Effects of individual drugs on cell viability. Cell viability of T24 and TCCSUP cells was assessed after 48-h treatment with various drugs in a concentration-response experiment. A All cannabinoids tested in the study in T24 cells are compared in the same graph. B Cisplatin alone. C Gemcitabine alone. D Δ⁹-Tetrahydrocannabinol alone. E Cannabidiol alone. F Cannabichromene alone. G Cannabivarin alone, in the indicated cell lines. Results are means ± SEM of at least 3 independent experiments
