Human beings have had a close relationship with the cannabis plant for thousands of years. Yet the science of medicinal cannabis and its therapeutic properties are only just beginning to be uncovered.

What is CBD?

Cannabidiol or CBD for short is one of many cannabinoid molecules produced by the cannabis plant. CBD is second in abundance only to  THC or tetrahydrocannabinol, which is the primary psychoactive compound famous for the “high” cannabis produces when consumed in its natural state.

These plant-based cannabinoids, or phytocannabinoids act on human’s cannabinoid receptors which are a part of the endocannabinoid system or ECS which all people have. Endo meaning inside or within. Phyto meaning from plants.

CBD’s effect on the body

CBD oil interacts with your body’s receptors, including the cannabinoid, dopamine, opioid and serotonin receptors. The science suggests CBD slows the breakdown of cannabinoids and proteins already present in the body.

This modifies the receptors and optimises your system to have greater access to essential compounds, allowing our bodies to access them more efficiently.

The speed at which CBD takes effect varies significantly from person to person, and several factors can come into play, including:

  • Size of the dose
  • How it is administered
  • How often the oil is being taken
  • The metabolism of the person

THC and CBD affect the system in different ways. The primary ESC receptor in the brain, called CB1, is activated by THC. However, CBD does not affect CB1 and has actually been found to restrict or stop compounds like THC from activating this receptor.

CBD oil may provide benefits without the sometimes disorientating and distorting effects of THC.

Even though CBD oil won’t get you “high”, it is still illegal in Australia without being prescribed by a doctor and dispensed by a registered pharmacist. As medical CBD oil is a relatively new product, international standards of production vary; however, in Australia, Co2 extraction is the most common method of medical-grade CBD oil extraction.

How is CBD consumed in Australia?

CBD oil can be administered like most other cannabis products. The means of taking CBD oil will probably come down to the method that makes the user most comfortable. These methods may include:

  • Tincture under the tongue via a dropper
  • Vapourising and inhaling
  • Capsules
  • Lozenges
  • Sprays

Most methods of administration are trialled and adjusted under the guidance of the user’s doctor.

CBD oil side effects 

Some people who use CBD oil report positive and beneficial responses to it, however, clinical research has shown cannabidiol may trigger side effects.

Depending on the individual, the CBD to THC ratio, and the size of the dose, some people may experience:

  • Anxiety
  • Dry mouth
  • Changes in mood
  • Diarrhea
  • Dizziness
  • Drowsiness
  • Nausea

Also, it’s important to note that some individuals may be allergic to and may react to the carrier oils used in the medicine, the three most common types of carrier oils are:

  • MCT Oil
  • Hemp Seed Oil
  • Olive Oil

Some people claim that their CBD or THC product is causing them side effects when really it’s just the fact that they’re allergic to the carrier oil that is used.

The effects of CBD or any medicinal cannabis product can vary greatly, and patients will initially have to do some experimentation under the supervision of their doctor to find the right balance for their treatment.

The options for types of CBD oil include:

  • PCR hemp oil or PCR CBD oil
  • CBD Isolate
  • Broad-spectrum CBD
  • Full-Spectrum CBD

CBD’s function within the body is correlated with CB1 and CB2 receptors. It provides a calming and soothing effect and acts as an inverse agonist of CB2 receptors, which reduces the impact of cannabinoids which usually make CB2 receptors less responsive.

CBD interacts mildly with the cannabinoid receptors, helping other cannabinoids to be better absorbed with many positive effects on cannabinoid receptors, offering far-reaching soothing and relaxing effects.

To date, the majority of CBD’s observed effects are well studied and explained; however, some effects still await discovery.
