Adolf Hitler's medical care (pdf) features an appendix with a handy (and very long) list of all of his personal physician Theodore Morell's prescriptions with information about present day equivalents. This is based on the information in David Irving's The Secret Diaries of Hitler's Doctor (written before he became a Holocaust denier) but compiled and annotated by an actual physician and therefore lacking the mistakes Irving made due to his lack of pharmaceutical knowledge.

The long list includes both amphetamines and barbiturates. As there is no consistent information on dosages and frequency of use, it is hard to ascertain to what extent these drugs might have influenced Hitler's behaviour. The Medical Casebook of Adolf Hitler: His Illnesses, Doctors, and Drugs by Leonard and Renate Heston makes the case that all Hitler's faulty decision-making is to be attributed to his amphetamine use.

On the other hand, Albert Speer, a very close associate of Hitler, who wrote an introduction to the book, seeems to doubt that, stating "even before Morell began treating him, all his endeavors were from the beginning limitless and irrational. [...] It would be a mistake to try to show Hitler as the unfortunate victim of addiction."
