What is a roach weed?

Roach weed, also known as roach material, refers to the leftovers of a marijuana joint or cigarette. When smoking a joint, the roach is the small piece of paper or cardboard filter at the end that is left behind when the joint has been smoked down to a short stub. Roach material may also contain small fragments of cannabis flower that were too small to be smoked in the joint.

Some people choose to save roach weed to use later in a homemade pipe or bong, while others may discard it. The potency of roach weed can vary depending on how much of the joint was smoked before it became a roach, so it's important to be cautious when using it.

Roach weed is not as potent or desirable as fresh cannabis flower, but it can still be used to create a milder high or extend the life of your cannabis supply. It is not uncommon for users to mix roach weed with fresh cannabis flower to create a custom blend.
