Finally, it is worth highlighting from these publications that the efficacy of cannabinoids against cancer depends on the dose: the higher the dose, the more important the action.

Since it is difficult to obtain high and constant blood concentrations of cannabinoids by consuming cannabis plants in the usual ways (smoking, vaporizing…) most patients use extractions of cannabinoids. We greatly appreciate the research work carried out by Dr Manuel Guzman’s team at the Universidad Complutense de Madrid for their current work on the use of cannabinoids against cancer.
