“Spice paper,” often called synthetic cannabinoid-laced paper or k2-soaked paper, is made by spraying synthetic cannabis over k2 paper or playing cards. Typical paper or plant content is sprayed with synthetic cannabinoids, which can be chemical compounds built to mimic the effects of THC, the main psychoactive ingredient in cannabis. https://buyherbalincens.com/product/k2-clear-paper-spray/
