Deep learning–enhanced Raman spectroscopy enables accurate identification of synthetic cannabinoids Synthetic cannabinoids, a class of new psychoactive substances, have emerged as a significant public health and social stability threat due to their structural diversity, rapid iteration, and stronger excitatory effects compared to traditional drugs. Their low chemical reactivity and subtle structural variations also make on-site detection and differentiation via covalent reactions extremely challenging.
