introduction
synthetic cannabinoids were first marketed as legal marijuana alternatives in europe in the early 2000s. the first SCs were in herbal form and small packages. "street chemists" named and launched these smokable herbal products under the "spice" brand. the popularity of "spice" rapidly increasedwith the help of their legal sales. although package labels clearly indicate "not for human consumption". "incense", or"for aromatherapy use only", clinical toxicologists understand these products are commonly used to obtain ∆9-THC-like psychological effects.
