What is a crutch for a joint?

A crutch is another way to say filter tip used for spliffs. A crutch filters smoke for a cleaner experience and prevents burning/staining your fingertips. How to make a crutch for a joint? First, you’ll need to get a piece of paper that’s thicker than printer paper yet thinner than a cereal box, like a manila folder or business card. Cut a strip off, then fold accordion style before wrapping the excess paper around it to form the crutch. If you have a lot of extra paper just remove. Then, simply place it at the end of your rolling papers and roll it up into a joint.
