Translational hurdles with cannabis medicines.

It is important that real-world evidence (RWE) is used to complement rather than replace randomised controlled trial (RCT) evidence on cannabis medicines. Technological advances have created the opportunity to explore diverse and novel sources of cannabis medicine RWE. Although RWE may be more reflective of real-world clinical practice, it cannot provide conclusive evidence of the safety and efficacy of cannabis medicines. While acknowledging its limitations, RWE may nonetheless provide some guidance on safety and adverse events of cannabis medicines. RWE has already had a significant impact on the regulation of cannabis medicines.
