Co-author and associate professor of marketing Dr Kirsten Robertson said the study, published in the journal Substance Abuse; Research and Treatment, could help inform discussions surrounding the legalisation of the drug in the lead up to the cannabis referendum.
“The findings clearly suggest that despite recreational cannabis being illegal, its use is normalised in the student culture.
“Overall, 82% of students said their peers had used cannabis before, and 39% said their peers used cannabis regularly. The vast majority of students also stated that cannabis is very easy to acquire and is readily available at typical social occasions.”
Co-author Dr Karen Tustin said 93% of participants stated the law did not act as a deterrent for cannabis users.
The results of the study showed prohibition was not working, she said.
“Responses such as ‘it’s such a normal thing; everyone does it, it feels normal to see it in everyday life, and I associate it the same as seeing alcohol’ were common. Participants also made statements that the law was soft and police tend to turn a blind eye to cannabis, and consequences in the unlikely event of being caught with cannabis were likely to be minimal.”
The study found that many students reported forgetting recreational cannabis was illegal, that they perceived it as legal and that they did not view its use as a crime.
Perceptions of their peers who are recreational cannabis users varied depending on the frequency of their use of the drug.
Participants said their peers who sometimes used cannabis were social and "normal". However, peers who were heavy users were described as "underachievers, unreliable, and unhealthy", and raised concerns regarding their well-being.
“With this in mind, we think public policy should focus on strengthening social norms that discourage heavy use,” Dr Tustin said.
“Given that cannabis use is normalised and heavy use is discouraged by concern for heavy users - rather than any concern for the law – we believe our findings support a harm-minimisation strategy and, specifically, a health model, for regulating recreational use of cannabis,” Dr Robertson added.
