The THC that is found in the cannabis flower that you buy or grow is not activated for use in edibles and topical creams. That means that unless you take the right steps to prepare your cannabis, you’re missing out on many of the benefits.
THC activation happens when the cannabis is heated in a process called decarboxylation or decarbing. This can be accomplished by using an oven on low heat to roast the cannabis. The longer the cannabis is heated the more THC is used up, so darker brown colours indicate less potency.
