Medicinal cannabis products can be taken in several ways, including:
swallowing oils, liquid capsules or tablets
spraying into the mouth or under the tongue
heating the cannabis and inhaling the vapour (vaporising).
The concentration of THC and/or CBD in cannabis oil is measured in milligrams per millilitre (mg/ml) of oil.  Medicinal cannabis is prescribed in various dosages depending on the patient’s medical condition.  Always speak to your doctor for advice about how much and how often you should be taking your prescribed medicine.
