afterburner

Marijuana, usually in the form of a joint, that is smoked towards the end of a DXM trip which synergizes with and enhances the remainder of the trip (akin to a jet engine igniting its exhaust fumes mixed with fuel to generate an afterburn)

The 2 psychonauts each had an afterburner as their robotrip began to wind down.
