This study addresses a critical gap in perioperative care for the growing population of cannabis users. Understanding anesthetic requirements helps prevent inadequate sedation and intraoperative awareness while avoiding oversedation complications.
This prospective study of patients undergoing third molar extraction under IV general anesthesia found that cannabis users required significantly higher doses of propofol compared to non-users. The investigators developed a risk stratification system based on cannabis exposure years (CEYs), identifying patients with ≥2-3 years of multiple daily use as high-risk for increased anesthetic requirements. The study provides practical clinical guidance for adjusting propofol dosing in cannabis-exposed patients, though it was limited to a single procedure type and anesthetic agent.
“This confirms what many anesthesiologists have observed clinically – regular cannabis users often need more medication to achieve adequate sedation. The risk stratification approach gives us a practical framework for preoperative planning rather than guessing at dosing adjustments.”

FAQ
Do cannabis users require more anesthesia during oral surgery?
Yes, this study found that cannabis users required significantly more propofol (total milligrams of propofol, TMP) during third molar removal under intravenous general anesthesia compared to non-users. The increased anesthetic requirement appears to correlate with both duration and frequency of cannabis use.
Which cannabis users are at highest risk for requiring more anesthesia?
Cannabis users with ≥2-3 years of use and multiple daily sessions are considered high risk for increased propofol requirements. The study used cannabis exposure years (CEYs) to stratify patients into high-risk, moderate-risk, and low-risk categories based on duration and frequency of use.
Should I tell my anesthesiologist about my cannabis use before surgery?
Yes, it’s essential to disclose cannabis use to your anesthesiologist before any procedure requiring general anesthesia. This information allows the anesthesia team to properly plan and adjust medication dosages to ensure safe and effective anesthesia during your procedure.
How should anesthesiologists prepare for cannabis users undergoing oral surgery?
Anesthesiologists should obtain detailed cannabis use history including duration and frequency of use to assess risk level. They should be prepared to administer higher doses of propofol and closely monitor patients, as cannabis users may require significantly more anesthetic agents to achieve adequate sedation.
Is this finding limited to oral surgery or does it apply to other procedures?
This specific study focused on third molar removal under intravenous general anesthesia, so the findings are most directly applicable to oral surgery procedures. However, the underlying mechanism suggests cannabis users may require higher anesthetic doses across various surgical procedures, though more research is needed to confirm this broader application.
