I recently watched Toy Story 5 on a long flight. I almost felt it should come with a trigger warning - I thought it was a spot on, brilliant yet inherently depressing commentary on our current relationship with tech.
(Minor spoiler alert) One of my favorite scenes was when a slew of toys were running through a house with a family inside. Normally in the Toy Story world when a human see the toys they need to "play dead", but since all the humans were glued to their screens they could run by unimpeded.
Many medications behave extremely differently under different dosages, delivery methods and variants.
To quote an ex of mine who was a school psychiatrist, "oh, ADHD meds are addictive are they? I wish someone would tell that to my kids who keep on forgetting to take them."
That said, plenty of people with ADHD do actually self-medicate with (black market!) meth and are perfectly functional. To be quite frank, the stigma surrounding meth use is simply harmful in all but the most egregious cases. And even in those cases, usually it's not the meth itself that is the problem, it's simply the favorite substance of the addict (who would've otherwise just gotten addicted to something else instead).
Another often-overlooked aspect is that addicts usually only get addicted to substances because their life already sucks, and taking away the substances without helping their life at all is often just cruel, and especially blaming them for trying to cope with their circumstances. So many members of society use such simple (and flawed) logic, seeing someone using drugs and assuming the drugs are the problem, and that taking it away will make it better. Usually both are false (though some notable exceptions are drugs that form strong dependence like opioids and benzodiazepines, and other drugs that pose a strong risk to life, like research/designer psychedelics -- ones that are not safe like LSD/DMT or psilocybin -- or deliriants)
