Cannabis sativa L. has been used for centuries as a herbal remedy. It interacts with our body’s endocannabinoid system (ECS), affecting cancer. This interaction can slow down or stop cancer growth.
Cannabinoids are used to help cancer patients feel better. They can reduce pain, stop nausea, and increase appetite. Studies in cells and animals show they can fight cancer in different types.
The success of cannabinoids in fighting cancer depends on the type and how much is used. It’s important to understand how they work in our bodies. This knowledge can help improve treatments for cancer patients.
The Historical Evolution of Cannabis in Medical Treatment
Cannabis has been used for medicine for centuries. It was first used in ancient China during the Han Dynasty. It helped with pain, constipation, and even malaria.
Ancient Medicinal Uses Across Civilisations
In India, Ayurvedic medicine used cannabis too. It helped with many health issues, like brain and breathing problems. It was also used for stomach and kidney issues, and even for infections.
Western Medicine’s Recognition and Prohibition
In the 19th century, cannabis was introduced to Western medicine. It was found to help with pain, vomiting, and even improve mental skills. It was listed in the US Pharmacopoeia in 1851. But, its use declined in the 20th century due to recreational use and new medicines.
Modern Medical Renaissance
Recently, there’s been a lot of interest in cannabis for medicine again. This is thanks to changes in laws in the EU, US, and Canada. These changes have led to more research into cannabis’s health benefits.
Understanding the Endocannabinoid System and Cancer
The endocannabinoid system (ECS) is key in how cancer works. Many studies show it could help treat cancer. The ECS has receptors, endocannabinoids, and enzymes that keep our body balanced.
CB1 and CB2 Receptors Explained
CB1 and CB2 are the main ECS receptors. CB1 is in the brain, and CB2 is in immune cells. Cannabinoids can stop cells from growing, make cells die, and slow tumour growth.
Role of Endocannabinoids in Cancer Cells
Endocannabinoids affect how cancer cells work. They control cell growth, change, and how cells move and grow blood vessels. The ECS can change these signals and stop cancer cells from growing and spreading.
Molecular Interactions and Signalling Pathways
The ECS works with cancer pathways like PI3K/Akt and MAPK. These are important for cell survival and growth. Cannabinoids can start cell death, stop cell growth, and block blood vessel growth in cancer.
Key Component
Function in Cancer
CB1 Receptors
Primarily located in the central nervous system, activation can inhibit cell proliferation and induce apoptosis
CB2 Receptors
Predominantly expressed on immune cells, activation can regulate immune response and inhibit tumour growth
Endocannabinoids
Endogenous ligands that can modulate cancer cell signalling pathways, such as cell growth, differentiation, and migration
“The endocannabinoid system has been studied for its potential therapeutic effects on cancer by modulating pathways involved in cell growth, differentiation, migration, and angiogenesis.”
Research is showing that cannabis oil might help fight cancer. Studies have found that its active parts, called cannabinoids, can stop cancer cells from growing. They can also make cancer cells die and stop new blood vessels from forming.
A study looked at 207 articles about cannabis and cancer. It found that 52% were original research studies. This shows a lot of work is being done to understand how cannabinoids can help with cancer.
But, there’s not much proof from real-life studies yet. Only 14% of case reports showed strong evidence. A big 81% had weak evidence.
Preclinical studies have shown that cannabinoids can affect cancer cell growth.
Out of 207 articles reviewed, 52% were preclinical studies with original data, indicating the growing research focus on cannabis anticancer effects.
Clinical evidence supporting the use of cannabis as an anticancer treatment is currently limited, with most case reports considered to have weak supporting data.
Even though early studies look promising, we need more solid evidence. More clinical trials are needed to see if cannabis oil is safe and effective for cancer treatment. As research goes on, we might find new ways to use cannabis in cancer care.
“The scientific evidence supporting the anticancer properties of cannabis oil is still emerging, with preclinical studies showing promising results, but clinical data remaining limited. Continued research is essential to fully understand the therapeutic potential and practical applications of this natural compound in cancer care.”
How to Use Cannabis Oil to Treat Cancer
Research into cannabis oil for cancer treatment is growing. Some studies show it might help manage symptoms and even slow tumour growth. But, more research is needed to confirm these findings.
Dosage Guidelines and Administration Methods
Studies on cannabis oil for cancer often focus on CBD. Patients take doses from 10 to 800 milligrams daily. THC is also used, with doses from 4.8 to 7.5 milligrams.
People can take cannabis oil by mouth, under the tongue, or on the skin. The choice depends on what works best for each person.
Timing and Frequency Considerations
When to take cannabis oil and how often is a personal choice. It’s best to talk to a doctor to find the right schedule. They will check how well the treatment is working and adjust it as needed.
Safety Precautions and Monitoring
Those using cannabis oil for cancer should watch for side effects and drug interactions. It’s important to keep in touch with doctors. This ensures the treatment is safe and effective.
“The use of cannabis oil in cancer treatment remains a complex and evolving field, requiring careful consideration and medical guidance. As with any treatment, patients should work closely with their healthcare team to develop a personalised plan that prioritises their safety and well-being.”
Different Types of Cannabis Oil for Cancer Treatment
There are many types of cannabis oil for cancer treatment, each with its own benefits. The most common are CBD oil, THC oil, and full-spectrum cannabis oil.
CBD oil is non-psychoactive and has less than 5% CBD, according to the National Cancer Institute. It’s popular for its potential health benefits without the “high” from THC. A 2019 study found that CBD might help kill cancer cells and make them more sensitive to radiation.
THC oil can help with pain and appetite but can make you feel high. In 2020, research showed that cannabinoids might slow down tumour growth in glioma and kill cancer cells.
Full-spectrum cannabis oil has many cannabinoids and terpenes, which might work better together. CBD can stop cancer cells from growing in breast cancer and slow down cancer spread. It can also affect how fast colorectal cancer cells grow, with the effect depending on the dose.
Oil Type
Key Characteristics
Potential Benefits
CBD Oil
Non-psychoactive, typically 1-5% CBD
May encourage cell death and make glioblastoma cells more sensitive to radiation
THC Oil
Psychoactive, may offer pain relief and appetite stimulation
May reduce tumour growth in glioma, kill cancer cells, and prevent migration
Full-Spectrum Cannabis Oil
Contains a range of cannabinoids and terpenes
May offer an “entourage effect” with synergistic compounds, can stop cancer cell multiplication and inhibit metastasis
The right cannabis oil for cancer treatment depends on individual needs and cancer type. Extraction methods like CO2, ethanol, and oil extraction also play a role in the product’s quality.
Cannabis Oil’s Effect on Various Cancer Types
Cannabis oil might help with different cancers, but the evidence is not all the same. Some studies look promising, but the data quality varies a lot.
Breast Cancer Studies
Some studies on breast cancer hint at cannabis oil’s benefits. But, we need more solid research to be sure. A survey showed 42% of breast cancer patients used cannabis for relief, and 46% think it can treat cancer.
Brain Tumour Research
Research on brain tumours, like glioblastoma, is more hopeful. Studies suggest cannabinoids might slow down tumour growth. Two small trials even showed better survival rates in glioblastoma patients treated with cannabis.
Lung Cancer Investigations
Studies on lung cancer and cannabis are mixed. Some say cannabinoids might fight tumours, but smoking cannabis could harm lungs. More research is needed to understand this.
Other cancers like prostate, pancreatic, and leukemia have also been studied. The cannabis plant’s complexity makes it hard to fully grasp its benefits for cancer treatment.
