Cannabis product label

Just like any other prescription medication in Australia, understanding the information on a medical cannabis product label is essential for both doctors and pharmacists to prescribe and dispense this medicine.

Labels on medical products provide consumers with the necessary information on what the product is, what it is used for, how to use it, how to store it and any hazards associated with it.

With more medicinal cannabis products hitting the Australian market and more doctors prescribing this therapy to their patients every year, understanding how to read a cannabis label is important.

If you’re a health professional in Australia, read this blog to understand the key elements of cannabis supplier and dispensing labels and what you need to look for on these products.

What to look for on a cannabis supplier label?

Patient reading cannabis label

A cannabis supplier label refers to the packaging label the product comes in. These labels are manufactured by the product supplier and are placed on the products before they arrive at the pharmacy. There are a few elements of a medical cannabis product label that are important for patients, pharmacists and doctors to recognise, including:

Product & Supplier Information

Every medicinal cannabis product is required to have a product name and the batch number on the label. This will help pharmacists and doctors easily distinguish between each product.

Medicinal cannabis product labels must also include information about the manufacturer/supplier to signify which company manufactured the product.

This information includes:

Supplier name and contact information

Product Dosage Form

The dosage form refers to the physical form the product comes in (e.g. oral liquid, dried herb etc.). As cannabis is a highly personalised medicine, different product formulations can be suitable for eligible patients with different circumstances.

The main dosage forms medical cannabis is manufactured in include:

  • Capsule
  • Herb (Dried)
  • Inhalation Pressurised (Metered Dose Preparation)
  • Oil
  • Oral Liquid
  • Pastille
  • Tablet (Chewable)
  • Topical

Total Cannabinoid Content

One of the most important things to recognise on a cannabis label is the cannabinoid content, otherwise known as the active ingredients.

Cannabidiol (CBD) and Delta-9-tetrahydrocannabinol (THC) are the two primary cannabinoids present in the cannabis plant, which are responsible for the main effects cannabis produces in the body.

The total content of these cannabinoids must be clearly displayed on the label. Here’s an example of how it can be displayed on labels:

25mg/ml CBD (total Cannabidiol)
<25mg/ml THC (total Delta-9-tetrahydrocannabinol)

What is the THC : CBD ratio?

The THC:CBD ratio is a critical element of a medicinal cannabis label that indicates the amount of THC compared to the amount of CBD in each dose.

As cannabis can produce different effects depending on the different levels of active ingredients, doctors will prescribe products with various ratios depending on what’s most suitable for each patient’s chronic condition.

To give you a better idea, a ratio of 1:1 would mean there is the same amount of THC and CBD in each dose. Whereas a THC:CBD ratio of 20:1 would mean there is 20 times more THC in each dose, compared to CBD. Some labels may also include the THC:CBD content per container (e.g. 1000MG : 250MG).

In the example above, the ratio is 5:20, which equates to 5mg/ml of THC and 20mg/ml of CBD in the product.

Generally, the concentration should note the dominant cannabinoid of THC first and CBD to follow (THC : CBD). If you are unsure, we recommend checking with the wholesaler or prescribing doctor to ensure the label information accurately matches what has been prescribed.


Product Weight

Usually displayed in either grams or millilitres, the product’s total weight must be visible on the product. This can usually be found in the product name (e.g. Brand name | THC : CBD Ratio | Weight).

As cannabis comes in a range of different dosage forms such as flower, oil or oral liquid, the total weight can be displayed differently, depending on each product. Here are some examples:

  • Milligrams of cannabinoid per gram or mg/g or mg/unit (flower, soft gels)
  • Milligrams of cannabinoid per millilitre or mg/ml (cannabis oils)
  • Milligrams or mg/unit of cannabinoid (edibles)
  • Percentage of cannabinoid in relation to total weight of product (flower)

Other Information

Medicinal cannabis labels contain a lot of the standard elements of any other prescription product such as packing and expiry dates, storage information and any relevant health warnings.


What to look for on a cannabis dispensing label?

Once a cannabis prescription is ready to be filled, the dispensing pharmacy will place a prescription label on the product. This label must include all the standard details included on a dispensing label for any pharmaceutical product.

The following information must be included on any dispensing label:

  • Patient’s name
  • Name of drug
  • Dosing instructions
  • Prescribing doctor
  • Prescription number
  • Dosing information
  • Dispensing pharmacy
  • Prescribing doctor
  • Warning label: Keep out of reach of children

When applying the dispensing label to the product, pharmacists must ensure it is not covering the batch number or expiry date.

Pharmacist checking cannabis label

For a pharmacist to dispense a controlled substance such as medicinal cannabis, the prescription must include specific information to be considered valid:

  • Date of issue
  • Patient’s name and address
  • Patient’s date of birth
  • Clinician name, address and DEA number
  • Drug name
  • Drug strength
  • Dosage form
  • Quantity prescribed
  • Directions for use
  • Number of refills
  • Signature of prescriber
