Cannabis Cultivation & Trafficking Laws in South Australia

 

Cannabis cultivation offences in South Australia are taken very seriously under the Controlled Substances Act 1984 (SA). Whether you are caught growing a few plants for personal use or cultivating a larger commercial quantity, the penalties can be severe.

If you are facing cannabis charges, it is vital to understand the law and seek early advice from an experienced criminal lawyer in Adelaide.
