The impact of recreational cannabinoids on peri-operative outcomes

Patterns of Marijuana Use and Nicotine Exposure in Patients Seeking Elective Aesthetic Procedures

BACKGROUND

With the increasing legalization and popularity of marijuana, it is frequently and sometimes unintentionally combined with nicotine-containing products. As a consequence, patients may fail to accurately report usage during preoperative examinations or remain unaware of the inclusion of nicotine. This poses a challenge for clinicians in identifying preoperative nicotine exposure. This study aimed to establish normative data on the use of marijuana and nicotine in plastic surgery patients and correlate it with urine nicotine and cotinine levels.

METHODS

All consecutive patients presenting to the authors' clinic seeking elective procedures were identified. Patients were surveyed on marijuana and nicotine use, and provided a urine sample for analysis. The survey responses, urine results, surgical treatments, and clinical outcomes were followed up prospectively.

RESULTS

A total of 135 patients completed the survey and were categorized as nonusers (50%), active nicotine users (19%), active marijuana users (7%), active users of both (13%), or past users (11%). Marijuana users who denied nicotine use showed significantly elevated nicotine and cotinine levels compared with nonusers (average nicotine level, 23.1 ± 13.5 ng/mL [P = 0.00007]; average cotinine level, 221.2 ± 141.8 ng/mL [P = 0.0002]). Fewer than a third of active marijuana or nicotine users reported active use of these products during clinical encounters. There was no difference in urine levels, reported use, or other patient characteristics in patients with and without postoperative complications.

CONCLUSION

This is the first descriptive study to document elevated urine nicotine levels in self-reported marijuana users in an urban, diverse patient population seeking elective plastic surgery procedures.

Cannabinoids in dermatologic surgery

Though known as a medicinal herb for centuries, the recent legalization of cannabinoids across many states has ushered in a new era where cannabinoids have become a popular treatment option among clinicians and patients alike. Cannabinoids have demonstrated efficacy in wound healing, reducing inflammation, ameliorating pain, and have shown potential as an antitumor agent. As a result, cannabinoids have been rapidly woven into the fabric of modern medicine. However, the utility of cannabinoids in dermatologic surgery has not been explored to date. In this article, we review the current literature to discuss the potential impact of cannabinoid use in dermatologic surgery.
