Here's a weird question: do you have a gallbladder? People without a gallbladder tend to have that experience with edibles, or need a higher dose to get an effect.
I think I'm one. Tried weed multiple times in different types but never had any sort of experience let alone enjoyable one. Smoke a joint, just get sore lungs. Eat edibles? Bleh, just a gross tasting candy.
Only time I felt anything was after a 50mg gummy, and that was just a bit of light headedness for a half hour.
Are you a ginger? Do you need more time for anesthesia to take effect or for your gums to be numb after dentist shots?
I'm working on a theory that if you have a high tolerance to the numbing stuff then the edibles don't really work for you. I know someone that tried all different edibles cause they worked at one of the stores that sold it. None of them worked, except when they really overdid it and had a whole mushroom bar. Even then it was minor. Edibles just don't effect some people.
