Concentrates come in many forms, but all are procured through an extraction process which strip extraneous compounds from the plant and leave behind concentrated cannabanoids in the resulting product. Some concentrates test as high as 80%THC or CBD and can produce a 'high-less', but altogether painless experience. Concentrate types include, kief (dry sift or pollen), hash (compressed resin), hash oil, CO2 oil, CBD oil & RSO, and tinctures (liquid concentrate).
