Filter tips make a joint smoother, cleaner, and easier to smoke: they cool the smoke, catch loose flower and resin before it reaches your mouth, and give the paper a firm cylinder that burns evenly from light to roach. A tip also lets you smoke the joint down to the last half inch without burning your fingers or lips. That is why most experienced rollers will not build a joint without one.

What does a filter tip actually do in a joint?

A filter tip, also called a crutch, tip, or roach card, is a small rolled tube of cardstock, glass, or ceramic that sits at the mouth end of the joint. It does not work like a cigarette filter. Instead it acts as a structural core and a coarse screen, shaping airflow and catching debris.

Paper and cardboard tips filter out almost no THC. What they stop is ash, sticky resin, and unburned plant matter that would otherwise pull into your mouth and throat.

Why are filter tips good for rolling joints?

Do filter tips filter out THC?

No, not in any amount you would notice. Cardstock and glass tips have wide openings that pass cannabinoids and terpenes through while catching solid particles. Cotton cigarette filters are a different story: they are built for tobacco, and their dense fibers can trap resin, cannabinoids, and flavor compounds along with tar. Most rolling guides recommend keeping them out of a joint.

Do filter tips make a joint burn better?

Yes. A tip creates a stable airway at the mouth end, which keeps the draw resistance steady and helps the cherry burn in a ring rather than a channel. The rigid tube also prevents the paper from pinching shut as the joint gets shorter, so the last few puffs stay open and smooth.

Which filter tip material should you use?

How do you roll a joint with a filter tip?

  1. Cut or tear a strip of cardstock about a half inch wide and two inches long.
  2. Roll it into a tight spiral or accordion shape that matches the width of your paper.
  3. Place the tip at one end of the paper and sprinkle flower along the rest, slightly fuller in the middle.
  4. Tuck the paper over the flower and roll with your thumbs, keeping pressure even.
  5. Seal the gum line, pack the tip end down gently, and trim any paper overhang.

Common mistakes to avoid

A tip rolled too loosely will slide out or let flower through, so keep the spiral snug. A tip that is too wide makes the joint hard to draw, while one that is too narrow lets the paper collapse. Also leave a small gap between the tip and the flower so airflow stays open.
