Most international pharmaceutical companies have some presence in the US, so the US quota has a world-wide effect.
Additionally, prescriptions are for very specific doses of specific variants of the meds. Because it's a controlled substance, pharmacies aren't allowed to use any substitutes (not even something common-sense like dispensing 2x30mg for a 60mg prescription). This makes shortages happen even before all of the quota runs out, because some commonly used doses run out sooner.
Are they doing anything about that? Seems like a very tractable problem.
It does sound like the quota-setting system was designed for an era where the “legitimate” growth wasn’t on the order of “10% a year for 15 years”:

Instead of hoping for a Trump EO to nuke the DEA (literally or figuratively), why not redistribute Controlled Substance Act enforcement? Agencies like the FBI or HHS already handle overlapping domains. The DEA's rigid gatekeeping, especially on research and quotas, stifles innovation more than it curbs abuse.
What's also common is ADHD in adults being self-medicated with things like caffeine and nicotine. I'm not saying that this will help their kid, but clearly we're ok with some things that are medicinal being uncontrolled.
The real issue with increasing legal access to speed is that you're never fully aware of the impairment that amphetamines cause, because they make the user feel cognitively-enhanced, regardless of reality. In contrast, with alcohol and cannabis, the user is generally well-aware that they are not safe to drive or operate heavy machinery.
I have known SO many people on prescribed amphetamines who either wrecked their cars or narrowly avoided doing so. When I was on it, I narrowly avoided rear-ending multiple different cars before it finally occurred to me that I probably shouldn't be driving. Until that happened, I felt like my driving was being made better by the amphetamine, and for repetitive aspects of driving it probably was. For reaction time and spatial awareness, amphetamine was impairing.
Think of the profound-seeming drivel-filled essay written by a college student cranking out an essay last-minute while high on Adderall and now imagine these people all over the place, driving large pickup trucks with similar misplaced confidence in their cognitive abilities.
