What is the purpose of using a roach clip?

The purpose of using a roach clip is primarily to hold the end of a joint. This tool allows users to safely enjoy the last portions of their joint without burning their fingers, especially as the joint burns down. The clip provides a grip that keeps the user's hands away from the heat of the burning tobacco or cannabis material, making the experience more comfortable and practical.

In contrast, measuring cannabis weight, enhancing potency, or storing remnants are not functions of a roach clip. Therefore, it is clear that the primary utility of this tool revolves around its design to assist in holding a joint, making it an essential accessory for users who wish to maximize their experience while avoiding discomfort.
