I use regular saline nasal spray. Do not use any of the mediated nose sprays they work by constricting the blood vessels in you nose and sinuses which causes anything you snort after to not be absorbed properly. When snorting pills, I will also use a q-tip to clean inside my nostrils/sinuses. What I do is wet one side of a q tip and then clean out my nose as if it were my ears. If you tend to snort a lot of pills you will be surprised as top how much colored gunk gets stuck up there even after you blow your nose.
