Meth is also used as an ADHD treatment. I think the reason is just the dosages that are used by addicts compared to people who just need the ADHD treatment.

A typical legitimate therapeutic methamphetamine dose is around ~20mg (up to maybe 60mg a day). A typical dose used by addicts is around 1 gram. And it's usually smoked, resulting in immediate bioavailability.

I should have clarified that it's a daily dose: https://www.medrxiv.org/content/10.1101/2025.05.09.25327334v...

Not that it matters that much. It's no wonder that it fries your brain when you're using 25 _times_ the normal therapeutic dose.
