A recent study by scientists in Colorado has revealed that people who regularly use cannabis may require more than double the usual amount of sedation during medical procedures.
The findings, published in The Journal of the American Osteopathic Association, highlight the potential challenges cannabis users face when undergoing procedures like colonoscopies or surgeries that require anesthesia.
The research, led by Dr. Mark Twardowski and his team, analyzed the medical records of 250 patients who underwent endoscopic procedures in Colorado after the state legalized recreational cannabis in 2012.
They focused on patients who reported daily or weekly use of cannabis, whether by smoking or ingestion.
The study found that regular cannabis users needed significantly higher doses of common sedative drugs to achieve the same level of sedation as non-users.
Specifically, these patients required 14% more fentanyl, 20% more midazolam, and a striking 220% more propofol. These medications are widely used for sedation during medical procedures like colonoscopies.
This increase in sedative requirements raises safety concerns. Many sedatives have dose-dependent side effects, meaning that as the dosage increases, so do the risks.
One major concern is the suppression of respiratory function, a known side effect of these drugs. Higher doses could increase the likelihood of breathing problems, which could lead to complications during or after procedures.
The researchers suggest that cannabis may alter the body’s metabolism in ways that make sedative medications less effective.
Although the exact mechanism is not fully understood, this interaction underscores the importance of healthcare providers knowing about a patient’s cannabis use before administering anesthesia or sedation.
Chronic cannabis use has also been linked to other health issues, including persistent nausea and vomiting, a condition known as cannabinoid hyperemesis syndrome.
Previous studies have shown that frequent cannabis users may also require higher doses of general anesthesia and may experience higher rates of post-operative complications, such as seizures.
To address these concerns, the researchers recommend adding specific questions about cannabis use to patient intake forms. This information would help medical professionals adjust sedation plans to ensure patient safety and effective care.
For patients, this study serves as a reminder to be transparent with their doctors about cannabis use. Whether used recreationally or for medical purposes, cannabis can influence how other medications work in the body.
By providing accurate information, patients can help their healthcare providers better manage their treatment and reduce potential risks.
As cannabis becomes increasingly legal and widely used, understanding its effects on medical care is becoming more important.
This study highlights the need for further research to uncover how cannabis interacts with medications and impacts overall health, particularly during medical procedures requiring sedation.
