The heat decarboxylates the THCA (tetrahydrocanabinoic acid) and isomerizes the CBN/CBD (canabinol/canabidiol) to THC. The ideal temperature is somewhat like 105 C. It is why some people says the weed must be "activated" by heat to be effective. Simmering the weed in boiling water does it. And heating it by any another means too, more or less effectively. So, as microwaving the weed will heat it at +-100C, it must work (at least in theory)
And you are right in questioning, cause is the better way to learn
Coelho Reviewed by Coelho on . How to increase the potency of MJ Here there is something i think is the dream of every stoner... how to increase the potency of hemp... and the recipe is very simple: "The potency of marijuana can be increased by about 50% simply by simmering a water slurry of the material for 2 hours. Add water as necessary to maintain the level. Cool and filter the mixture, and refrigerate the aqueous solution. Dry the leaf material at low heat. Drink the tea before smoking the marijuana. The effects are much more intense and last longer Rating: 5
