CBD vs. THC: What you need to know

The use of medical cannabis to help manage or alleviate symptoms related to a significant number of conditions continues to gain in popularity in Canada. Currently there are more than 70,000 authorized users, and that number is expected to grow to almost half a million within the next decade. For those who are just starting their exploration into the potential value of the cannabis plant we understand that it can be very confusing wading through all of the information on how to best put it to use.

One of the most frequent questions is how to figure out the difference between the cannabinoids, THC and CBD.

What are cannabinoids?

Basically, cannabinoids are chemical compounds produced by the cannabis flower that act on the cannabinoid receptors scattered throughout the body. These receptors are part of the larger endocannabinoid system, which works in the same way as your other systems (nervous, digestive, etc.) to manage processes in the body such as appetite, pain-sensation, mood and memory. When the endocannabinoid system is not working properly, the results are physical complications and illness. Cannabinoids such as THC and CBD help by mimicking your natural endocannabinoids, providing relief from the symptoms.

What is THC?

Also known as delta-9-tetrahydrocannabinol, THC is the principal psychoactive ingredient of cannabis, which means it is the cannabinoid responsible for the “high” or euphoria.

While studies to confirm the scope of its medical effectiveness are ongoing, both anecdotal and clinical evidence have shown THC to be helpful for:

  • Immune system regulation
  • Anti-inflammation
  • Pain relief
  • Increased mood
  • Euphoria stimulation
  • Appetite stimulation
  • Muscle relaxation
  • Reducing some types of epileptic seizure
  • Reducing nausea

Studies have found that THC reduces spasticity and spasms in patients with Multiple Sclerosis.

What is CBD?

Properly named as cannabidiol, CBD is the second most well-studied cannabinoid. One primary difference is that CBD is non-psychoactive, lacking the “high” patients experience when using THC.

Through both anecdotal and clinical evidence, CBD has gained in popularity as being used for:

  • Pain relief
  • Reducing nausea
  • Reducing anxiety
  • Controlling epilepsy
  • Immunosuppression
  • Muscle relaxation
  • As an anti-psychotic
  • Reducing inflammation
  • Reducing insomnia
  • Calming

Medicinal cannabis high in CBD and extremely low in THC has been used with children with varying disorders, particularly rare forms of epilepsy when all other treatment options have been explored.

Finding the right balance

While both THC and CBD are becoming a more popular option as a tool to help alleviate symptoms felt as a result of a number of medical conditions, the optimal dosing level of each is not known. Studies are ongoing to discover the full potential of both CBD and THC. By finding the right balance of the two a patient can achieve therapeutic treatment without experiencing an unwanted euphoria.

Yet finding the right balance of THC and CBD, determining whether inhalation of herbal cannabis through a vaporizer or ingesting cannabis oil, and setting the right dosage are frequently the biggest challenge a patient faces when they start to use medical cannabis. As a result, it can feel like a process of trial-and-error, working with a health care practitioner to determine the ideal combination to help a patient find relief.

Once a patient does find their “sweet spot” as it were, it can help return to them a quality of life they may have thought gone. Finding relief, with little to no side-effects is what draws most people to cannabis as a form of treatment, and what a relief it is!
