A filter – also called crutch or tip – is a mouthpiece that aids in holding the joint. If you’re used to rolling spliffs without a filter, you should give it a try to make your smoking experience more enjoyable.
We bet this is your favorite benefit. If you don’t put a filter in, you’re left with a roach you have to deal with or you might burn your lips as you puff your way down to the roach.
Making a crutch provides a better and more consistent airflow through your joint. When rolled perfectly, it also blocks bits of plant matter from getting in your mouth.
The crutch acts as a solid base when you’re holding or passing it to others. This means it’s less likely to fall apart – no more sloppy joint tips and burnt fingertips!
You can purchase a pre-made joint filter made of glass from your local dispensary. Glass filters need regular cleaning between a joint or two. To remove the residue, use 99% isopropyl alcohol. This will prevent burnt, ashy taste the next time you use it. You can also find wooden filters that you put your rolled joint inside of.
Aside from reusable glass tips, you can prepare your own crutch using a blank index card. Learn how to make a filter tip in this video.
