Weed Decarboxylation: How to Decarb Cannabis

Decarboxylation is activating compounds or cannabinoids by heating cannabis to a particular temperature. This process converts cannabinoids, a group of compounds THCA and CBDA, into THC and CBD. In the absence of Decarboxylation or decarbing, we will not be able to know a lot of health benefits of the plants. But, on the other hand, you will be able to relish medical cannabis and can create edible foods at your home when you get to know everything about decarbing.

Why Decarbing cannabis is important

THC (the primary psychoactive compound) is not enough in raw cannabis. That’s why the natural cannabis flower does not make you feel high, nor does CBD, a cannabinoid known for curing anxiety and depression.

In scientific terms, Decarboxylation eliminates organic acid carbon dioxide from the carboxyl group. The molecular form of the carboxyl group is the carbon atom or COOH, a chemical bonded to an oxygen or an OH group. Decarboxylation naturally arises at a prolonged rate. Still, it can precipitate when the heat is applied to a molecule, allowing it to break down and release carbon dioxide.

Remember to decarb edibles at a lower temperature.

Decarbing of cannabis is generally done in high temperatures. On the other hand, you are decarbing a joint, bong, or vape pen by applying heat to them. But edibles like cannabis should be decarbed at lower temperatures for longer as cannabinoids can burn off quickly when you use the wrong temperature or decarbing it for too long. Cannabinoids can also be preserved when the decarbing of edibles is done for a more extended period on a lower heat (mainly THC, which produces psychoactive effects) along with terpenes (a compound found in plants which gives flavor to cannabis)

In addition, THCA is converted to THC when Decarboxylation is done at a lower temperature.
Let’s know more about how to decarb in detail.

Does heating up Weed make it stronger?

Heating makes cannabis stronger because decarboxylated Weed contains psychoactive compounds. The process of heating weed is essential as it converts THCA and CBDA into THC and CBD.

Should you use a grinder before decarbing?

The cannabis community debates whether, before decarbing, the flower should be ground in the grinder or simply by hand. Cannabis consumers who consume seasonally say using hands to break the flower derange trichomes (small hair on unicellular buds). On the other hand, it is said that for some people, it is an integral part of the ritual and experience to feel the cannabis with your hands.

Breaking cannabis with your hands prevents stickiness and leaves your fingers sticky. It is because the trichomes stick to your skin which also loses some potency. Many people who use the grinder method say that using a three-chambered grinder collects knives. In addition, one can also use the decarbed kief in cannabis edibles, tinctures, cannabutter etc. There are different varieties and prices of grinders available, but it depends on whether you use them or not.
