Study Reveals Smoking Weed Increases Anesthesia Needs
A recent study indicates that smoking or vaping cannabis significantly raises the amount of anesthesia required during medical procedures.
Cannabis smokers need more anesthesia than non-users during procedures.
Edible cannabis users require less anesthesia, according to the study.
Patients should disclose their cannabis consumption methods to anesthesiologists.
A new study presented at the American Society of Anesthesiologists' annual meeting has revealed that the method of cannabis consumption can significantly impact the amount of anesthesia required during medical procedures. Specifically, individuals who smoke or vape cannabis may need higher doses of the anesthetic propofol compared to those who do not use cannabis at all.
The research involved a review of records from 264 patients who underwent either a colonoscopy or upper endoscopy, with findings indicating that those who smoked or vaped cannabis required an average of 169 milligrams of propofol. In contrast, non-users needed only 139 milligrams, while those consuming cannabis edibles required even less, averaging 114 milligrams. This trend was particularly pronounced during upper endoscopies, where smokers needed 193 milligrams compared to 151 milligrams for non-users.
Lead researcher Dr. Basavana Goudra emphasized the importance of patients being transparent with their anesthesiologists regarding their cannabis use. He noted that simply asking if a patient uses cannabis is no longer sufficient; understanding the method of consumption—whether smoking, vaping, or edibles—is crucial for proper anesthesia management. This information helps anesthesiologists tailor their approach to meet individual patient needs.
The study's findings suggest that the body's processing of cannabis varies significantly based on consumption methods. Smoking or vaping delivers THC quickly through the lungs, leading to immediate effects, while edibles are metabolized by the liver, resulting in a slower onset of effects. Additionally, the irritation caused by smoking or vaping may necessitate deeper anesthesia during procedures like upper endoscopy, where a tube is inserted through the mouth.
Despite these findings, researchers advise that individuals who smoke cannabis should not avoid necessary medical procedures like upper endoscopies. Instead, they should provide complete and accurate information about their cannabis use to ensure that anesthesiologists can adjust their anesthesia protocols accordingly. The study's results are preliminary and await publication in a peer-reviewed journal.
