As of October 17th 2018, the ACMPR is now consolidated as part of the Cannabis Regulations

The Access to Cannabis for Medical Purposes (ACMPR) are the Government of Canada's regulations that enable patients to obtain authorization to access cannabis for medical purposes.

It's a mail order system that allows patients to sign up with a licensed producer, and legally purchase medical cannabis online in Canada.

Under the ACMPR, Doctors or Nurse Practitioners are responsible for authorizing patient access to medical cannabis.

Cannabinoids are the active compounds found within Cannabis. There are at least 100 different cannabinoids that we know about, with THC and CBD being the ones with the relatively highest concentration in the plant.

THC and CBD are both cannabinoids found in cannabis.

Indica and sativa are considered to be a species of the genus Cannabis. However, it’s relatively rare to find either a pure Sativa or a pure Indica strain, as most cultivated strains of cannabis today are a hybrid of the two, being either indica or sativa dominant.


As more scientists study this plant, we’re learning that the classification of cannabis into Indica, Sativa, and Hybrid is incredibly oversimplified, and the subject of intense debate. The cannabis plant contains a huge array of cannabinoids, terpenes, and flavonoids, all of which interact with your body’s biochemistry in a very unique way. This means that you may have a totally different reaction to one strain, then say, the next person.


We’ve found that a better way to classify cannabis is to go by the ratio of THC to CBD. That’s why you’ll see all of our strains in three different categories, THC dominant, CBD dominant, or a balanced ratio.

Terpenes are the fragrant compounds that give cannabis it’s aromatic diversity. Found throughout the natural world, terpenes and can be found in many other plants, herbs and fruits. This is why certain strains will have the familiar notes of citrus, blueberry, pine, hops, etc. 

THC is the most prominent active compound within cannabis, and is attributed to producing most of the psychoactive effects.

CBD is the second most prominent cannabinoid found in cannabis, and is generally considered non-psychoactive, or less psychoactive than THC rich cannabis.
