K2 Powder is typically used by cigarette smoking or vaporizing it. The synthetic cannabinoids are sprayed onto plant materials, which can be then smoked or vaporized in the same way to normal cannabis. Some end users also dissolve K2 Powder in the liquid and use it in e-cigarettes or vaporizers. https://knoxglygr.bloguetechno.com/about-k2-spice-67426537
