Just to get this back on track, the health of your nose would be best served by making nasal solutions that you spray or snort a few droplets of in order to dose. This primarily prevents the air from carrying the powder into your upper lungs, which, while not a part of the nose, is still certainly relevant. Snorting anything with talc is a very bad idea, as it gets into the upper lungs and cause talcosis (again, the lungs are actually where a lot of concern should be over the health of snorting things)...
Another positive to making a solution is that you can use saline as a vehicle for delivery, and this should reduce irritation to the mucous membranes. If you put a lot of irritable material in your nasal cavity, saline won't prevent the material from damaging the membranes, so be wary of this as well.
In summary, snorting safely should follow a few basic steps: 1) Make sure there is no ingredient in the pill that makes it unfit for snorting (talc being the primary offender, but there are others); 2) Make sure the chemical itself isn't obviously damaging or irritating to the nasal membranes, such as 2C-T-7, methylone, etc... (If you decide to snort these, know that they aren't safe or pleasant to snort...); 3) Make a solution, either a large, multi-use one, or just put a few drops of saline over your line or pile of powder (put in a spoon or measuring cup, and use just enough saline/ liquid to absorb it fully), and then snort it/ spray it up there!
