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.

  1. 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.

  2. 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.

  3. 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.

  4. 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 use a joint filter

Installing a joint filter is easy. When you go to roll your joint, and have filled the paper with dry herb, simply move a bit from one end and replace it with the filter. Then twist the paper as you usually would, and once done, fold any remaining paper at the opening of the joint into the creases of the filter to hold it in place.
