It doesn't work with MPH... amphetamines only. It's best to be at least in the same family of drugs when talking about interactions like that. I would strongly recommend not switching to adderall to try though.
Any info on that? They're both CNS stimulants, both phenylethylamines, why would THC affect them so differently?
But you're right that the narcissism of small differences is often made manifest in chemistry.
Just wanted to say though, if someone is getting a "high" from Adderall or Ritalin, they're not taking it medicinally, and that's the problem with these discussions, it's very easy to conflate prescribed use with abuse, which ignores the fact that recreational dosages are far higher than medicinal.
