Is There Any Difference Between Swalloqing and Snorting Pseudoephedrine?

[ChemicallyEnhanced]

I started taking 120mg of Pseudoephedrine three times a day several months ago for appetite suppression and energy (and lack of current access to anything stronger). I now take 240mg 3-4 times a day.
Would switching to snorting it up the effects or amount absorbed so that it would reduce the amount it need?
I'm thinking snorting maybe wouldn't work, but I can't find a real answer anywhere.

I doubt it Wikipedia lists bioavailability orally as near 100% which im inclined to believe as amphetamine is structurally similar and also 75-100%.
