For me the sensitivity to meds is acquired, due to ME/CFS(which seems to be more common among autistic people and people with ADHD).
When I tried "speed" as a teenager, I needed a relatively large amount, but nowadays I only take 5mg of either MPH or Elvanse(currently Elvanse).
My easiest comparison is caffein, which still has the same effect and I just need way less now.
