The SS incident was mentioned in the history channel show about German drug use.
There is a book called Blitzed: Drugs in the Third Reich by Norman Ohler. It was first published in German in 2015 and the English translation in 2017.
I plan to get it at some point. Using the Amazon viewer, the bibliography is primarily German sources.
Excerpt from the Amazon site:
Drugs seeped all the way up to the Nazi high command and, especially, to Hitler himself. Over the course of the war, Hitler became increasingly dependent on injections of a cocktail of drugs—including a form of heroin—administered by his personal doctor.
There is also a PBS documentary on Allied use:
Secrets of the Dead: World War Speed - June 25. 2019
When American soldiers landed in North Africa in 1942, they were also operating under the influence of speed; half a million Benzedrine tablets were supplied on the orders of Gen. Dwight D. Eisenhower, according to PBS. Also featured in the PBS documentary is a 1942 memo from a British commanding officer, stating that British 24th Armored Tank Brigade soldiers received 20 milligrams of Benzedrine per day, prior to a battle in Egypt. By comparison, the recommended dosage for pilots in the Royal Air Force at the time was only 10 milligrams.
