NSW Cannabis Medicines Advisory Service


The NSW Government-funded NSW Cannabis Medicines Advisory Service (CMAS) provides free clinical guidance and advice to NSW medical practitioners considering prescribing a cannabis medicine for their patient.

CMAS can provide:

  • Information about cannabis medicines (e.g. formulations, dosing, potential drug interactions).
  • Advice tailored to patient-specific clinical context.
  • Current scientific evidence, to support applications for authority to prescribe.
  • Guidance and tools for monitoring potential therapeutic and adverse effects.
  • Information on open clinical trials using cannabis medicines.

CMAS was launched in January 2018 and is headquartered in Newcastle within Hunter New England Health. This ensures access to expert clinical advice for both metropolitan and regional practitioners, including those based in rural and remote areas. It is staffed by senior pharmacists, a clinical pharmacologist and an administration officer.

Who can contact CMAS 

Any medical practitioner in NSW can contact CMAS, as well as other health professionals and services, including pharmacists, nurses, pain clinics and clinical trials.

CMAS provides support for:

  • NSW heath professionals; and
  • NSW health professionals who are treating a patient in a cross-border area of NSW; and 
  • Health professionals in a state or territory outside of NSW who are treating a patient residing in NSW.
