A patient who regularly uses marijuana presents for dental treatment with a strong odor of cannabis. What is the most appropriate action?

Correct answer: C. Reschedule the appointment

• A. Proceeding with treatment on a potentially impaired patient is inappropriate and raises safety and consent concerns.
• B. Dose reduction is not the correct response — the primary concern is patient impairment and safety.
• C. Correct. If a patient presents with evidence of current marijuana intoxication (strong smell, behavioral signs), the appointment should be rescheduled. The patient may not be able to give valid informed consent and has impaired judgment. This follows the same protocol as alcohol intoxication.
• D. Supplemental oxygen does not address the issue of patient impairment.
