Measuring the Size of Australia’s Illegal Cannabis Market and Potential Tax Revenue from Legalization

The debate over legalizing cannabis in Australia has been a hot topic, with the potential for billions in tax revenue at stake. A recent senate inquiry is set to report on a bill that could pave the way for legalizing cannabis in the country.

The aim of legalizing cannabis is to combat organized crime, protect minors, and ensure public health through strict regulations. The potential windfall from taxes on a legal market is estimated to be in the billions, with the Parliamentary Budget Office projecting a USD 28 billion boost in the first decade.

However, experts believe this estimate may be too high, with a more realistic figure being around USD 13 billion. To determine the size of the illegal cannabis market and potential tax revenue, researchers are looking at both supply and demand-side approaches.

By analyzing survey data on cannabis use, researchers estimate that Australia consumes around 441 tonnes of cannabis per year, with an average of 2.5 grams per week per user. The challenge lies in attracting frequent users to the legal market, as pricing and quality are key factors.

To ensure the success of a legal cannabis market, policymakers must carefully consider pricing, taxation, and implementing systems to track the supply chain. Without these measures, the legal market may struggle to compete with the illegal market, potentially undermining efforts to curb organized crime and generate significant tax revenue.

As the debate continues, the future of cannabis legalization in Australia remains uncertain, with the potential for significant economic impact hanging in the balance.
