Clinical decision support · for registered healthcare professionals

The kinetics behind every cannabinoid interaction.

Cannanetic resolves CYP, CES, and UGT-mediated interactions between cannabinoids and medications, and shows where published in vitro inhibition may become relevant. Every Ki is traced to its source. The range is not a dose.

Medicinal cannabis, explained for clinic

Cannanetic is built for registered healthcare professionals. The pages below are a briefing on the plant, the evidence, and Australian access law — written for clinicians and pharmacists who have not prescribed or dispensed these products before. Clinical tools stay behind sign-in and do not collect patient data.

Questions clinicians actually ask

Short answers for practitioners who have not worked with medicinal cannabis before. Each statement is cited. Rules below are as at September 2026 — follow the linked official page if it has moved.

Full briefing

What is the difference between S4 CBD and S8 products?

Products that are almost entirely CBD can sit in Schedule 4. Products that contain THC are typically Schedule 8. The exact cut is in the Poisons Standard — confirm it for the product in hand.

Prescriber and pharmacist rules

How do people take it, and why does route matter?

Oils, capsules, sprays, pastilles, and inhaled flower are not interchangeable. Route changes how quickly cannabinoids appear in blood and how long they last.

Read the briefing

What should a pharmacist check before supply?

A lawful prescription, the matching TGA approval for unregistered products, schedule-appropriate storage and records, and no substitution of an unregistered product.

Jurisdiction notes

What is medicinal cannabis?

Legally manufactured cannabis products prescribed by a registered health practitioner. In Australia they are regulated medicines, not a general-sale herbal.

Read the briefing

What are cannabinoids?

Plant and related compounds that act on the endocannabinoid system. The two you will see on almost every label are THC and CBD.

Read the briefing

What does the clinical evidence actually support?

The National Academies (the successor to the Institute of Medicine on this topic) judged oral cannabinoids conclusive for chemotherapy nausea, and cannabis substantial for adult chronic pain and patient-reported MS spasticity.

Read the briefing

Where is THC-containing medicinal cannabis generally not appropriate?

TGA guidance lists previous or current psychosis, a concurrent active mood or anxiety disorder, unstable cardiovascular disease, and pregnancy, planning pregnancy, or breastfeeding.

Read the briefing

How is medicinal cannabis accessed in Australia?

Unapproved products go through TGA Special Access Scheme Category B or Authorised Prescriber, plus state and territory poisons law. ARTG-registered products do not need SAS or AP.

State and territory rules

Why do drug interactions matter?

Cannabinoids are substrates, inhibitors, or inducers of enzymes such as CYP3A4, CYP2C9, CYP2C19, CES, and UGTs. That can change levels of other medicines — or of the cannabinoids themselves.
