By insufflating the crushed pills you are still ingesting all those binders and fillers, the only difference being that some of them may go straight to your lungs, whereas by smoking it some of the material may be destroyed and not make it into the inhaled vapor. That being said, I am in no way shape or form advocating smoking oxys, it is probably a waste, and sure as hell can't be good for you, but neither can putting all that powder up your nose. Anyways didn't mean to flame but your avatar is the NA logo and you were advocating snorting pills as opposed to smoking them.
On another note I knew peopl years back(way back.. high school) who thought that you could smoke vicodin, and insisted on putting it on top of bowls, just crushing them up, APAP and all(you can't get much worse than that), needless to say, I abstained and would pack my own bowl, but I did think it was pretty funny(in a sad way).
Anyways, people shoot pills filled with wax straight into their veins, and the residue from choreboy and the shit crack is cut with can't be much better for you. Not trying to justify, rationalize, or advocate smoking pills, just trying to put some perspective on it.

btw. harm reduction is just that, ways to reduce harm, and that is all he was asking, how to reduce harm while ingesting in a different way. A different way to ingest drugs could easily be considered harm reduction if it reduced harm. ie. Harm reduction would be to not call him stupid for smoking pills but to introduce him to a new, less harmful way to do it.
