This was an interesting look at the use - and abuse - of drugs in Nazi Germany. Especially striking was the contrast between the clampdown on recreational drug use during the early days of the Reich and the routine use of amphetamines in the military to keep the troops going with very little rest. Hitler's increasing dependence on a cocktail of dubious drugs - and his equally dubious physician - was also a revelation. This was  a bit slow and repetitive in places, but overall a good read.
