“Cannabidiol may attenuate tumor growth in a number of other systemic malignancies.
Decreased tumor growth in pulmonary malignancies is seen after administration of cannabidiol.
Tumor metastasis also is markedly attenuated.
Similar attenuation of tumor growth is seen in breast malignancies.
The above examples clearly illustrate the significant antineoplastic effects of cannabidiol.
Hopefully, the next few years will see increased studies to fully and further evaluate these antineoplastic effects.”
