What is Cannabis Decarboxylation?
Cannabis decarboxylation (“decarbing”) is the process of heating cannabis so its main active compounds become usable by your body. Think of it as "activating" the cannabis.
Why Decarboxylation Matters
Raw cannabis isn't fully "activated." Gentle heat changes THCA into THC, making it ready for use in edibles, oils, and infusions. Without this step, your finished product may be much less potent than expected.
Why Lower Temperatures Take Longer
The THCA-to-THC reaction happens slower at lower temperatures. The benefit is preservation: a longer, cooler decarb keeps more delicate cannabinoids and aromatic terpenes intact, protecting both potency and flavour.
Why High Temperatures Reduce Potency
More heat isn't always better. High temperatures can activate cannabis faster, but they also increase the chance of losing THC and delicate terpenes. The goal is to use just enough heat—not more than you need.
Decarbing — Frequently Asked Questions
For educational and informational purposes only. These times, temperatures, and THC-preservation figures are estimates based on common decarboxylation guidelines. Real-world results depend on your starting material, its moisture content, oven accuracy and hot spots, how finely the material is ground, and many other variables — always use an oven thermometer and adjust to your own results.
