If you are making medibles or tinctures then you want to activate the deactivated cannabinods. What decarbing mean is decarboxylating the cannabis. Or removing the extra CO2 molecule off the canabinods. For example making THCA into THC therefor activating the canabinods. This is what makes the cannabinods medicinal or therapeutic. Decarboxylating happens automatically when smoked because the cannabis gets heated during the smoking or vaporizing process and this is why it is not necessary to decarb cannabis before smoking.
To decarb grind up your cannabis and put it into a mason jar. Then put it into the preheated oven (240F) for 60 minutes.
Once the jar out of the oven and has cooled down. I have a secret step that most people don’t know about. This is trick is only for when making canna-butter or canna coconut oil. This step must be skipped if making any kind of tincture.
Open your jar and add 1-2 cups of water to the decarbed cannabis. The cannabis will absorb the water in 20 mins.
If this step is skipped the dried decarbed cannabis is going to soak up a large part of your base (butter/coconut oil/) instead of the water added here. If you don’t do this you will get less return on your base.
Once the made your base has hardened any extra water can be easily separated from your infused butter or coconut oil.
