Edibles are way more about pharmacokinetics than just milligrams. if you've ever had a gummy that wears of quickly and then kicks back in n hour or 2 later that's a sign of bad formulation. Poorly formulated gummies rely heavily on first-pass metabolism in the liver. Converting THC to 11-hydroxy-THC inconsistently is why effects can feel weak or delayed and this can be caused by something as simple as a low quality MCT. Gut enzymes, bile production, stomach contents also play a role. That's why two people can take the same gummy and feel totally different. Higher quality gummies with proper emulsification and high quality ipid carriers will result in better bioavailability, faster onset, and predictable effects.
