What is CBD Oil? Benefits, Uses & Legality in NZ

CBD oil is gaining widespread popularity in New Zealand as more people turn to plant-based alternatives to support their health. But what exactly is CBD oil, how does it work, and is it legal?

Here’s a quick summary:

• CBD is a non-intoxicating compound from the cannabis plant¹
  
• It’s legal by prescription only in New Zealand
  
• It may support relief from pain, anxiety, sleep issues, and inflammation¹
  
• It comes in different forms, including full-spectrum, broad-spectrum, and isolates

This guide covers everything you need to know about CBD oil, from how it works to how to access it safely and legally.

Understanding CBD and THC

CBD (cannabidiol) and THC (tetrahydrocannabinol) are two of the most well-known compounds found in the cannabis plant. While they share a similar chemical structure, their effects are very different.

CBD is non-psychoactive, meaning it does not cause a “high.” It may support pain relief, reduce anxiety, and aid sleep and inflammation¹.

THC is the main psychoactive compound in cannabis and is responsible for the euphoric or intoxicating effects often associated with recreational use.

CBD may also help counteract some of the unwanted side effects of THC, such as anxiety or paranoia².

How CBD Oil Works

CBD interacts with your body’s endocannabinoid system (ECS) – a network of receptors and enzymes that helps regulate functions like mood, pain, sleep, and immune response. By influencing this system, CBD may support balance and help naturally reduce unwanted symptoms³.

Is CBD Oil Legal in NZ?

CBD oil is legal in New Zealand with a valid prescription. Any registered doctor can prescribe it, provided it’s clinically appropriate for your condition. These products must meet strict quality standards under New Zealand’s Medicinal Cannabis Scheme.

Recreational cannabis remains illegal. THC-containing products can also be prescribed, but are more tightly regulated under the Misuse of Drugs Act 1975.

Always carry your prescription or treatment plan when using medicinal cannabis products to ensure you can prove your legal right to possess and use them.

Differences Between Hemp Oil, CBD Oil, and Cannabis Oil

• Hemp Oil: Extracted from hemp seeds. Nutrient-rich but contains almost no CBD or THC.
  
• CBD Oil: Extracted from the cannabis plant’s leaves and flowers. Used for therapeutic purposes.
  
• Cannabis Oil: A broad term that can refer to oils containing CBD, THC, or both.

Understanding Full-Spectrum CBD Oil

Full-spectrum CBD oil contains a wide range of cannabinoids (including trace amounts of THC), terpenes, and flavonoids. These compounds may work better together through what’s known as the “entourage effect”⁴.

Other types include:

• Broad-spectrum CBD – similar to full-spectrum, in that it contains a wide range of cannabinoids, but without the THC
  
• CBD isolate – purified CBD, with no other plant compounds or cannabinoids
  

If you’re subject to drug testing, THC-free options like isolate or broad-spectrum are recommended⁷.

Potential Benefits of CBD Oil

CBD oil is being studied for its possible benefits across a wide range of health concerns:

• Pain relief – May reduce discomfort from arthritis, fibromyalgia, or injury¹
  
• Mental wellbeing – Could support people managing anxiety, stress, or PTSD⁵
  
• Better sleep – May help regulate sleep cycles for those with insomnia⁵
  
• Gut health – Anti-inflammatory effects may support those with IBD or IBS
  
• Neurological support – Being studied in conditions like epilepsy, MS, and Parkinson’s⁵
  
• Cancer treatment side effects – May assist with nausea, appetite, and pain
  

Always consult your doctor to see if CBD is suitable for your needs.

Potential Side Effects and Risks

CBD is generally well tolerated, but side effects may include:

• Drowsiness or fatigue⁶
  
• Dry mouth
  
• Diarrhoea
  
• Dizziness
  
• Interaction with some medications⁶
  

If you have liver issues or take medications like clobazam, phenytoin, warfarin, or some other medications, you must consult your doctor before using CBD oil⁶.

Interactions with Other Medications

CBD can interact with enzymes in the liver that metabolise many prescription drugs. These interactions can increase or decrease how your medications work⁶, so it’s important to speak to a healthcare professional before starting CBD.

CBD Oil Dosage

Dosage depends on:

• Your medical condition
  
• Weight
  
• Sensitivity to cannabinoids
  
• The product’s concentration
  

Most people begin with a low dose (around 25mg per day) and increase slowly under guidance. Some people may need over 100mg per day, but this varies greatly.

The Cost of CBD Oil in NZ

CBD oil typically costs between $2 and $5 per day, depending on the dose and product. Your doctor can help you choose the most cost-effective option for your needs.

Obtaining a CBD Oil Prescription in NZ

You can get a prescription for CBD from any registered doctor in New Zealand, including:

• Your GP
  
• A doctor at Cannabis Clinic
  

If your GP isn’t familiar with prescribing CBD, you can book an appointment with one of our experienced cannabis doctors.

CBD Oil for Pets in NZ

At this stage, no CBD oil products have been approved for veterinary use in New Zealand. Speak to your vet if you have questions about treatment options for your pet.

Does CBD Oil Show in a Drug Test?

CBD is not screened for in standard drug tests. However, full-spectrum CBD products may contain small amounts of THC that could lead to a positive result⁷. If you are drug tested, we recommend using THC-free products only.

CBD and Driving in New Zealand

CBD is legal, but it’s important to avoid driving if you feel drowsy or unwell. The Land Transport Act prohibits driving while impaired by any drug, including prescription medicines. Always monitor your reaction before getting behind the wheel.

Travelling Overseas with CBD Oil

Before flying with CBD oil:

• Carry your prescription and treatment plan
  
• Research destination country laws
  
• Store in your carry-on in original packaging
  

Not all countries permit CBD products – always check local laws before you travel.

Final Thoughts

CBD oil offers a promising natural treatment option for a wide range of conditions. With a prescription from a qualified doctor, you can access high-quality, legal CBD products tailored to your needs.
