What Is QWISO (Quick Wash Isopropyl)?
QWISO stands for Quick Wash Isopropyl and is an extraction method where cannabis is washed with isopropyl alcohol to create a potent concentrate.
It’s a popular DIY method among home users because it’s relatively simple and doesn’t require expensive equipment. The result is a type of hash oil or concentrate rich in THC and other cannabinoids.
How Is QWISO Made?
The QWISO process starts by freezing both the cannabis and the isopropyl alcohol (at least 91%) to reduce unwanted compounds like chlorophyll. Then the cannabis is rinsed briefly (usually 20 to 30 seconds) with the alcohol, which dissolves the trichomes.
After filtering the mixture, the alcohol is slowly evaporated—either by air drying or using a gentle heat mat. What remains is a sticky concentrate that can be smoked or vaporized.
How Do You Use QWISO?
QWISO concentrates are usually consumed by dabbing or vaporization, but can also be added to a joint or bowl for a stronger experience.
The texture can range from sticky oil to crumbly shatter-like consistency, depending on the technique and drying time.
When Should You Choose QWISO?
QWISO is ideal for those who want to make their own concentrate at home without complex equipment. It’s faster and safer than butane extraction (BHO), though it’s still important to ventilate well and use clean materials.
QWISO offers a powerful, homemade extract of cannabis compounds. Perfect for DIY enthusiasts seeking a simple and effective extraction process.
