I found this about them (assuming the brand was Wana). I don't know if others use the same technique. They claim they also don't give an edible high.
"It all comes down to a pretty simple concept. We like to call it “the oil and water problem.”
You may not know that cannabinoids like THC and CBD are actually lipids, otherwise known as fats. Your body is made of something like 70% water. Fats (like oil) and water don’t mix well. So when you ingest cannabinoids, your body has to work really hard to absorb and metabolize them.
In the case of Wana Quick Gummies, we’ve tackled this problem by harnessing an innovative new technology known as Azuca’sTiME (Thermodynamic individual Molecular Encapsulation). TiME encapsulates each tiny THC molecule in a water-soluble layer. Think of this layer as a kind of disguise that tricks your water-based body into absorbing the fatty THC molecules.
This watery disguise means the THC in Wana Quick Gummies can enter your bloodstream before it undergoes first pass metabolism in your liver. This means it hits much faster than in traditional edibles – typically between 5 and 15 minutes. But it also means that the Delta-9-THC is never converted into those more intense, body-focused 11-Hydroxy molecules.
The result? A fast-acting edible that actually feels like smoking!"
