Oncological Conditions (Cancer)

There are more than a hundred distinct cancers, and roughly one person in four will receive a diagnosis at some point in their life. Almost everyone knows someone who has faced it. Treatment usually means chemotherapy, radiation or both, and those therapies come with a heavy symptom burden of their own. Cannabinoid therapy is not a cure for cancer, and we will never present it as one. What it does is help patients tolerate treatment and hold onto quality of life while they go through it, and the evidence supporting that role is substantial.

Managing Nausea and Vomiting

This is the best-established use of cannabinoids in oncology. Chemotherapy raises blood levels of a serotonin metabolite called 5-hydroxyindoleacetic acid. That compound stimulates chemoreceptors in the brain, and those chemoreceptors trigger nausea and vomiting. Cannabinoids appear to work by downregulating chemoreceptor activity, which reduces both how often emetic episodes occur and how severe they are.

The supporting evidence has been accumulating since the 1980s. Trials have shown reductions in emetic events and in nausea severity among patients receiving chemotherapy. There is also evidence that low-dose cannabis improves the performance of conventional anti-emetic drugs rather than competing with them, which makes it a useful addition to an existing protocol.

The benefit is not limited to chemotherapy. Clinical studies have found cannabinoids helpful for nausea and vomiting associated with radiation therapy and in the post-surgical setting as well.

Appetite Loss, Weight Loss and Cachexia

THC has been shown to stimulate appetite and slow wasting in patients with AIDS and in those experiencing anorexia-cachexia from cancer and its treatment. Holding weight during treatment is not a cosmetic concern; it directly affects how well patients tolerate their protocol and how they recover. The combination of appetite stimulation and reduced nausea is the reason so many oncology patients look into cannabis in the first place.

Pain, Mood and the Rest of the Picture

Cannabinoids interact with receptors that influence pain perception, stress, anxiety and mood, so treatment frequently improves more than the symptom it was prescribed for. Chemotherapy-induced nerve pain and generalised weakness both respond in many patients. So does the anxiety and low mood that accompany a diagnosis, which is not a minor side benefit when patients are facing months of treatment.

What the Laboratory Research Suggests

We want to be careful and honest here, because this is an area where patients encounter a great deal of overstated material online.

The American Association for Cancer Research has reported that cannabis slowed tumour growth in brain, breast and lung tissue. Researchers at the California Pacific Medical Center reported that cannabis may inhibit metastatic spread, based on work with patients showing high levels of ID-1, a protein central to cell growth and cell differentiation. Elevated ID-1 appears in breast, prostate and bladder cancers among others; when high-ID-1 cells were exposed to cannabis treatment, they became less invasive and tumour growth slowed.

This is genuinely promising research. It is not the same as a treatment for cancer, and no patient should substitute cannabinoid therapy for oncological care. At Cura Vida, cannabis sits alongside your oncology team's plan, never in place of it.

Nausea From Any Cause

Nausea is a symptom rather than a disease, and it accompanies a long list of conditions: influenza, food poisoning and salmonella, severe pain, migraine, ulcers, excess alcohol, overeating, strong odours, and cancer and cancer treatment. It may last minutes or persist for days, and it often arrives with diarrhoea, fever, abdominal pain or light-headedness.

Cannabinoid receptors are distributed far more widely than most people expect. They are in the brain, but also in the lungs, liver, kidneys and throughout the immune system, and they influence appetite, pain perception and memory. When cannabinoids engage those receptors the effect is broadly calming, which is why treatment often resolves the abdominal pain and light-headedness alongside the nausea itself.

Taking It Without Making Nausea Worse

Many patients worry that swallowing an oil or a capsule will aggravate the very symptom they are trying to control. In practice there are several ways around that. Sublingual oils are absorbed through the tissue under the tongue and largely bypass the stomach. Vaporised preparations act fastest of all, which suits breakthrough nausea in the hours immediately after a chemotherapy session. Where swallowing is difficult, smaller doses taken more often are usually tolerated better than one large dose. Topical preparations remain an option for localised pain when nothing can be kept down at all. Our physicians build the timing of your plan around your treatment cycle rather than around a fixed daily schedule.

Your Treatment Plan at Cura Vida

Oncology patients receive a comprehensive assessment and a cannabinoid plan coordinated with their treating oncologist. Timing around chemotherapy cycles matters a great deal, and we build that into the plan. Medical cannabis treatment should always be supervised by a qualified physician.
