Cannabis is classified as a cannabinoid drug. The exact number of different cannabinoids in the cannabis sativa plant is still being researched, but it primarily contains the psychoactive cannabinoid THC (delta9 tetrahydrocannabinol) and the non-psychoactive cannabidiol (CBD).

Cannabis Variants

Known Variants

Marijuana – the dried leaves and flowers (buds) of the cannabis plant that are smoked in a joint or a bong. This is the most common form.

Hashish – the dried plant resin that is usually mixed with tobacco and smoked or added to foods and baked; such as cookies and brownies.

Hash oil – liquid that is usually used sparingly (due to high potency) and added to the tip of a joint or cigarette and smoked.

Concentrates – extracts (dabs, wax or shatter) typically using butane hash oil as a solvent, often vaporized in small quantities due to high THC content.


Cannabis can be prepared into various foods generally called ‘edibles’. It takes between 1-3 hours to feel the effects after eating cannabis. Impatient or naïve users may believe they have not taken enough to feel the effects, and if they consume more they may find later that the psychoactive effects are unpleasantly strong.

When edible products have inconsistent levels of THC even experienced users may find it difficult to regulate the amount consumed. When smoked or vaporized, the effects are usually felt straight away. There are health concerns about the impact of smoking, especially in the long term and if mixed with tobacco.

The effects of cannabis vary between people, and may even be different for the same person at different times. Some people report feelings of relaxation and euphoria while other people report experiences of anxiety and paranoia.
