trip cutter

A substance (typically trazodone) that ends a bad LSD trip early. Trazodone works on receptors that essentially function in a manner opposite to traditional psychedelics, therefore effectively canceling out a trip. It is prescribed for insomnia and panic attacks, causing the user relief from anxiety during a trip and allowing them to calm down and "sleep off" the bad trip.

I'm having the worst fucking trip right now bro, do you have any trip cutters on hand?
