Insuffulation
From DMT-Nexus Wiki
Insuffulation is a method of administration by intranasal (through the nose) absorption.
DMT must be converted to a salt, usually DMT HCl (hydrochloric) or DMT fumarate (using fumaric acid), before it can be used intranasally.
Intranasally administered DMT is considered longer lasting than vaporized but not as intense, and harder to break through.
