Many people are familiar with the cannabinoid THC, but did you know that it comes from the raw acid compound THCa? In this article I will clarify how THCa is converted into THC and list the many benefits of THCa and THC. I will also explain how the percentages of THCa and THC that appear on your cannabis product labels are derived.<\/p>\n\n\n\n
THCa or Tetrahydrocannabinolic acid is the non-psychotropic cannabinoid found in raw and live cannabis. THC or delta-9-tetrahydrocannabinol is the active, psychotropic cannabinoid. They share a very similar chemical composition. <\/p>\n\n\n\n
The difference between the two cannabinoids is the addition of a carboxyl group in THCa. THCa does not bind well with either CB1 or CB2 receptors in our endocannabinoid system. It is not psychotropic due to its 3-dimensional shape and larger size which prevents it from fitting into CB1 receptors. <\/p>\n\n\n\n
It is also thought that THCa, together with some of the other acid forms of cannabinoids, may act to inhibit COX-1 and COX-2 enzymes, resulting in the potential to reduce pain and inflammation. Both these enzymes produce prostaglandins which promote inflammation, pain and fever.<\/p>\n\n\n\n
When the raw form THCa is heated, it is converted into THC through the process of decarboxylation. There are many ways for that to happen that include:<\/p>\n\n\n\n
THC (tetrahydrocannabinol) is the primary psychoactive compound in cannabis that gets you high. When you consume cannabis, THC interacts with the endocannabinoid system in your body, particularly with the CB1 receptors in the brain, producing the characteristic euphoric and psychoactive effects.<\/p>\n\n\n\n
THCA (tetrahydrocannabinolic acid), on the other hand, is the non-psychoactive precursor to THC. THCA is found in raw and live cannabis plants. It does not produce any high because it does not interact with the CB1 receptors in the same way that THC does.<\/p>\n\n\n\n
When cannabis is heated through smoking, vaping, or cooking, THCA undergoes a process called decarboxylation, which converts it into THC, thus making it psychoactive. Therefore, to experience the high associated with cannabis, THCA needs to be converted to THC\u200b.<\/p>\n\n\n\n
In summary, THC is the compound that gets you high, while THCA must be decarboxylated to THC to produce psychoactive effects.<\/p>\n\n\n\n

In addition to all the potential benefits of THCa listed above, additional potential benefits of THC include the following:<\/p>\n\n\n\n
While THC is available in every delivery method of cannabis, THCa is available in topicals, tinctures, capsules and raw cannabis juice.<\/p>\n\n\n\n
Raw cannabis works much differently than cannabis which is decarboxylated. The cannabinoid acids are stored in the body fat known as adipose tissue. It takes approximately 4-8 weeks for full saturation. Once the fat has completely absorbed all the cannabinoid acids, the full medicinal effects are felt. By juicing leaves and buds, patients can increase their daily intake of cannabinoids since their is no psychoactivity involved.<\/p>\n\n\n\n
While THC has been the subject of many clinical human trials, less research has been devoted to THCa.<\/p>\n\n\n\n
A June 2012 preclinical study published in Phytomedicine illustrated the potential for THCa to help protect the brain from the onset of neurodegenerative diseases.<\/p>\n\n\n\n
A 2013 study using animal models and cell cultures demonstrated that THCa may prevent the spread of prostate cancer cells.<\/p>\n\n\n\n
A July 2017 study conducted by the Institute of Plant Sciences, Department of Gastroenterology and Hepatology and the Sackler Faculty of Medicine, Israel, concluded that THCa may possess stronger anti-inflammatory properties than CBD when treating IBD, Crohn\u2019s Disease and Ulcerative Colitis.<\/p>\n\n\n\n
Are you confused by the product labels for THC and THCa on your medical cannabis products? I will do my best to clarify how the percentages of THCa and THC were derived.<\/p>\n\n\n\n
I am sure you are aware that medical cannabis products must go through rigorous testing for many reasons. One of them is to determine the potency of the different cannabinoids in your products.<\/p>\n\n\n\n
There are 2 common processes for testing the potency:<\/p>\n\n\n\n
1. Gas chromatography (GC) in which extracted cannabinoids are converted to a gaseous mixture at high temperatures. They are run through a filter of sorts that measures the different cannabinoid levels.<\/p>\n\n\n\n
The drawbacks in using GC are several fold:<\/p>\n\n\n\n
2. Liquid chromatography (LC) occurs at room temperature and is a better testing method.<\/p>\n\n\n\n
Have ever wondered how labs are able to determine the potency of THCa and THC in your strains? Since it is impossible to know exactly how much THCa converts to THC in any given strain, a universal mathematical formula has been devised for this purpose.<\/p>\n\n\n\n
THCtotal = (%THCa) x 0.877 + (%THC)<\/p>\n\n\n\n
Let\u2019s use the following example to illustrate this. The label lists THCa 22% and THC 3%<\/p>\n\n\n\n
THCtotal = 22% x 0.877 + 3% = 22.3%<\/p>\n\n\n\n
I hope this gives you more of an understanding of how the percentages of THCa and THC that appear on the product labels were determined.<\/p>\n\n\n\n
