Cannabis 101

The Plant

Leaves from the plant are symmetrical and are generally made up of five or seven leaflets. The flowering tops and upper leaves are covered in a sticky resin and the plant’s main active chemical is THC (delta-9 tetrahydrocannabinol). The commonly recognizable fan leaves help distinguish between indica and sativa marijuana plants. Darker, wide leaves for Indica and lighter green, lean slender fingers for Sativa is the norm.


The various strains of cannabis possess particular properties resulting in different effects. Cannabidiol (CBD) and tetrahydrocannabinol (THC) are two natural compounds found in the plants. Even though they have similar chemical structures, they don’t have the same psychoactive effects. The cannabis plant happens to be one of the most pharmacologically active plants on the planet, containing over 400 active chemicals. The unique, active components of cannabis are called cannabinoids, which are found alongside active chemicals called terpenoids, known for their aromatic qualities and flavonoids which are antioxidants.


CBD is a non-psychoactive compound. That means it doesn’t produce the “high” associated with THC. CBD is found mostly in extractions from the hemp plant. It’s sold in gels, gummies, oils, supplements, extracts, and more. CBD binds very weakly, if at all, to CB1 receptors in the brain.

Mood Boost


THC is the main psychoactive compound in marijuana that gives the “high” sensation. It can be consumed by smoking marijuana. It’s also available in oils, edibles, tinctures, capsules, and more. THC binds with the cannabinoid 1 (CB1) receptors in the brain.



The strains, the way you choose to consume the product, and your own unique individuality will make a difference in your cannabis experience and the effects it produces for you. The effects can range from relaxing or calming to uplifting and invigorating. Mood can also affect how you enjoy your cannabis product and the resulting effects.


Typically cannabis features notes of pine, citrus, fruit, and spice scents. Cannabis can be aged to produce more distinct aromas. If you’re attempting to discern the aromas of different strains, start with the one with the lowest amount of THC, so you won’t be overwhelmed. Essentially, what you smell from your cannabis depends on storage, personal preferences, sense of smell, and mood.


Many factors affect the cannabis density. Lighting, lighting colour, temperature, humidity, nutrition and watering all play a role. Producing dense, resin covered buds is a cannabis producer’s ultimate goal. Indicas are compact and stocky, with dense, heavy buds. Sativa buds tend grow larger than Indica, but, they will usually weigh less than Indica when dry, due to their lower density.


Chlorophyll represents about 70% of the pigments in plants. It is the reason why the plant is predominantly green. We usually associate cannabis with being only green, but in reality, strains such as Critical Kush, Grape Ape, Panama Red, and Serious Six consist of many colours including pink, purple, blue, red, and orange. Darker colour for Indica, and lighter green for Sativa, is a rule of thumb.

Types of Strains

The main two plant varieties are Cannabis Sativa and Cannabis Indica. Hybrid strains contain a mix of Sativa and Indica genetics and, depending on their makeup, can take on characteristics from both strains.


“Indica” has come to describe stout, broad-leaf plants, thought to deliver sedating effects. It has a shorter flowering cycle and is better suited to growing in cooler climates with a shorter season.
Sleepy / Mellow / Calm
Night Use


Hybrid refers to plants that possess the genetics of both Sativa and Indica strains. Its characteristics can vary depending on the mix of the genetic features.
Indica & Sativa Qualities
Night /Day use


“Sativa” refers to tall, narrow-leaf varieties of cannabis, thought to induce energizing effects. It has a longer flowering cycle and is better suited to growing in warmer climates with a longer season.
Stimulating / Sociable / Cheerful
Day Use

Ways to Consume

Just like the varieties in cannabis itself, there is more than one way to experience and enjoy your cannabis products.


There are currently two main inhalation methods: smoking and vaporization. The ancient method of inhaling cannabis product is the one most commonly associated with experiencing the product. Fortunately, cannabis smokers have a wide array of devices available to them.


Oil Extracts

Unprocessed, cannabis oils contain the same active ingredients as the plants. In commercially-produced oils, the concentrations of CBD and THC tend to be well-controlled, making it easy to calculate doses. Oils can be taken orally, added to tinctures, used in baked goods or added to topicals.



Concentrates are products made from the plant that have been processed to keep only the most desirable plant compounds (primarily the cannabinoids and terpenes). Ounce for ounce, cannabis concentrates have a greater proportion of cannabinoids and terpenes when compared to natural cannabis flowers.


Also known as hashish, it's made by eliminating plant material and collecting the trichomes from the flower tops of female plants. The THC content varies from 20 to 60%. Traditionally, hash has been consumed orally, either as a solid or infused into a beverage. Some hashish has the ability to be melted by vaporizing on a hot surface. This is known as "dabbing."


Rosin refers to an extraction process that utilizes a combination of heat and pressure to squeeze resinous sap from the original material. With cannabis, this is incredibly versatile in that it can either be used with flowers or to clean up hash into a full-melt hash oil. This process does not use solvents unlike "shatter."


“Shatter” is usually made by using butane as the solvent, and its more technical name is Butane Hash Oil, or BHO, for short. Another popular type of solvent extract is CO2 oil, used in most vape pen cartridges. In the case of cannabis concentrates, other types of solvents, like alcohol or propane can be used to extract cannabinoids.


It’s the purest cannabis concentrate available. Distilled cannabis has the highest THC content of any available concentrate. Not only do distillates’ high THC content level require small doses to experience its effects, its nose-discreet characteristics, as in being odourless, makes it ideal to consume publicly.
