This large cohort study provides the first comprehensive analysis of cannabis-specific perioperative risks in orthopedic trauma, addressing a critical knowledge gap as cannabis use becomes increasingly prevalent. Understanding these risks is essential for informed surgical consent and perioperative planning when cessation may not be realistic.
This retrospective cohort study analyzed 16,112 adult patients with upper extremity fractures requiring surgical fixation from 2015-2023, comparing outcomes across cannabis-only, nicotine-only, concurrent users, and matched non-users. The study found both cannabis and nicotine use independently associated with increased surgical complications, medical complications, and new postoperative psychosocial diagnoses including anxiety, depression, opioid use disorder, and chronic pain. Propensity score matching was used to control for confounders, though residual confounding remains a limitation in this observational design.
“This data confirms what many of us have observed clinically – cannabis use appears to carry distinct perioperative risks beyond those of tobacco. The association with increased chronic pain and opioid use disorder is particularly concerning and warrants careful preoperative counseling.”

FAQ
Should I advise cannabis users to stop before upper extremity fracture surgery?
This study demonstrates that cannabis use is independently associated with increased surgical, medical, and psychosocial complications following upper extremity fracture fixation. While cessation may not always be feasible in trauma settings, patients should be counseled about these elevated risks and monitored more closely perioperatively.
Are the risks from cannabis use as significant as those from nicotine use?
Yes, this research shows that cannabis and nicotine use are independently associated with adverse outcomes, meaning both substances carry distinct risks. Patients using both substances concurrently face compounded risks and require the most intensive perioperative management and monitoring.
What specific complications should I watch for in cannabis-using patients after upper extremity surgery?
Cannabis users showed increased rates of surgical complications, medical complications, and new postoperative psychosocial diagnoses including anxiety, depression, opioid use disorder, and chronic pain. These patients require enhanced surveillance for both physical and mental health complications during recovery.
How should cannabis use affect my perioperative planning and patient counseling?
Cannabis users should receive comprehensive preoperative counseling about increased complication risks and may benefit from enhanced perioperative support services. Consider involving mental health resources early and developing more intensive pain management strategies given the higher risk of chronic pain and opioid use disorder.
Does cannabis use affect coagulation parameters that could impact surgical planning?
The study evaluated coagulation parameters as secondary outcomes in cannabis users undergoing upper extremity fracture fixation. While specific coagulation results aren’t detailed in the summary, this represents an important consideration for surgical planning that warrants preoperative assessment in cannabis-using patients.
