ASX Cannabis Stocks: 10 Biggest Companies
Australia’s medical cannabis market is maturing. Investors interested in cannabis and hemp companies should learn about the 10 biggest cannabis stocks on the ASX.

While Australia has yet to legalise all forms of cannabis, the country is a growing medical cannabis and hemp market, with many companies manufacturing, researching and exporting the plant-based product.
Medical cannabis was federally legalised in 2016, and the export of cannabis from Australia was legalised in 2018. As for recreational use, the only state to legalise recreational use and possession so far is the Australian Capital Territory, which did so in 2020, but it did not establish a regulated recreational cannabis market.
The country's medical cannabis market has been steadily expanding in size and scope. A Penington Institute report shows that Australians spent approximately AU$400 million on medicinal cannabis in the first half of 2024, 72 percent higher than the AU$234 million they spent over the entirety of 2022.
Moving forward, Grandview Research forecasted a compound annual growth rate of 33.6 percent between 2024 to 2030 for the country's medical cannabis market.
Australian cannabis companies listed on the ASX are operating in this space, creating goods such as medicines, flower and hemp products. Some ASX-listed cannabis companies are also producing recreational cannabis in other countries.
Here the Investing News Network profiles the 10 biggest cannabis stocks on the ASX by market cap. Australian cannabis stocks are listed in order of market cap from largest to smallest, with data compiled using TradingView’s stock screener on March 18, 2025.
