Blitzed offers a new perspective on the history of Nazi Germany, exploring how widespread drug addiction influenced one of the world's cruelest regimes — and one of history's most infamous dictators.

The rise of Nazism is one of the most discussed periods in history.

For decades, historians and political theorists have attempted to understand the factors that contributed to this infamous political group.

The relationship between the Nazi party and psychoactive drugs is not one that is often discussed — but it is a key point of their history.

Norman Ohler is a German bestselling author and novelist. Blitzed is his first non-fiction book.

After being told offhandedly by a friend that the Nazis 'took loads of drugs,' Ohler combed through the German federal archives in order to compile an alternative perspective on the party's disturbing history.
