was listening to his hamster regarding this topic the other night. Mr Hamster likes to ramble on about all sorts of things he gets excited about.
First, from a harm reduction
point of view, Mr Hamster agrees with some of the other posters here and never shares straws, bills, or other implements which might me in contact with or even puncture the thin mucus membranes in his nose. This is a prime route for the transmission of the common cold virus, to more nasty things like Hep C. and possibly even AIDS, though he feels the latter is an outside chain, but still doesn't want to risk it. Besides, he thinks it's kind of gross to put something up his nose that some other, possibly very cute hamster, has had up her nose. After all you wouldn't want to blow your nose with someone else's handkerchief or vice-versa, just not a pleasant thought.
Secondly, Mr Hamster, again thinking of harm reduction likes to get the implement up inside past the thinest part of his nasal septum. His theory is that any direct contact with this thin part of the septum is causing additional insult and injury beyond just what material from his hamster treats might be contained mucosa flowing down from the inner sinus cavities to the nasal opening.
Another very important point Mr Hamster follows almost to the point of being anal retentive, is to make sure his hamster treats are ground into as fine a powder as possible, almost to a fine dust. This helps with absorption and he finds he is satisfied being able to use less because less is wasted. Also, since it is a very fine powder, he only needs to cover one nostril and inhale normally through the other where he has his favorite or handy implement. This dose two things, it keeps the noise down because he is inhaling as he would normally, and it also lets the dust (again ground as finely as possible) accumulate in the sinus cavities rather than hit the back of his throat or continue on into his lungs.
SWIM thinks his hamster friend obsesses over things like this a bit too much, but also thinks that Mr Hamster may have some valid points. Mr Hamster is just trying to be thoughtful by passing this along and hopes it's helpful.

SWIM forgot to mention one more thing his hamster told him, is that one should be careful and not shove too hard, and try to avoid puncturing the walls of the mucous membrane because they are fragile. Further, this may be difficult to determine since what's being inhaled is also a powerful local anesthetic. Nosebleeds are never any fun under any circumstances.
