DMT carts are vape cartridges filled with liquid or crystalline DMT, designed for use in vape pens. They heat the compound to vaporize it—no combustion—so you inhale DMT through your lungs for fast onset (within 10–15 seconds), intense visuals and a total trip lasting under 30–60 minutes. Many users appreciate the precise dose control and portability compared to traditional methods. However there’s risk due to unregulated contents health unknowns and legality issues—DMT is mainly illegal.
