GPs Screen for Cannabis Problems More Than Nurses, but Both Face Barriers
General practitioners were more likely than nurses to screen for and address cannabis-related problems, but both professions reported significant barriers including limited time, knowledge gaps, and competing priorities.
Quick Facts
What This Study Found
Researchers surveyed 503 GPs and 161 nurses about their cannabis-related knowledge, beliefs, and clinical behaviors. GPs were more likely to have screened patients for cannabis use and provided related services, but they also reported more barriers: time constraints, lack of interest, and feeling that other issues took priority.
Nurses reported less knowledge, fewer skills, and less confidence that cannabis screening fell within their professional role. However, perceived screening skills predicted actual screening behavior for both professions, suggesting that training could increase service delivery.
Key Numbers
503 GPs and 161 nurses surveyed. GPs were more likely to screen for cannabis use. Perceived screening skills predicted actual screening and referral to AOD services. Knowing a regular cannabis user increased referral likelihood.
How They Did This
Cross-sectional survey distributed at Healthed conference seminars focused on women's and children's health in Australia. Differences between GPs and nurses were analyzed with chi-square tests and t-tests. Logistic regression identified predictors of cannabis-related service provision.
Why This Research Matters
Cannabis-related problems represent a significant unmet treatment need. Most people who need help for cannabis issues visit their GP or interact with nurses, making primary care a logical intervention point. But if clinicians feel unprepared or unconvinced of their role, opportunities for early intervention are missed.
The Bigger Picture
This study highlights a gap between the potential of primary care to address cannabis problems and the current reality. Training programs that build screening skills and clarify professional roles, particularly for nurses, could substantially increase the number of people receiving early help.
What This Study Doesn't Tell Us
The survey was distributed at conferences focused on women's and children's health, so attendees may not represent the broader GP and nursing workforce. Self-reported behaviors may not accurately reflect actual clinical practice. The study was conducted in Australia, which may limit applicability elsewhere.
Questions This Raises
- ?Would targeted training programs increase cannabis screening rates in primary care?
- ?Could nurses play a larger role if given explicit role authorization and skill development?
- ?How do screening rates differ in settings outside of women's and children's health?

What do these levels mean? →Frequently Asked Questions
Why do nurses screen for cannabis less than GPs?
Nurses reported less knowledge about cannabis, fewer perceived screening skills, and less certainty that cannabis screening was part of their professional role. These barriers suggest the issue is more about training and role clarity than willingness.
What predicted whether a clinician would screen for cannabis?
The strongest predictor was perceived screening skills. Clinicians who felt competent in cannabis screening were more likely to do it. Personally knowing a regular cannabis user also increased the likelihood of making referrals.
