I've always eaten it with a bit of cheese or melted it into chocolate.

For me, approx 4g of paste, melted into 200g of chocolate and poured into a mould that gives 30 pieces gives a strong effect on one piece (after an hour or so).

So that would have about 133 mg of paste in each piece, of which half is zeolite, leaving 60mg of unknown composition converted CBD in each one. I see "strong" gummies typically have 10-20mg THC in them, so I guess my conversion isn't at the 50% mark yet. Some batches have definitely been stronger than others. This is without using any oxygen exclusion techniques, just a foil packet in the oven.

Anyway, I guess I'm saying that in my experience I'd definitely find 0.5g of  my product somewhat overwhelming, so maybe adding a bit of fat really makes a difference in effectiveness.
