A roach is the end of a joint and is often too small to be smoked for fear of burning ones fingers. As a result, a roach is typically smoked with a roach clip or saved with other roaches to be used in another, stronger joint or added to a bowl. A roach is brown in color because of it high resin consistency due to smoke deposits settling each time it’s inhaled.
“Dude, grab those roaches. Haven’t been to the shop to re-up yet.”
