Data from the general Australian population (Australian Institute of Health and Welfare, 2011, 2014)), and data from border seizures, seizures in Australia and police arrest data (Australian Crime Commission, 2015) have indicated a rising trend in the use and supply of hallucinogens.
This trend is also found among regular psychostimulant users (RPU), a unique population group of illicit recreational users targeted by the Ecstasy and Related Drugs Reporting System (EDRS). In NSW, there was a significant increase in the proportion of LSD users from 2014 to 2015.
Given these trends, the aim of the current study was to explore hallucinogen use among frequent recreational drug users. Seven-hundred-and-sixty-three RPU were recruited for the 2015 EDRS and were asked about their illicit drug use, mental and physical health and information about their drug sources.
