This does not fall under "intelligent discussion of cannabis use" because, there's no harm reduction value in trying to um, smoke marijuana through your nose. The smoke is absorbed by your lungs and that's why you get high, and if you hold it in long enough there is no smoke visible of the exhale. Smoking something through your nose I've heard is very painful, and more of a novelty thing, but I'm confident enough to say it doesn't make you any "higher" since the cannabis is still be absorbed through your lungs. It's sorta like coughing, some argue it makes you higher, some argue it doesn't...but in this case, no, it would just be painful. Closed.
