What does T and C numbers stand for?
T and C numbers: As in T22 or T10:C10
In a prescription name, T stands for THC and C for CBD, and the number is the labelled strength. For flower it is a percentage: T22 is about 22% THC. For oils and cartridges it is milligrams in each millilitre or gram: T10:C10 is about 10 of each. For pastilles it is milligrams in each one. The label allows a range either side, which the product page shows.
