What is a QWISO extract and how to make it

Cannabis users have come up with many different ways to consume the active constituents within the herb. Extracts are a potent form of cannabis and offer powerful highs to both recreational and medicinal users. The extract world is a rabbit hole within itself, and many different methods exist for pulling THC and CBD out of cannabis flowers.

QWISO, meaning quick-wash isopropyl, is one such method, known to give good yields—even off of small amounts of flower.


QWISO is a cannabis extraction method that utilizes an isopropyl wash to remove trichomes, the glands that produce cannabinoids, from cannabis flowers.

The flowers can be soaked in the alcohol for varying amounts of time to manipulate the quality and potency of the end product. What is left is a resinous, dark amber substance that features high concentrations of cannabinoids.



The following equipment is needed to make QWISO extract:

  • Grinder
  • Unbleached coffee filters
  • Cannabis (10–20 grams for best results)
  • Isopropyl alcohol (food grade 99%, 100–200ml per 10g of flower)
  • Sieve
  • Plate
  • Mason jar
  • Glass measuring jug
  • Small razor blade
  • Air-blowing fan


1. To begin making the extract, you will need to place both your ground flowers in the mason jar and the bottle of alcohol into the freezer (separately) for at least several hours or overnight. By freezing the flowers, it allows the trichomes to be much easier to separate from the plant material.

2. When time is up, take the mason jar and alcohol out of the freezer and pour the alcohol into the mason jar with your flowers. Close the lid and shake the jar thoroughly for 30 seconds. This short period of time defines QWISO as a “quick wash” extract. This is just enough time to extract the trichomes whilst leaving most of the harsh-tasting chlorophyll behind.

3. Next, pour the mixture through a sieve into the glass measuring jug, separating the plant material from the extract. Proceed by placing coffee filters over the mason jar and filtering the extract into the jar. This process can take some time, so be patient.

4. Now that your crude extract has been separated, it’s time to purify it further by removing the alcohol from the cannabinoids. Pour the extract onto the plate or into any container with a flat surface. Because isopropyl alcohol is quite volatile, it will simply evaporate on its own.

Use a fan to assist this process by placing it on the lowest setting to blow cool air over the extract. Conduct this process within a garage or well-ventilated space as these fumes are flammable and slightly toxic. This process can take 12–24 hours.

5. After the evaporation process is complete and no liquid remains on the plate, use the razor blade to scrape the extract from the plate. Use a toothpick to remove the sticky extract from the blade and drop it into a storage container of your choice.


QWISO extract can be used just like many other forms of extract. The strain used will determine the strength and taste of the extract.


Many vaporizers are only compatible with extracts, whereas others use exclusively flowers, and some can accommodate both. QWISO extract can be placed into vapes just like other extracts and ingested either at home or on-the-go with ease. Vaping is known to be safer than smoking and the lower temperatures maintain the taste and offer smoother hits.


QWISO can be used on dab rigs. Heat the nail up with a blow torch until it’s red hot. Use a dabbing tool to place some QWISO onto the nail and inhale from the rig. Dabbing offers an intense and fast-acting high.


The joint is perhaps the most iconic way to smoke weed. It’s both ritualistic and relaxing. Joint rolling is becoming more and more creative, with users dressing the outside of papers with extracts—a process known as twaxing. Heat up QWISO slightly and paint it onto the outside of a rolling paper after rolling a joint for an added kick.
