Methamphetamine is good for two reasons:

1. At a therapeutic dose methamphetamine, aka Desoxyn, is less neurotoxic than other stimulant medications which are used to treat ADHD (and potentially other conditions but that's more speculative and off the beaten path for psychiatry) and this is important because it provides a much-needed alternative for situations where the more conventional stimulant meds are not tolerated or ineffective for any number of reasons. Honestly if it weren't for the stigma there's a good chance that on the basis of risk of harm to the patient and effectiveness, Desoxyn would be given preference over Adderall and lisdexamphetamine.

2. The discovery of methamphetamine and the widespread usage of it, aka Pervitin, critically undermined the Nazi war effort because they were able to utilise it to achieve early gains and it allowed for pushing Nazi soldiers to run on virtually no food, both of which looked good on paper especially in the early stages of the war but it was entirely unsustainable and so it made the top brass of the Nazi armed forces completely overestimate their abilities, thus leading them to overextend themselves and especially to overextend their soliders which led to a paper tiger effect where the Nazis appeared to be much more threatening but, when facing stiff resistance, they tended to crumble.

Hate Nazis? Support neurodivergent folks?

Love meth!
