Stimulants Adderall bioavailabilities

[mtu mwendawazimu]

Hello,

I read online that Adderall has a higher bioavailability insufflated than oral. How is that possible if it's meant to be taken orally?

I know, for example, meth and cokes bioavailabilities are around 75% insufflated, which is the same bioavailability for Adderall taken orally.

If it's true that insufflation is higher than oral, it must be by a small amount, right?

I doubt it. However it could seem more bioavailable due to how rapidly it reaches the brain. If your not using tools to measure it you might be more likely to over estimate something that happens rapidly and underestimate something that happens slowly.
