K2 Spray is often used by smoking or vaporizing it. The artificial cannabinoids are sprayed onto plant materials, which happens to be then smoked or vaporized in an identical method to purely natural cannabis. Some buyers also dissolve K2 Spray within a liquid and use it in e-cigarettes or vaporizers. https://k2spray01111.pointblog.net/everything-about-k-2-spray-75732507
