Many times when a doctor learns you have ADHD and especially if you take meds for it they'll just treat you like a drug addict. You have to go through massive hoops to refill your meds every month and even if you've been taking the same exact meds for over a decade, doctors will still treat you like filling the prescription is a massive risk and think getting ADHD meds is "drug-seeking behaviour". Often, doctors have many biases against mental disorders, and ADHD is one of the clearest to see. Outside of the US/Canada many ADHD meds (even non-stimulants) are just outright illegal too, but that's slowly changing.

There's also the problem of insurance. Insurance just goes out of their way to fight you over ADHD treatment costs, especially meds. They deem it "non-essential" and even if you get them to cover a prescription once, you'll probably have to deal with them denying it again. It actually causes people to not be able to take the only medication that actually helps them (different meds have different effects on different people, and some medications can cause things like pretty bad headaches or lack of appetite which are unpleasant, or just flat out don't have an effect.

The ironic thing is that most of the problems you have to deal with to get ADHD meds are also things that ADHD literally causes you to have an extremely hard time doing. It's a sick and twisted joke lol.

Thankfully, I haven't experienced the part about doctors myself, but I'm very close to people who have and it's super common to find people venting about it on ADHD communities.

But I think the takeaway is that neurotypicals abusing the substance has made big problems for people who actually use the meds for the disorder. Of course, drug abuse shouldn't make one group able to "take away" the right to meds from another group, and people should be allowed to use drugs recreationally, so in reality the laws are the problem.
