yes, if you feel you dont have enough for ingesting orally you can do that. if you have enough, might as well dose it straight. but im sure it is safe to snort.
The amount required for a euphoric dose would require insufflating a ton of material. There are binders and inactive ingredients to worry about as well.
It depends what type of DHC you're working with (pills/pure powder).
If it's powder go ahead and find out for yourself, if it's pills just do a CWE and take them orally, far too much powder to sniff.
