Not with a guarantee. The closest Australian category to “no THC” is a prescribed CBD-only product. In law, a CBD-only product is one where CBD makes up 98% or more of the cannabinoids, but up to 2% can be other cannabinoids, which can include a small amount of THC.1 So even a CBD-only product is not guaranteed to be THC-free.
What is a CBD-only product?
The Therapeutic Goods Administration (TGA) sorts prescribed cannabis medicines into five categories by how much of the cannabinoid content is CBD.23
| Category | Name | CBD share of cannabinoids | Schedule |
|---|---|---|---|
| 1 | CBD medicinal cannabis product | 98% or more | 4 |
| 2 | CBD-dominant | 60% to under 98% | 8 |
| 3 | Balanced | 40% to under 60% | 8 |
| 4 and 5 | THC or other cannabinoid dominant | Under 40% | 8 |
Only Category 1 is “CBD-only” in the legal sense. A “CBD-dominant” oil is a Schedule 8 controlled drug and can contain a meaningful amount of THC.2
Can a CBD-only product still contain THC?
Yes. A Victorian Government fact sheet warns that some medicines “that contain mostly CBD may also contain very small amounts of THC”.4 Under the Australian quality standard, THC must be declared as an active ingredient once it reaches 1.0% of the product. Below that, it may be present without appearing on the label.5 So “no THC listed” is not the same as “no THC”.
An isolate (CBD on its own) is designed to have no THC. In a study of oral and vaporised pure CBD, only 1 of 218 urine samples screened positive at the lowest cut-off, and none was confirmed.6
Will I be offered a CBD-only product?
Not necessarily. Most cannabis prescribing in Australia involves THC. 85% of units sold in the first half of 2025 were products in the category with almost no CBD.3 CBD-only oral liquids made up 29,165 of the 177,762 Special Access Scheme approvals in 2024.78
What should you ask?
- Which TGA category is this product, and is it Schedule 4 or Schedule 8?
- How much THC does it contain per millilitre?
- Could it affect a roadside, workplace or sporting drug test?
These answers matter for driving and drug tests. The prescriber decides whether any product is appropriate for you.
