Insuffulation
From DMT-Nexus Wiki
Intranasal drug use involves administering the drug via the nose.
DMT must be converted to a salt, usually DMT HCl (hydrochloric) or DMT fumarate (using fumaric acid), before it can be used intranasally.
I.N. DMT use is considered longer lasting than vaporized but not as intense, and harder to break through.
