Sweet and sour, like a crisp green apple. Atomic Apple is the hybrid in the Ultra Gummies line, with 20mg of THC in each of its five pieces. The THC comes from the same cannabis oil Heavy Hitters uses in its vape cartridges, and the brand calls these its heaviest-hitting gummies. They're made with pectin and are gluten-free, dairy-free and nut-free. Go easy at first: half a gummy, then a wait of 30 to 90 minutes, because a whole one is a strong dose.
