Regular cannabis use has become more accepted than smoking tobacco, the latest National Drug Strategy Household Survey (NDSHS) has found.

The 2019 data, compiled by the Australian Institute of Health and Welfare and released on Friday, asked around 20,000 people aged 14 and over about their attitudes towards drugs.

It found, for the first time, 20% of respondents supported regular cannabis use compared to 15% in support of tobacco.
