Tetrahydrocannabinol or delta-9 tetrahydrocannabinol (THC) is one of the few cannabinoids that needs no special introduction, especially to people who understand cannabis and its numerous applications for medical and recreational purposes. The mind-altering activity of the compound makes it one of the most popular cannabinoids on the market.
The role of THC in the cannabis industry cannot be overemphasized, as it has played a key role in choosing strains and is a major factor in determining the safety and legal status of products.
Unlike THC, THCa doesn’t get you high. Although THCa turns into THC, It is one of the less researched cannabinoids, thanks to its limited concentration in the cannabis plant. The fact that it is a major component of raw cannabis products and easily gets converted to THC makes it harder to study. It is also pertinent to note that it is quite impossible to get high from consuming THCa and/or raw cannabis.
The raw cannabis plant is a storehouse of nutrients. It is often considered a superfood since it has a high nutritional value. The flowers, seeds, and leaves of the cannabis plant are rich in several nutrients that can play therapeutic and nutritional roles. The raw cannabis plant is also rich in inactive or what we call acidic cannabinoids, explaining why it is almost impossible to get high from eating raw cannabis.
The seed, flower, and leaves of the cannabis plant contain varying concentrations of the following nutrients/ compounds.
A quick look at this list, and you can appreciate the benefits of raw cannabis juicing or adding it to your morning smoothie.
These cannabinoid acids so prevalent in raw cannabis represent the inactive forms of the compound and are very important in creating the neutral/active form such as THC or CBD.
Essentially, these cannabinoid acids start as cannabigerol acid (CBGa) and are further converted to tetrahydrocannabinolic acid (THCa), cannabidiolic acid (CBDa), cannabichromenic acid (CBC), and more. These acidic cannabinoids are later converted to their neutral forms, THC, CBD, CBC, and CBC.
Although regarded as inactive cannabinoids, there are quite a few research studies that support the possible therapeutic potentials of cannabinoid acids.
For instance, a 2022 study shows the possible antiviral properties of CBGa, THCa, and CBDa in preventing the attachment of Covid-19 viral particles to host cells.
Cannabinoid acids may possess a better therapeutic activity than their neutral counterparts. For example, CBGa was found to be a better antioxidant agent than CBG. Another study in 2021 reported how acidic cannabinoid (CBGa) provided a better anticonvulsant activity than CBG. These and many more therapeutic activities are responsible for the increased interest in cannabinoid acids.
When comparing THC to THCa, they share some similarities and differences. Although they originate from the same plant, they exhibit different levels of interaction with the body, thus suggesting a unique therapeutic potential for each. Let’s dive into their world.
THC is one of the most abundant cannabinoids in the cannabis plant. It constitutes a large percentage of phytocannabinoids (depending on the strain) and is responsible for the psychoactive effect of cannabis. Note that delta-9 THC is one out of the 11 members of the THC-type cannabinoids.
The other compounds that may share a structural similarity with THC include;
- Delta 10-THC
- Delta-11- THC
Variants of the THC-type phytocannabinoid exhibit varying levels of psychoactivity.
While these compounds originate from different THCa molecules usually designated with the appropriate numbers, e.g., delta-9 THCa, delta-8-THCa, THC is a general term referring to delta-9 THC since it is the first THC to be synthesized in the plant.
Thanks to its psychoactive nature, THC is one of the most researched cannabinoids. Although it can interact with different parts of the body, it has a higher affinity for receptors that are mostly expressed in the central nervous system (these are called the CB1 receptors).
The receptors play a critical role in controlling mood, pain, and other feelings, thus explaining why THC can produce euphoric feelings. Some of the therapeutic benefits of THC are listed below:
THC’s most visible psychological effects have been divided into four groups; affective, sensory, somatic, and cognitive. The CB1 receptor mediates THC’s most documented side effects since they are present in the central nervous system. Some of the possible side effects of THC are listed below:
Tetrahydrocannabinolic acid (THCa) is one of the major constituents of fresh and undried cannabis. It is the inactive or neutral form of THC. It is the precursor cell for the creation of THC, CBN, and other variants of tetrahydrocannabinol like delta-8, delta-10, and delta-11 THC. It is naturally present in the cannabis plant and is synthesized from CBGa (the mother cannabinoid) via enzymatic activity. THCa is further decarboxylated into THC in the presence of heat. By exposing THCa to oxidation, it gets converted to CBNa and delta-8-THCa.
As one of the major constituents of raw cannabis, THCa is a non-psychoactive cannabinoid whose benefits are absorbed by the body via the raw consumption of flowers such as cannabis juicing. It is unstable and converts to THC or other psychoactive cannabinoids in the presence of heat or light.
THCa is not only good for creating other cannabinoids. Research shows a varying degree of therapeutic activities. Some of these activities may be triggered by its interaction with several cannabinoid receptors.
These receptors regulate energy production, lipid metabolism, and inflammation. This supports the use of THCa as a neuroprotectant in Gliosis and Huntington’s disease, for example. THCa also exhibits a weak affinity on CB1 receptors with no activity on CB2.
The other therapeutic benefits of THCa are listed below;
THCa is non-psychoactive. While this is not as widely researched as THC and other neutral cannabinoids due to its limited availability and unstable nature, some people believe it may share a similar side effect with THC. There is a likelihood of developing sensitivity to THCa if you are sensitive to THC. On this note, some of the possible side effects that may arise from THCa include:
Also, note that this may show up on drug tests, especially if you consumed the cannabinoid a few days before the drug test. THCa may also interact with prescription medications processed by the CYP450 (similar to how grapefruit interacts with certain meds).
THC is a psychoactive cannabinoid that can trigger many psychotropic activities. This is due to interaction with CB1 receptors. Note that CB1 receptors are expressed in the basal ganglia, cerebellum, and cortex. These brain parts coordinate movement, pleasure, memory, and thinking. THCa is non-psychoactive and may provide a safer interaction and therapeutic activity.
THC is considered illegal in several world regions, with acceptable limits of less than 0.3%. These regulations are silent on THCa. While THCa has not been classified as a controlled substance on the federal level possessing it could land you in trouble if you decarb cannabis.
The therapeutic activity of cannabinoids depends on their interaction with receptors. While THC strongly interacts with CB receptors, THCa prefers to bind with PPaRγ receptors.
THCa is highly unstable since exposure to heat or light can convert it to THC, delta-8 THC, or CBN. This is why it is quite impossible to obtain the cannabinoid. However, certain cannabis strains are rich in THCa.
