CBD Could Inhibit Tumor Growth in Multiple Cancer Models

WRITTEN BY: Laurence Tognetti, MSc

How can cannabidiol (CBD) combat cancer tumors? This is what a recent study published in Phytomedicine hopes to address as a team of researchers from China investigated CBD’s promise in being used as an anti-tumor agent. This study has the potential to help scientists, medical professionals, legislators, and the public better understand the health benefits of cannabis and how it can be used to treat life-threatening diseases.

For the study, the researchers examined CBD’s promise as an anti-tumor agent by evaluating its effectiveness on various types of cancer, the use of various types of therapies, including nano-based drug delivery, and safety efficacy. The goal of the study was to enhance our understanding of CBD’s use as an anti-tumor agent in combating cancer and how this can be further studied in the future. In the end, the researchers concluded that CBD holds great promise in its potential use as an anti-tumor agent, noting these findings can be used as a baseline for future studies.

The study notes in its summary, “Cannabidiol (CBD), an FDA-approved and well-tolerated compound, demonstrates promising antitumor effects by inhibiting cancer growth, metastasis, and angiogenesis, while also alleviating cancer-related symptoms such as pain and nausea. However, its clinical translation requires further pharmacokinetic optimization and validation in combination therapies.”

This study builds off several recent studies that explored CBD’s anti-tumor effects, processes, and potential therapies. This includes a 2025 study published in Frontiers in Pharmacology that explored CBD’s and THC’s role in combating ovarian cancer and another 2025 study published in International Journal of Molecular Sciences that explored CBD’s role in targeting human cancer cells.

How will CBD be used to treat cancer tumors in the coming years and decades? Only time will tell, and this is why we science!

As always, keep doing science & keep looking up!
