Is Cannabis Legal in South Australia? 2026 Update

Current Status: Decriminalised (Small Amounts)

South Australia was the first Australian state to decriminalise cannabis in 1987 via the Cannabis Expiation Notice (CEN) system. Adults found with up to 25g of cannabis or one non-hydroponic plant receive an expiation notice (fine) rather than criminal charges. Medical cannabis is available through the TGA. Seeds may be purchased as adult novelty souvenirs.

Medical vs Recreational Cannabis in South Australia

South Australia has decriminalised cannabis possession for small amounts under its expiation notice system. This means small-quantity offences attract a fine rather than criminal charges. However, there is no regulated recreational sales framework and cultivation remains illegal. Medical cannabis is available through the TGA Special Access Scheme with a prescription from an authorised doctor.

Home Cultivation Rules

While South Australia has decriminalised possession of small amounts of cannabis, home cultivation remains illegal. The decriminalisation provisions apply to possession and personal use only — growing plants will result in criminal charges. Cannabis seeds may be purchased and possessed as adult novelty souvenirs and collector genetics.
