It's so weird to me that people use Adderall recreationally. It's as "recreational" in my mind as functional shoes are. I usually need them, but they're usually not what makes an activity fun.

How is crushing up Adderall and snorting it even worth doing?

I've accidentally taken my "normal" Adderall twice and it's an extremely uncomfortable experience. The last place I'd want to be in that state would be at a party, getting drunk. Sitting in a quiet place and rocking/sweating/puking until it's done is more what comes to mind.

For what it's worth, there's no "quick release" Adderall. There's a normal kind, and an "extended release" kind (officially Adderall XR). The latter encapsulates little beads of the drug in coatings that dissolve at different rates, allowing the dose to be spread out over a longer period of time. What I think you're referring to when you say "quick release" is the non-XR variant of the drug.

The drug found in Adderall XR is identical to that of Adderall with the exception of the coatings on the beads. I think crushing up those beads would likely work the same as crushing up an Adderall tablet, assuming the coatings on the beads were also suitably crushed. Not something I'll be testing any time soon though.
