Cannabinoids

a glossary of common cannabinoids

CANNABINOIDS DESCRIPTIONS MOLECULE
THC Tetrahydrocannabinol Found in most strains of Cannabis, Tetrahydrocannabinol is responsible for the psychoactive effects of the plant. THC interacts with the cannabinoid receptor 1 and mimics our bodies own endocannabinoids, to create these effects. The CB1 receptor is involved in the body's control of many physiological and psychological processes such as appetite, sleep, memory, mood and more.
CBD Cannabidiol Cannabidiol is a non-psychoactive cannabinoid that interacts with many different receptors in the endocannabinoid system. CBD modulates the activity of THC, which can help reduce some side effects of THC.
CBG Cannabigerol CBG is the precursor to both THC and CBD, CBG is a non-psychoactive cannabinoid.
CBC Cannabichromene CBC is a non psychoactive cannabinoid commonly found in cannabis.
THCV Tetrahydrocannabivarin THCV is a psychoactive cannabinoid, similar to THC, that is present in many strains in small quantities.
CBDV Cannabidivarin CBDV is non-psychoactive cannabinoid very similar in structure to CBD. It is found in high quantities in strains derived from northern India and Nepal.
THCA Tetrahydrocannabinolic acid Tetrahydrocannabinolic acid, is a non-psychoactive cannabinoid found in raw and live cannabis. As the plant dries, THCA slowly converts to THC, this process can be expedited by Decarboxylation.

What are terpenes?

Terpenes are a large group of organic compounds created by plants. Many of these compounds are aromatic and contribute to the distinctive smell of cannabis. Terpene content can vary greatly between strains, giving each variety a unique taste and scent profile. The effects of each strain can also be attributed to differences in terpene and cannabinoid content.

As well as Cannabis, it is worth noting that many other herbs, flowers and essential oils derive their distinctive taste and scent properties from terpenes.

What is decarboxylation and why is it important?

Decarboxylation is the process of activating Cannabinoids in cannabis.

All Cannabinoids found within raw cannabis flowers exist in their acidic form with an extra carboxyl group attached to their chemical structure. This means that Tetrahydrocannabinol (THC) exists in its acidic form Tetrahydrocannabinolic acid (THCa), and Cannabidiol (CBD) exists as Cannabidiolic acid (CBDa).

To activate THCa into THC and CBDa into CBD, a chemical reaction known as decarboxylation is performed.  Decarboxylation is a chemical reaction whereby a carboxyl group is removed from the compound with heat and is released as carbon dioxide (C02).

What is the Equivalency Factor?

An equivalency factor is a way to equate the amount of dried cannabis flower (prescribed in grams) to a volume of cannabis oil (measured in milliliters). Each Licensed Producer is required by Health Canada to set an equivalency factor that makes it possible for physicians and patients to relate an amount of cannabis oil to dried product.

What is Whistler Medical Marijuana Corps Equivalency Factor?

WMMC has set an equivalency factor of 20% as a baseline to represent the total cannabinoid amount in dried cannabis. What this means is that the total amount of fully decarboxylated THC and CBD in our oils is compared to 1g of dried cannabis with the same ratio of THC/CBD.

What different equivalencies mean for ordering

Equivalency Factor Reduction To Possession Limit
30ml bottle of oil 60ml bottle of oil
6ml = 1 gram of dried cannabis - 5 grams - 10 grams
8ml = 1 gram of dried cannabis - 3.75 grams - 7.5 grams
12ml = 1 gram of dried cannabis - 2.5 grams - 5 grams

Clients can order more cannabis oil with the equivalency of 12 ml, because it takes less away from their possession limit during the 30 day ordering cycle.

Remember, equivalency factor is not related to dosage. The lower the equivalency factor the more concentrated the product, therefore more care must be taken when dosing.
