Every product batch should have their potency tested, therefore it should not matter what source the potency comes from like hash, butter, C02 extract, butane extract, etc. If you are consuming a gummy that does not have its potency listed or a potency test associated with it, then you are effectively eating it blindly and don’t know what you’ll get. Not recommended.
The overall effects are determined more by the strain(s) of the source rather than the type of extract for example sativa, indica, hybrid. The cannabinoid is also a factor for effects: THC, THCA(non-psychoactive), CBD, CBDA, etc.
