In 2016, a study published in the journal PLOS ONE found that the average Australian smoker had used cannabis about one-and-a-half times.
It said that the risk of developing the serious medical condition known as “cannabis psychosis” had risen from 1.8 per cent to 2.1 per cent.
“This is a substantial increase from a few years ago,” Professor David Nutt, of the University of Sydney’s School of Medicine, said in a statement.
“In addition, the number of cannabis-related deaths in Australia has increased by approximately 15 per cent since 2016.”
