If you’ve been smoking for decades I can see how edibles won’t do much, your receptors are flooded with so much Delta-9-THC rather than 11-Hydroxy-THC which is a more advanced molecule.
If you want to enjoy edibles you have to stop smoking to reset your cannabinoid receptors to flush out all the Delta-9-THC so your liver can start making 11-Hydroxy-THC from the Delta-9-THC is gets from the edibles, the blood vessels of your bowels have to pass through your liver first, and it regulates how much of it enters your blood stream, this way you can eat some before breakfast and be good all day long, your liver is smart enough to release it slowly for maximum benefit.
Decarb your bud in two batches at 212 F / 100 C “sous vide” (put a lid on the cooking pot containing the bud), let it all decarb together for 1 hr 11 mins, then take out half, and let the other half go on until 2 hr 22 min.
Eat 1/3rd of a teaspoon of each batch before breakfast.
This method creates a much wider spectrum of cannabinoids, specifically a more even ratio of THCa, THC, and CBN, rather than just THC.
So ingesting a nice balance of all three also creates a more balanced peaceful effect.
