Decarboxylation, and what it does

What is decarboxylation? What does it do?

Decarboxylation is a simple process during which cannabis is treated with heat or it is aged to activate its psychoactive and relaxing effects. This process also happens naturally when cannabis dries and ages. That’s right – despite what you may have heard, raw cannabis doesn’t actually contain any psychoactive compounds. The psychoactive ingredient THC only activates when cannabis undergoes heat treatment or when it dries and ages, though it’s important to note that the decarboxylation effect is much stronger when heated rather than when aged.

This is a little background information to help you understand what happens during the decarboxylation process, also sometimes called “decarbing” or “activating” cannabis, and why not all decarboxylated cannabis makes you high.

decarboxylation is a chemical reaction where the COOH carboxyl group of atoms are removed from the cannabis, exiting in the form of H2O and CO2, (water and carbon dioxide). As cannabis grows, it goes through a process known as photosynthesis. During this process, CO2 is absorbed, where it then combines with free hydrogen within the plant to create carboxylic acid. This is known as carboxylation. The main carboxylic acids of interest are THCA and CBDA, the precursors to THC and CBD respectively. When cannabis is growing, it is THCA and CBDA that it contains, not THC or CBD. This is why raw cannabis does not get you high in anywhere near the same capacity as decarboxylated cannabis.

The process of decarboxylation can occur naturally to some degree with time and heat, often as a process of drying cannabis, or being stored too long. But this natural decarboxylation is nowhere near as efficient or potent as human intervention, i.e. smoking, vaporizing or cooking. When this occurs, the CO2 is removed from the acids, turning them into the much sought after cannabinoids.

However, there is another function at play here as well. One that recreational THC enthusiast will be keen to avoid. At around 70% decarboxylation, THC starts degrading into CBN, and it happens at a faster rate than THCA is being converted into THC, causing a rapid and significant drop in THC content. It is also worth noting that at this point, unconverted THCA is turned into CBNA, and CBNA continues to be converted into CBN, causing CBN content to rise even faster. THCA can also turn into CBNA with time and air exposure, which is partly why marijuana can lose its potency with age or improper storing.

Don’t let this scare you though. CBN has its uses, especially for medical oriented users. CBN is associated with being a sleep aid, an antioxidant, and a measure against glaucoma, amongst other things.


As mentioned above, at around 70% decarboxylation THC begins to degrade into CBN, so depending on what you want from your cannabis will define at what temperature you do it, and how long for. Firstly, if you vaporize or smoke your cannabis ,this is pretty much a moot point, as decarboxylation happens instantly, and the only concern (with vaporization) is hitting the right temperature so that you do not destroy the cannabinoids. Manually decarboxylating your cannabis is for those who want to cook with it, or make certain extracts and oils.

Generally speaking, you want to decarboxylate your cannabis at around 106-120 degrees Celsius for between 30 min to an hour. Many people will happily decarboxylate there cannabis at 118-120 degrees Celsius for an hour, and generally, see this as the standard. However, using such a high temperature for this amount of time could be inadvisable (see below). A note for purists: decarboxylating your cannabis above 100 degrees Celsius straight away can cause any leftover moisture to boil and cause cellular damage to your cannabis – degrading its integrity. To avoid this, you can start by heating your cannabis at around 96 degrees Celsius for 15-20 minutes. This should dry out any remaining moisture, making it safe to move onto higher temperatures. This is quite a trivial matter though, and most people would never notice the difference.

  1. Nice read, I just passed this onto a colleague who was doing a little research on that. And he actually bought me lunch since I found it for him smile Thus let me rephrase that: Thanks for lunch!
