Introduction to THC
The story of THC discovery begins in the 1960s when the compound was first isolated and synthesised. This groundbreaking achievement accelerated our understanding of the psychoactive effects of cannabis plants. It paved the way for decades of research into the properties and potential applications of this prominent cannabinoid.
Background and discovery
Israeli scientist Dr. Raphael Mechoulam first isolated THC in 1964, revolutionising the way researchers viewed and studied cannabis plants. This marked a critical advancement in decoding the cannabinoids responsible for the 'high' sensation individuals experience when using cannabis.
Since then, THC has been a primary focus for researchers investigating both its psychoactive and therapeutic effects.
The past few decades have witnessed significant strides in understanding the complexities of THC and its interactions with the human body, altering mood, perception, and physiological processes. These discoveries have fuelled ongoing research into how THC can be harnessed for potential medical applications.
The chemical structure of THC
THC, scientifically known as delta-9-tetrahydrocannabinol, is unique in its molecular composition. The compound's chemical structure highly binds it to the brain's CB1 receptors, accounting for the ensuing psychoactive effects. When THC interacts with the endogenous cannabinoid system, a series of events unfolds, compromising mood, perception, and various physiological processes.
"The chemical structure of THC enables it to bind powerfully to the brain's CB1 receptors, triggering the psychoactive effects characteristic of cannabis."
Comparing THC with other cannabinoids
Among the vast array of known cannabinoids, THC and CBD (cannabidiol) have garnered the most attention in the scientific and medical communities. The following table contrasts the primary properties of these two distinct compounds:
| Property | THC | CBD |
|---|---|---|
| Psychoactivity | Yes | No |
| CB1 receptor affinity | High | Low |
| Mood and perception alteration | Significant | Minimal |
Consult a certified medical professional for guidance on the appropriate THC dosage and administration based on your specific needs and medical conditions.
For the synthetic THC preparations, nabilone and dronabinol, specific dosage guidelines are provided along with instructions on timing, especially around chemotherapy sessions for patients undergoing cancer treatment.
| Drug | Available dosages | Common starting dose | Administration notes |
|---|---|---|---|
| Nabilone | 1 mg and 2 mg capsules | 1-2 mg per day (total daily dose) | Take 1-3 hours before chemotherapy and repeat twice daily as needed |
| Dronabinol | 2.5 mg, 5 mg, and 10 mg capsules | 2.5-10 mg per day (total daily dose) | Take 1-3 hours before chemotherapy, and every 2-4 hours after that (up to 6 doses per day) |
The adverse effects of THC
While the therapeutic potential of THC has been recognised for various medical conditions, it is essential to be aware of the possible adverse effects and risks associated with its use.
The side effects of THC can be both psychological and physiological, and their severity varies depending on the individual and their level of exposure to the psychoactive compound.
One of the primary negative impacts of THC on mental well-being is the potential for inducing anxiety and paranoia, particularly in individuals predisposed to these conditions.
The feeling of heightened alertness and worry can lead to panic attacks and significantly impair daily functioning. Additionally, THC can cause temporary impairments in cognitive functioning, including:
- Short-term memory loss
- Difficulty concentrating
- Decreased problem-solving abilities
- Impaired motor skills and coordination
In some cases, the psychological effects of THC can also include distorted sensory perceptions, such as hallucinations and delusions. These effects may be more common in individuals with a history of mental health disorders, especially when using high doses of THC.

The future of THC
As the landscape of cannabinoid research continues to evolve, so does the potential for unlocking further therapeutic applications of THC.
Upcoming trends and developments in the field include a wider range of medicinal uses, a deeper understanding of pharmacogenomic interactions, and a progression in legal regulations that could ultimately lead to increased accessibility and acceptance of THC-based treatments.
Investigations into the broader therapeutic potential of THC may uncover novel indications for its application, broadening the scope of conditions that can benefit from its unique properties.
Alongside these discoveries, researchers are delving into the intricacies of pharmacogenomic interactions, which involve understanding the individual's genetic response to THC and tailoring treatment accordingly. This personalised approach may optimise the potential therapeutic impact while minimising unwanted side effects and adverse reactions.
Legal developments in many parts of the world are gradually shifting towards a more accepting stance on THC and its medical potential, with several countries altering their regulations in favour of allowing access to cannabinoid-based treatments.
These advancements provide hope for both patients and researchers alike, as they signal a more profound recognition of the latent opportunities within the realm of cannabinoid science.
