What is it?
- Cannabis is a greenish or brownish material consisting of the dried flowering, fruiting tops and leaves of the cannabis plant Cannabis Sativa.
- Hashish or cannabis resin is the dried brown or black resinous secretion coating the flowering tops of the cannabis plant.
- Cannabis is known by many names including marijuana, weed, hash—and others.
- Cannabis is most often smoked in a “joint.” It is also smoked in a water pipe or “bong,” where the smoke is drawn through water to cool it and lter out small particles before inhaling. It can also be vaporized in an e-cigarette or consumed in edible products.
- Currently in Canada, licensed producers and registered individuals can supply cannabis for medical purposes in fresh, dried and oil forms (Health Canada, 2016).
