CBD Oil Dosage

Treatment with medicinal cannabis is a very personal and every patient who has been prescribed and approved to use medical cannabis will respond differently. That is why it’s important to discuss dosing in conjunction with a GP or cannabis doctor. The amount of CBD oil a patient should take depends on a range of factors, including:

  • Body weight
  • Existing conditions
  • The endocannabinoid system
  • The amount of CBD in each drop, powder, pill or capsule

There’s a lot of variables when finding the correct dosage for CBD oil and CBD products. Cannabis doctors and GPs should aim to help their patients in understanding the prescribed product, the pathways to approval in Australia, the appropriate dosages and potential side effects. This is especially important if a patient is taking other medicines that can interact with CBD.


Titration is a common term when treating with medical cannabis oil. It refers to the process of adjusting the dosage and aiming to find the optimal amount.

For this, it’s important to keep track of how much CBD is being administered and the results. Keeping track of sleeping, feelings and how long the effect lasts is an essential part of the dosing process.

There is a myth that exists that a big dose is necessary to relieve symptoms faster. This is simply not true. When it comes to medical cannabis products, it is recommend to ‘start low and go slow.’ Slowly titrating medicine until finding the minimal effective dose can give doctors and their patients a better understanding of how CBD oil products can affect them.


Consuming CBD Oil

Consumption of CBD oil

The three steps for eligible patients are:

  1. Start by eating something with fat in it (i.e. spoonful of yogurt, cheese & coconut oil, avocado etc.)
  2. Place drop/mL(s) on a spoon, then underneath the tongue and swallow after 90 seconds
  3. Record in a dosing diary

How long does CBD oil take to work?

When ingesting medical cannabis, it’s important to start low and go slow, because the effects of the CBD oil can be a lot stronger and can last a lot longer than when inhaled.

Once ingested, it can take up to 90 minutes to absorb the active ingredients with a longer effect lasting between 4-8 hours.

Determining dosage

Determining the optimum personalised dose of CBD oil may take a few weeks to achieve. Eligible patients who follow the dosing plan suggested by their doctor or nurse and record every dose in a dosing diary, will eventually be able to find an individualised optimal dose.

Possible Side Effects of CBD

CBD has a narrow side effect profile. Potential side effects of cannabidiol include dry mouth, low blood pressure, light-headedness, diarrhoea, and drowsiness, however, these are very uncommon.

Medicinal cannabis is a very personalised medicine and for the highest quality of care and assurance, it’s important to conduct treatment with a cannabis doctor or trusted GP.
