    The cannabis plant has been used medicinally for thousands of years, all around the globe, for a wide variety of conditions and ailments. For patients with breast cancer, cannabis offers multiple benefits.

    Important Medical Disclaimer

    Please obtain traditional medical treatment for your breast cancer, as there is a relatively high success rate using standard therapies. Cannabis can be used as adjunctive therapy.

    Chemotherapy-Induced Nausea and Vomiting

    The use of cannabis during treatment can help eliminate or minimize chemotherapy-induced nausea and vomiting (CINV) that is often experienced by breast cancer patients who receive chemotherapy.

    Medical Professional Support

    Cannabis has shown to be a highly effective agent for reducing delayed nausea and vomiting. Approximately 80% of oncologists favor its use.

    Cachexia and Appetite Stimulation

    Cachexia, or lack of appetite, is an issue which many chemo patients suffer. It is widely known that cannabis stimulates the appetite, making it ideal for preventing weight loss and maintaining proper nutrition.

    Sleep Improvement

    Although chemotherapy can cause extreme fatigue, sleep cycles are often interrupted in breast cancer treatment. The proper strain of cannabis can greatly improve sleep quality.

    Anxiety and Mental Health Benefits

    Cancer treatment and diagnosis often involves anxiety and worry. Cannabis, particularly strains with moderate amounts of CBD, have been shown to reduce anxiety and allow a calming of the mind.

    Anti-Cancer Properties Research

    Laboratory studies indicate the possibility that cannabinoids may act as anti-angiogenesis agents, apoptosis inducers, anti-metastatic agents, and anti-proliferative agents.

    Administration Guidelines

    A 50-50 balance of CBD and THC is generally recommended. Because of CINV, oral ingestion is not ideal—a tincture designed for sublingual absorption is a good choice.
