What is cannabis?

  • Cannabis is a plant with psychoactive properties that produces dried flowers, fruiting tops or leaves of the cannabis sativa or indica plants or a mixture of the two called hybrids (CCSA).
  • Cannabis can be refined to other forms such as oils, extracts or resins.
  • Cannabis goes by many names including weed, marijuana, hash, pot, ganja, bud, etc. 

After alcohol, cannabis is the most widely used psychoactive substance in Canada.

Definition: THC

  • THC is one of the chemical compounds in cannabis that is responsible for how your brain and body respond to cannabis. It’s the mind-altering chemical that provides the feeling of being “high” to the user. The concentration or strength of the cannabis is usually shown as a percentage of THC by weight (or volume in oil). Products high in THC are more likely to result in harm. Choose lower THC products to reduce your risks.


Definition: CBD

  • CBD is another chemical compound found in cannabis. It has no mind-altering effects and may, in fact, block or lower some of the effects of THC on the mind. Choose products with a higher CBD to THC ratio to reduce your risks. 

Converting Potency from Mg/g to %

The conversion method from mg/g to % is easy: Move the decimal point one spot to the left to figure out the percentage of THC or CBD. 

For example, if the flower is listed as 192 mg/g of total THC, then it contains 19.2% THC.

You must use the total THC as listed on the package for this conversion.

Here are some common potencies in both mg/g and their % equivalent:
