If you're caught with less than 50 grams of cannabis in Canberra, it's unlikely you'll end up with a criminal record. But just a few kilometres away in New South Wales, carrying the same amount of marijuana can mean a conviction or even jail time. The variation between drug laws in each jurisdiction is a complex issue. The ACT's scheme, called the Simple Cannabis Offence Notice (SCON), was first introduced in 1992 and amended in 2005 to exclude all hydroponically grown plants. It's part of a broader drug diversion strategy, which aims to move drug users away from the criminal justice system and into education and treatment programs.
