why do you need roach for a joint
Roach (smoking) In Europe, the United Kingdom and most Commonwealth nations, the term is often used more specifically to refer to a short tube, commonly torn from a pack of rolling papers, that may be present in the unlit end of a joint.[citation needed] This hollow mouthpiece, customarily made of thin cardboard, is termed a filter in North America. In other parts of the world other materials are also used, e.g. steel. The steel roach was invented to fill the gap of reusable product category and it also does not have as much crystal deposits like paper filters. It is commonly set in position during the rolling process, or may be inserted later. When the use of a roach is employed, a joint can still be held securely after it has burnt down to a short length; thus, the entire length of the joint may be smoked, without the aid of a roach clip.[1]
Brown marmorated stink bug The odor from the stink bug is due to trans-2-decenal and trans-2-Octenal.[13] The smell has been characterized as a "pungent odor that smells like coriander."[5] The stink bug's ability to emit an odor through holes in its abdomen is a defense mechanism meant to prevent it from being eaten by birds and lizards. However, simply handling the bug, injuring it, or attempting to move it can trigger it to release the odor.
