Frequently Asked Questions

Decarboxylation is the process of heating cannabis to convert inactive THCA into active THC (and CBDA into CBD). Without decarbing, eating raw cannabis will produce little to no psychoactive effect. It's an essential step before making cannabutter or any infused edibles.
The most common method is 110°C (230°F) for 30-40 minutes in a conventional oven. This temperature range activates THC without degrading it. Higher temperatures risk destroying cannabinoids. Follow our step-by-step guide on how to decarb weed in the oven for best results.
While technically possible, microwaving is not recommended for decarboxylation. Microwaves heat unevenly and can create hot spots that destroy cannabinoids. An oven or sous vide method provides much more consistent results. See our dedicated microwave decarb guide if you want to try it.
Properly decarbed cannabis will turn from green to a golden-brown color and feel dry and crumbly to the touch. It should smell toasted and aromatic. If it turns dark brown or black, it has been overheated. Once decarbed, use it to make cannabutter or add it directly to recipes.
Yes, decarboxylation produces a noticeable herbal smell. To minimize odor, you can use a mason jar method, oven bags, or a sous vide setup. These sealed methods significantly reduce the smell during the process. For further tips, see our guide on reducing cannabutter odor.
