This matters clinically because patients need evidence-based guidance on functional impairment, not blanket warnings that may undermine therapeutic compliance. Clinical Summary Federal agencies have launched a public awareness campaign warning against marijuana-impaired driving in advance of April 20th, a date associated with cannabis consumption. The campaign appears to focus on general impairment messaging rather than evidence-based thresholds or duration guidance. Current research shows cannabis impairment is dose-dependent and individual-variable, with peak impairment typically occurring within 1-3 hours of inhalation, though reliable field testing remains problematic. Unlike alcohol, there is no established blood THC level that correlates consistently with functional impairment across populations. Dr. Caplan’s Take “I counsel patients that responsible [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) means understanding your individual response and timing—not avoiding driving indefinitely. The real clinical question isn’t whether cannabis can impair driving, but helping patients understand when they’re functionally impaired versus simply THC-positive.” Clinical Perspective 🧠 Clinicians should provide individualized guidance on timing and dosing rather than blanket restrictions. Patients benefit from understanding that impairment and detection are different phenomena, and that responsible use requires honest self-assessment of functional capacity. Consider discussing onset/offset timing specific to their consumption method and personal tolerance. 💬 Join the Conversation Have a question about how this applies to your situation?
