Researchers Seek To Further Understand The Effects Of Cannabis


There are about 200 million people who consume cannabis worldwide. Past research studies have shown that heavy and long term cannabis consumption is accompanied by changes to a person’s brain, cognition, and mental health. Researchers have observed that these changes may depend on the levels and interactions between the compounds (cannabinoids, e.g. delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in the cannabis plant.

This study seeks to understand the relationship between different cannabinoid compounds, and the overall well-being and brain health of long-term regular cannabis smokers. This study is a virtual study limited to certain areas of the Northern Rivers Region of New South Wales.  

Researchers are inviting adults aged 18 to 65 years old who regularly smoke cannabis. Participants must comply with the necessary study requirements. Eligible participants will be compensated for their participation in this study.

Prof. Nadia Solowij

Nadia Solowij, PhD, is a Professor in the School of Psychology, University of Wollongong and recently completed a 4-year term as an ARC Future Fellow. She has been actively researching the effects of long-term cannabis use for more than 25 years and is now the most published researcher in the world on the topic of cannabis and the brain. Her primary area of expertise is in the long-term cognitive and neural effects of cannabis. She has used neuropsychological, psychophysiological and brain imaging techniques in her investigations of memory, cognition and brain structure and function in adult and adolescent cannabis users and people with schizophrenia and comorbid cannabis use.
