The analysis of cannabinoids in e-cigarette liquids using LC-hRaM-MS and LC-UV.

The text discusses the analysis of cannabinoids in e-cigarette liquids using LC-hRaM-MS and LC-UV methods. The study found that none of the analyzed samples exceeded the legal limit for total ThC content, but only 30% of the samples had CBD content within 10% deviation of the label claim. additionally, "full/broad spectrum" CBD e-liquids contained several minor alkaloids in comparison to "classic" CBD e-liquids. The authors suggest that quality controls are necessary for CBD e-liquids, especially concerning label accuracy.
