the spot most of it lands when you rail it is the nice soft spots up near the top of your sinus. In this area there are a nice little supply of blood vessels right at the the surface to carry all the goodness into your system. Very little actually gets to your lungs - if it did you'd be a coughing shadow of your former self for several minutes (try it with some flour - lungs do not like foreign material).
Other places where there are bloodvessels close to the surface are underneath your tongue (that's why tabs of acid are generally sat there) and your anus (hence the reason why people plug). The next best area is your stomach pretty much.
So if you don't want to rail it those are pretty much the only other spots worth trying. You could try getting it into your lungs but i wouldn't recommend it - even if it is relatively pure meth there will still be some badies, and the body has an awful time trying to get rid of stuff from there. Meth is highly acidic and hardly recommended for your lungs. Speed could be even worse as you never know what it's been cut with.
You could put it under your tongue, it'll taste like crap, will take a long time to absorb and will probably take a year off the life of your teeth each time.. You could shove it up your butt in a quick dissolving cap and this should have the same effect as snorting, albeit it a little delayed.
I'm pretty sure that railing will absorb some 80% of the substance while swallowing it accounts for about 60% (can anyone else confirm/correct this?), so it's all a matter of how much you value your nasal tract, your teeth and your butt...
Good Luck
