Snorting and pupil dilation

[AdderallJunkie102]

Swim finds that when he snorts his Adderall his Pupils dilate much more then when he swallows it (sometimes Swim's pupils don't dilate at all when he swallows). When Swim snorts his eyes often feel sore or tired much faster then normal and Swim often gets a tension headache that is worse then if Swim had just swallowed it.

Swim's question is why his pupils dilate when he snorts but not so much when he swallows? Swim also wants to know why Swim gets sore eyes faster and get worse tension headaches when Swim snorts?

Any information is greatly appreciated, thanks in advance.
