You can eat it raw but it won't be as effective, when I was eating a bunch of d8 I would usually just melt it in a little butter and put it on bread or throw it in a cup of coffee. D8 butter in coffee was probably my favorite method tbh
The gummy measurement might be 7g in the whole container, one company sent me a bottle of gummies for free and I initially thought they were 800mg gummies, turns out that was just the amount of total cannabinoids in the whole container
