K2 spray, also known as synthetic cannabinoids, are chemical compounds sprayed onto dried plant material and then smoked or vaporized for their psychoactive effects. They are the active compound in cannabis, but they can be much more potent and unpredictable. Synthetic cannabinoids can bind to the same receptors in the brain as THC, producing similar effects such as euphoria, relaxation, altered perception, and heightened sensory experiences.
