However, when combining CBD oil or other cannabis treatments with existing treatment protocols, you should be monitored for signs of over medication.

How do cancer patients benefit from THC, CBD and hemp oil for cancer treatment?

We have paved the way in developing and proving breakthrough cancer treatments for our patients. Simpson Oil developed the revolutionary M-series of treatments which offer patients the full benefits of THC, without the associated ‘high’.

Simply put, when THC binds with CB1 or CB2 cannabinoid receptor site on the cancer cell, it induces an increase in ceramide synthesis that leads to cell death. Healthy cells in the body do not produce ceramide when near THC; therefore they are not affected by the cannabinoid. Ceramide disrupts the chemistry in cancer cells and causes cancer cell death.

It is why patients with advanced stages of cancer, in remission and even those receiving chemotherapy rely on cannabis treatments.

Our THC and CBD suppositories, introduced rectally, are extremely bio-available. They offer 50% – 70% efficiency, much higher than oral or inhaled THC treatments. Oral treatments are 20% efficient and inhaled treatments offer efficiency ranging between 15% – 25%.

Will medical cannabis treatments give me a high?

No! There is stark distinction between cannabis for recreational use, which gives the ‘high’ and THC and CBD for medical use. The way medical cannabis, THC and CBD are formulated, they don’t give the feeling of the high. A number of natural compounds are used to nullify the unintended psychoactive effects of THC and CBD treatments.

Cannabis treatments are carefully formulated, like traditional medicines, to provide controlled effects and minimize side effects. In fact, CBD and THC have exhibited negligible to no side-effects. This has been achieved with a combination of research, and the naturally beneficial properties of cannabis compounds.

Is CBD oil legal? Is THC legal?

Countries around the world have different laws governing cannabis. The recreational use of cannabis is restricted to a handful of countries, such as Canada. However, medical cannabis is far more widely accepted. It’s how patients around the world are able to benefit from Rick Simpson oil treatments for cancer and more.

Hemp products have been legalized in many countries, including the United States of America. This follows extensive public research into the benefits of THC and CBD treatments in the European Union, the United Kingdom, Australia and more.
