is this book considered to be accurate?. It's actually the third time CommieSpaceInvader has written about the book; he links to the both the earlier threads as well if you want even more details on the book.

Across the three answers, he goes into quite a bit of detail about the problems with the thesis (as well as a discussion of methamphetamine use in the Third Reich, which was particularly widespread in the army), but the simplest summary is probably from his first lines of the above linked answer:

Ohler's book suffers from a problem that both academic and pop history tend to both have if they are done shoddly: The superelevation of one aspect of history, which results in an almost mono-causal explanation. From Hitler's decisions concerning the persecution of Jews to the fall of France after 6 weeks in 1940, according to Ohler this all comes down to Pervitin. And that's a problem.

While you wait for new answers, you will almost certainly be interested in these answers by the formidable /u/commiespaceinvader here , here and here .

These are three threads posted regarding the book and drug use in Nazi Germany in general.

And of course the Richard Evans review is available on the Guardian website here.

Happy reading!

A further question (although I don't know whether it would be more suited as a submission in itself): is much known with certainty about Adolf Hitler's drug habits (or health) during the latter stages of the war? There has been much speculation in a recent thread that shows a gif of Hitler rocking back and forth during a public event.

The Dutch translation of the book 'Drugs en het Derde Rijk', contains a small extra chapter on the role of amphetamines in Dutch society in the same time period. It sort of deflates the 'uniqueness' of the amphetamine use by the Nazi's.

The Dutch addition was written by the historian S. Snelders. He also spoke in a Dutch radio program about the book which I could link if anyone is interested (The spoken language is Dutch). There Snelders also makes the point that 35 million pervitin pills are actually not that much if you have to distribute them over million of soldiers.
