What is the difference between THC and THCA?

THCA is a precursor to THC. The difference between THCA and THC is THCA is non-psyhcoactive and THC is. THC is the most famous cannabinoid found in marijuana plants and is responsible for getting people stoned. THCA is not federally scheduled drug while THC is. That is interesting because THCA turns into THC usually with the application of heat.

How does THCA convert into THC and what is decarboxylation?

THCA is abundant in live and raw marijuana. When you dry marijuana, some of that THCA will naturally convert into THC. The process of converting THCA into THC with heat expedites the conversion and is referred to decarboxylation or as “describing” your marijuana. From a scientific viewpoint, decarboxylation is a chemical reaction where a carboxyl group and releases carbon dioxide. Interestingly enough, the reverse process is called carboxylation and is the first step in photosynthesis.



How to measure the real potency of your cannabis?

When you are testing the potency of marijuana, it is important to factor in both THC and THCA. THCA content is important even though it is non-psychoactive because it will eventually turn into THC.  There is a formula which takes THCA in account for total THC % content of your cannabis. This formula is as followed: Total THC % = 0.877 * (THCA %) + (THC %). This will give you the real potency of your cannabis.

What are some of the medicinal properties of THCA?


It is important to note that while THCA is not psycho-active, this cannabinoid does have its own medicinal properties. It shows to be an anti-inflammatory, a neuroprotectant, an anti-vomitting agent, and has shown to ward of prostate cancer. This cannabinoid can also aid in sleep and suppress muscle spasms. THC also has some of these medicinal properties along with making people feel “high”.

What is the optimal temperature for the decarboxylation of your cannabis?

The desired temperature to convert THCA into THC should be kept at a temperature no greater than 222 degrees Fahrenheit.
