Biosafety assessment of cannabidiol CBD) in primary neurons. The cells were treated for 24 h with CBD (1–25 μM). Cell viability (A) and cytotoxicity (B) were estimated by MTT reduction and LDH release assays, respectively. The data were normalized to vehicle-treated cells and are presented as the mean ± SEM from 3–8 independent experiments with 3–5 replicates. *** p < 0.001 vs. vehicle-treated cells.
