Bridging <scp>THC</scp> Knowledge Gaps for Safer Roads: A Call for Action

The rising cases of cannabis-impaired driving present a looming public safety concern that's currently addressed through varying state regulations. However, these regulations are yet validated and lack scientific robustness. One of the roadblocking factors is our insufficient understanding of THC's pharmacokinetics (PK) and pharmacodynamics (PD) due to limited clinical data. Therefore, we call for joint efforts among researchers and policymakers to conduct more comprehensive cannabis PK/PD studies to improve and validate existing cannabis driving regulations.
