Methods of Use

There are differences between ingestion and inhalation. Often patients will benefit from more than one type of product to address different therapeutic needs. The route of administration will depend on your healthcare practitioner’s recommendation, as well as the availability of product through the licensed producer. The information below provides an overview of the different methods of use, which may serve useful as you begin or adjust your medical cannabis treatment.

Oil vs. Dried

Ingestible cannabis oil products (oil drops and softgels) are ready to consume in the sense that they do not need to be heated (activated) for the full effects to occur (potential). Consumers may take these products orally and will start to feel the effects within 1-4 hours (onset). The effects can last 6-12 hours (duration).

Dried cannabis (whole bud, pre-rolls, shake and trim) requires heat (activation) for the full effects to occur (potential). This can be achieved by vaporizing or smoking for example. Inhaling the vapour will cause the consumer to feel the effects within 0-0.5 hours (onset). The effects can last up to 6 hours (duration).

Metabolism of cannabis



The most commonly known of all 85+ cannabinoids produced by the cannabis plant is delta-9 tetrahydrocannabinol - or THC. This is the compound that is associated with the euphoria, or psychoactive high found with some strains of cannabis. THC provides more than a euphoria; it also has many medicinal uses. THC can act as an effective analgesic or pain reliever, and provides the most benefit when used proactively before the pain sets in. THC is also known to relieve nausea, poor appetite, headaches, as well as reduce the intraocular pressure in glaucoma and regulate mood, depending on the strain and your biology.


Cannabidiol, more often referred to as CBD, is the second most recognized cannabinoid in cannabis after THC. Unlike THC, CBD produces virtually no psychoactive effect. Research increasingly shows that CBD may offer anti-epileptic, anti-inflammatory, and anti-anxiety effects to patients. CBD may also demonstrate neuro-protective capacities; allowing it to protect against neuronal injury or degradation found in disorders such as a stroke, or neurodegenerative diseases such as Alzheimer’s, Parkinson’s, or multiple sclerosis. It is due to these benefits that many consider CBD to be the most relevant with respect to the medicinal properties of cannabis.
