About this survey


Study: Psychological factors influencing cannabis experiences: Stage One.

Please note:

This survey is not compatible with Safari browsers and mobile/tablet access.
As this study is in its later stage of data collection, you will only be asked to carry out some (not all) of the tasks stated under the "What will happen if I take part?" section below. Instead of 45 minutes, this study should take about 15 minutes to complete.


In this study we are interested in how people experience the effects of cannabis (pot, weed, marijuana) differently. For example, while some people report feeling relaxed after cannabis use, others experience anxiety, nausea, and other aversive effects. We think that several psychological factors may have a role to play in determining the unique cannabis experience of an individual, including personality, mood, and patterns of thought. We are also interested in how these factors may differ among people with varied exposure to cannabis - hence, you do not have to have tried cannabis before or be a current user to participate in this study. We would like to recruit people who are not currently being treated for psychiatric disorders or issues pertaining to substance use, and we would like to hear from people of all ages above 18 years.  

The University of Wollongong and the researchers do not in any way encourage the use of cannabis. The current project has the goal of gaining a better understanding of and minimising the risks which may be associated with recreational cannabis use.


If you would like to participate in this study, you will be presented with a series of online questionnaires. Within this online survey, you will be asked to complete some questions on your experiences with cannabis (e.g. If you are a cannabis user, how often do you use cannabis?) as well as some which tap at aspects of your personality (e.g. Do you feel that you are unable to get “close” to other people?) and mood (e.g. “I found it difficult to relax” on an Apply/Did Not Apply scale). We will ask you about your recreational use of other substances (i.e. to indicate your history and status of use) and your mental health (e.g. Have you ever been treated for any mental health issues?), some of which questions may be sensitive. You will also be asked to answer a series of questions about your thoughts, feelings, and ideas of cannabis (e.g. “Marijuana makes small things seem intensely interesting”, answered on an Agree/Disagree scale; “I use marijuana to be sociable” on a Never/Always scale).  

In between the series of online questionnaires, you will be presented with a short task which taps at attentional aspects of your thinking processes. You will be presented with a series of image pairs; these images range from pleasant to unpleasant in content. For every image pair that comes up on your screen, one of the two images will quickly be replaced with an “X”. You will be asked to respond to this “X” by pressing a key on your keyboard. All up, we estimate that these should take you about 45 minutes to complete.


You may find the unpleasant images which appear in the online task (see section above) quite confronting and feel uncomfortable viewing them. Care has been taken to exclude any pictures classified to be distressing or sexually explicit, and the pictures in this task will only be flashed briefly on your computer screen. It is unlikely that you will become distressed during the course of this study. However, if you should experience any issues you may approach the services listed below for support. Alternatively, you may get in touch with the researchers and we will be able to direct you to the appropriate support.

Some people find that answering questionnaires gets them thinking about the way they see themselves, and find that online computer tasks can be fun. Importantly, this study will help researchers to learn more about how the diverse range of cannabis experiences are shaped by factors such as personality, mood, and thought processes. Your time, input and sincere responses are highly valued and very much appreciated.

 Participants who complete both Stage One and Stage Two (see section above) will be thanked for their time with a $20 Woolworth's Group gift voucher.
