"Synthetic cannabinoid receptor agonists (hereafter synthetic cannabinoids) are a chemically diverse group of synthesised compounds that often act on similar receptors to those acted on by Δ-9-tetrahydronnabinol in cannabis. Powders are typically dissolved in solvent, sprayed on inert plant material and then smoked, and are often sold as commercial mixtures (eg, Spice, Kronic).12 Other forms and routes of administration include ingestion of pills or powders, and vaping using solutions containing synthetic cannabinoids. Effects can be similar to those resulting from use of cannabis (eg, euphoria, sedation, and drowsiness), but are typically more severe and sometimes unique from cannabis.13"
