Norman Ohler is rather hard on the Nazis, for compared to what our little group got up to in the late 1960s and 1970s, they were shrinking violets in the drugs department. We smoked cannabis, ate opium and sometimes took strong LSD; lines of uncertain content went up nostrils; and we swallowed countless uppers (speed) and downers (tranquillisers, sleepers for looning on).
