If accurate, this prevalence would indicate that most clinicians are encountering cannabis users regularly, whether disclosed or not. Clinical Summary Mamedica reports that 66% of British adults (approximately 11.45 million people) have used cannabis, though the specific timeframe, methodology, and definition of ‘use’ are not provided in the available information. This prevalence estimate is substantially higher than most official surveys, which typically report lifetime [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) rates of 20-30% in developed countries. The discrepancy could reflect changing social acceptance, survey methodology differences, or sampling bias. Dr. Caplan’s Take “If this data holds up to scrutiny, it confirms what many of us see clinically — cannabis use is far more common than patients typically disclose. This reinforces why we need to ask about cannabis use routinely and non-judgmentally, just like we do with alcohol.” Clinical Perspective 🧠 Clinicians should maintain routine, matter-of-fact screening for cannabis use regardless of official prevalence estimates, as patient disclosure often lags behind actual use patterns. This data, if validated, supports implementing standard cannabis use assessment in medical histories, medication reconciliation, and pre-procedural evaluations. The key clinical question remains creating environments where patients feel safe to disclose use honestly. 💬 Join the Conversation Have a question about how this applies to your situation?
