Roach Definition
Roach is the name given to the end of a marijuana joint. Just like a tobacco cigarette has a tip, a weed joint has a roach that is often left unused because it is too short to be held. It is brown in colour because every time a user inhales through a joint, resin remnants collect at the tip. A clip is often used to smoke a roach, or multiple roaches are collected in a bowl to be used at some other time.
