How to make a joint filter

Whether you are new to smoking marijuana through joints or have been rolling for years, learning how to make a joint filter is an excellent skill to have. Though technically, you do not need to use one to enjoy the benefits of smoking, the addition can add a variety of benefits that will have you hooked in no time. Here we will cover how to make a joint filter, the benefits of using one, how to use one, and a few premade joint filter options for those that are still struggling to learn.

Benefits of using a joint filter

Though there are many more benefits that can be achieved depending on the materials that are chosen to make a joint filter, these are the four main reasons that most cannabis enthusiasts prefer to use them.

Keep cannabis grind from entering your mouth.
Though marijuana edibles are one of the hottest products going, there is absolutely no reason to eat cannabis. A lot of people think that if you eat a freshly cured bud, it will get you high, but the THC in the plant materials needs to be activated through heat before it produces the psychoactive benefits. I good joint filter will keep your bud grind where it belongs, inside of your roll.

Prevent resins from blocking the airflow through a joint.
If there is one thing that cannabis is known for, it’s the sheer amount of resins that are present. As you smoke a joint, much of this sticky substance will build up at the opening, which can eventually make it difficult to take a hit. A joint filter will keep the walls of the mouth portion open, which helps the air and smoke to travel freely.

Easier to pass.
A joint filter provides something solid to hold onto, especially once the roll burns down to a small piece. Since the marijuana grind doesn’t reach the tip of the mouthpiece with a joint filter, the heat also stays back from the fingers.

Less waste.
Joint filters often take up to 20% of the roll, and the longer they are, the further away from your fingers it will need to burn. Once you puff your way to the filter, all the delicious buds will be gone, so you don’t have to worry about collecting stinky roaches or throwing away perfectly good product.

How to Make a Filter (Crutch) and Roll a Filtered Cannabis Joint

Thursday November 21, 2019

W hether home growing your own cannabis flower or picking up some tasty nugs from a dispensary, there’s something about the process of rolling and smoking a cannabis joint that makes the experience so much more rewarding. Though we’ve discussed the basic procedure for rolling a joint in the past, today we want to discuss another element of the whole doobie-rolling process: rolling a filtered joint.

Why Use a Filter in a Joint?

A filter, or crutch, is a great way to improve the joint smoking experience by improving airflow, maintaining the integrity of a joint, and blocking little bits of weed from hitting the back of the throat upon inhale. Additionally, many joint-rolling experts use filters as a form of creative expression, for example, by shaping them into a pot leaf or other 420-friendly symbol.

How to Roll a Filtered Joint

Filters are the stiff cardboard-like paper on the mouth end of most dispensary joints. Though most dispensaries use pre-formed “cones” in which to stuff ground cannabis, you can roll something similar using regular rolling papers and a crutch or piece of card stock. There are even brands that make books of filter tips that allow you to roll a filter consistently every time.

To roll a filtered joint, gather the following items:

What You’ll Need:

  • Rolling papers such as Raw or Element brands
  • Cardboard crutch or a 1X2” piece of untreated cardboard stock
  • Fully cured cannabis flower, ground
  • Herb grinder


  1. Begin by grinding about half to one gram of cannabis flower into a soft texture then set to the side
  2. Next, hold the unused filter or card stock by the short side and fold quarter-inch of the filter up toward the opposite end
  3. Turn the filter over and fold another quarter-inch up toward the opposite end so that an accordion shape starts to form
  4. Turn the filter paper over and fold a third time, creating an “M” or “W” shape. There should be just over an inch of unfolded filter at this time. You can also make a spiral shape instead of a “W” if you prefer
  1. Hold the three folded sections together and wrap the remaining unfolded filter around the three folds so that the “W” is wrapped in the rest of the filter
  2. At this point, you should have a round filter with the letter “W” (or “M”) proudly displayed in the middle
  3. You can adjust the size of the filter by tightening or loosening the wrap around the “W. Set your filter to the side
  4. For the next step, hold a rolling paper in your non-dominant hand with the glue strip farthest away from you
  5. Sprinkle your ground bud along the crease of the paper ensuring even distribution across the length of the paper. Place your filter along one side of the paper, usually the side closest to your non-dominant hand
  6. Pinch the rolling paper between your thumbs and index fingers and roll gently back and forth until the cannabis begins taking a cigarette shape
  7. Once the bud has taken form, roll the flower to the base of the paper (closest to your body), tuck the end of the paper closest to you between the rolled flower and the other side of the paper then gently roll up so that the flower becomes trapped inside of the paper. Lick the glue strip on the rolling paper then finish rolling to glue the loose end in place.

If necessary, you can push the filter back inside of the joint, ensuring that there is no gap between the filter and the cannabis inside of the joint. Use a pen or other tool to poke cannabis from the end opposite of the filter deep into the joint then twist the end to hold all cannabis in place and give you an easy place to light your joint. Take a moment to admire your work them spark it up, and enjoy!
