Medicinal CBD Oil May Help Improve Sleep in Adults
29/06/2025Sleep issues are a growing concern in Australia. Many are searching for natural, effective solutions beyond traditional sleeping pills. Medicinal CBD oil is emerging as a promising option, with research suggesting it may support better sleep and reduce anxiety. In this article, we’ll explore the science, benefits, legal status, and safe access to medicinal CBD oil in Australia.
Why Sleep Disorders Are on the Rise in Australia?
Sleep problems are more common than ever. Recent data from the Sleep Health Foundation and the Australian Institute of Health and Welfare (AIHW) show that up to 55% of Australians experience poor sleep or insomnia at some point. Chronic sleep deprivation affects concentration, memory, mood, and even the immune system. Poor sleep over time can take a serious toll, raising the risk of heart conditions, blood sugar issues, and emotional imbalance.
With growing concerns about the side effects of strong sleep medications, many Australians are choosing calmer, natural ways to improve their rest. This shift has sparked interest in medicinal CBD oil, which offers a non-sedative approach to sleep improvement. As more research emerges, CBD is gaining recognition as a potential alternative to over-the-counter sleep aids, especially for those seeking a plant-based solution.
What Is Medicinal CBD Oil and How Does It Work?
Medicinal CBD oil is a concentrated extract from the hemp or cannabis plant, containing cannabidiol (CBD) as its main active ingredient. Unlike THC (tetrahydrocannabinol), CBD is non-intoxicating and does not produce a “high.” Instead, it interacts with the body’s endocannabinoid system (ECS), a network of receptors (CB1 and CB2) that help regulate mood, sleep, pain, and immune function.
CBD appears to influence these receptors and may also affect serotonin signalling, which is crucial for mood and sleep regulation. By modulating the ECS and related pathways, medicinal CBD oil can help balance sleep-wake cycles, reduce anxiety, and support relaxation.

Beyond sleep, many Australians are using CBD for pain and inflammation. See our Best CBD Oil for Pain and Inflammation – 2025 Guide to explore top options.
Is Medical CBD Legal in Australia?
In Australia, medicinal CBD oil is legally available, but only through a doctor’s prescription. It’s regulated to ensure safe and proper use under medical care. The Therapeutic Goods Administration (TGA) regulates CBD as a Schedule 4 (prescription-only) medicine. While there has been talk of low-dose CBD becoming available “over the counter,” as of mid-2025, all CBD oil for therapeutic use still requires a doctor’s prescription in Australia, including in Victoria, Queensland, and the Sunshine Coast.

What Do Scientific Studies Say About CBD Oil and Sleep?
Key Clinical Trials and Meta-Analyses
Several recent studies have explored how medicinal CBD oil affects sleep:
| Study | Participants | Dosage | Result |
| Shannon et al. (2019) | 72 adults | 25–50mg | Improved sleep in 67% of participants |
| Bod Science Phase IIb Trial (2023) | 208 adults | 50 mg and 100 mg | 100 mg dose showed statistically significant improvement in insomnia severity index scores (per protocol group) |
| Narayan et al. (2024) | 30 adults | 150 mg nightly | No significant difference in sleep onset latency but improved sleep efficiency and well-being scores |
| Medicinal Cannabis Study (2022) | 29 Adults with insomnia | Variable (CBD oil) | Well tolerated and effective in improving sleep quality |
The 2019 Permanente Journal study found that two-thirds of adults using CBD reported better sleep in the first month. These studies suggest a dose-response relationship: lower doses of CBD may help promote wakefulness, while higher doses are more likely to aid sleep.

How Does Medicinal CBD Oil Affect Sleep Architecture?
A 2023 double-blind, placebo-controlled study found that a full-spectrum medicinal cannabis oil containing CBD significantly improved sleep in adults with insomnia. Participants reported faster sleep onset, better sleep quality, and less waking during the night Meanwhile, a 2018 research study in 27 healthy volunteers found no significant changes in sleep stages, total sleep time, or sleep quality after a single 300 mg dose of pure CBD, indicating it did not alter normal sleep architecture.
How Australians Access Medicinal CBD Oil for Sleep
Can You Get CBD Oil Over the Counter in Australia?
As of 2025, you still cannot buy medicinal CBD oil over the counter in Australian pharmacies. In 2020, the Therapeutic Goods Administration (TGA) down-scheduled certain low-dose CBD products (≤150 mg/day) to Schedule 3—meaning they could be sold by pharmacists without a prescription. However, no products have been approved for over-the-counter sale because none have been listed on the Australian Register of Therapeutic Goods (ARTG).
Despite regulatory progress, all medicinal CBD oil in Australia still requires a prescription from a GP or through an Authorised Prescriber program.

How to Get a CBD Oil Prescription in Australia?
To legally access medicinal CBD oil in Australia, follow these steps:
- Consult Your GP: Book an appointment with a doctor who is familiar with medicinal cannabis. Not all GPs prescribe CBD, so look for clinics or practitioners with experience in this area.
- Special Access Scheme (SAS-B): If your doctor thinks CBD oil could help, they will apply through the TGA’s Special Access Scheme (SAS-B) or become an Authorised Prescriber.
- Prescription and Dispensing: Once approved, you’ll receive a prescription, and you can fill it at a licensed pharmacy or through an approved online supplier.
Benefits of Medicinal CBD Oil for Sleep vs Traditional Sleep Aids (Backed by Studies)
- Improves sleep onset and quality
A 2019 clinical case series of 72 adults reported that 66.7% experienced improved sleep scores within the first month of daily CBD use. - Enhances deep and REM sleep
A 2023 pilot trial found that a CBD and terpene blend increased restorative sleep, including slow-wave and REM sleep, in adults with insomnia. - Does not cause next-day grogginess
A 2023 randomised controlled trial comparing CBD and melatonin found that 15 mg CBD improved sleep quality without the hangover effect often linked to other aids. - Non-habit forming and safe for long-term use
Across these studies, CBD was well tolerated, with no signs of dependence or withdrawal, even with continued use over several weeks.
Unlike many prescription sleeping pills, medicinal CBD oil does not suppress REM sleep or cause next-day drowsiness. It’s also non-addictive, making it a safer long-term option for many.

Common Side Effects in Australia
CBD is generally well-tolerated, but side effects can occur, especially at higher doses or when combined with other medications.
| Side Effect | Frequency | Study Support |
| Fatigue | Occasional | A 2017 review found fatigue as a common dose-dependent side effect |
| Drug Resistance | Rare | CBD can inhibit cytochrome P450 enzymes, affecting other drugs. |
| Diarrhoea | Rare | Noted in epilepsy trials using Epidiolex (CBD isolate). |
Always speak to your doctor about potential interactions, especially if you take other medications.

Can You Use Medicinal CBD Oil Every Night? What Experts Say
A 2024 randomised, double-blind trial (n=30) tested nightly sublingual 150 mg CBD in adults with primary insomnia over two weeks. Results showed no impairment in daytime cognitive function, while participants reported greater calmness, clear-headedness, and coordination. Some experienced mild dry mouth, but overall the study concluded nightly use was safe and well-tolerated in insomnia sufferers. Always follow your doctor’s advice and start with the lowest effective dose.
