Which public health considerations arise regarding cannabis impairment?

• A. Roadside impairment testing
• B. Education campaigns only
• C. Roadside testing and education
• D. Pharmacologic treatment at clinics

Answer: (C)

Addressing cannabis impairment from a public health perspective requires both detecting impairment in real time and preventing it through education. Roadside impairment testing provides enforcement tools to identify drivers who are impaired at the moment, using standardized field tests and, when appropriate, chemical tests. Education campaigns complement this by informing the public about how cannabis affects driving, how potency and product type influence impairment, and the importance of safe transportation alternatives. Together, testing helps deter risky driving while education reduces the occurrence by shaping behavior and awareness. Pharmacologic treatment at clinics, while important for cannabis use disorders, doesn't directly address driving impairment in the moment, so it isn’t the primary public health approach to impairment on the road.
