With increasing [medical cannabis](https://cedclinic.com/therapeutic-benefits-of-thc/) use, clinicians need evidence-based guidance for patient safety discussions about driving impairment duration and severity. Clinical Summary This scoping review examined research on cannabis effects on higher-order driving skills like decision-making, hazard perception, and multitasking while driving. The review likely synthesized studies measuring real-world driving performance rather than just reaction time or basic motor tasks. Cannabis impairment of complex cognitive functions may persist longer than patients realize and varies significantly based on dose, THC concentration, and individual tolerance. The distinction between simple motor skills and complex driving cognition is clinically important for patient counseling. Dr. Caplan’s Take “I tell patients that feeling ‘fine’ doesn’t mean you’re safe to drive — cannabis affects judgment and complex decision-making in ways that aren’t immediately obvious to the user. This review helps us move beyond ‘wait a few hours’ to more nuanced, evidence-based driving safety discussions.” Clinical Perspective 🧠 Clinicians should counsel patients that cannabis impairment extends beyond feeling intoxicated, particularly for complex tasks requiring split attention and rapid decision-making. Ask patients about their driving patterns and timing relative to [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/). Consider that [medical cannabis](https://cedclinic.com/therapeutic-benefits-of-thc/) patients may have different tolerance and impairment profiles than recreational users studied in most research. 💬 Join the Conversation Have a question about how this applies to your situation?

This study has been rated #70 for “Notable Clinical Interest” by CED Clinical Relevance. It represents emerging findings or policy developments in [cannabis medicine](https://cedclinic.com/essential-oils-industrial-hemp-antimicrobial-benefits/) that clinicians should monitor closely. #### What are the main safety concerns regarding cannabis and impairment? The research focuses on patient safety issues related to cannabis impairment, particularly concerning THC effects. Healthcare providers need to understand how [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) may affect patient functioning and decision-making capabilities. #### How does cannabis use impact driving ability? THC can significantly impair driving performance and reaction times. Patients using medical cannabis should be counseled about the risks of driving while under the influence and local legal restrictions. #### What should clinicians know about THC-related impairment? THC can cause cognitive and motor impairment that varies based on dosage, frequency of use, and individual tolerance. Clinicians should assess patients’ ability to safely perform daily activities while using THC-containing cannabis products. #### How can healthcare providers address cannabis impairment with patients? Providers should discuss timing of cannabis use, potential impairment duration, and safety precautions with patients. Regular monitoring and patient education about recognizing impairment signs are essential for safe medical cannabis use.
