Marijuana and Anesthesia: The Hidden Dangers Revealed

Marijuana and Anesthesia

When it comes to undergoing surgery, it is essential to understand the potential interactions between marijuana and anesthesia. Recent evidence has shed light on the risks associated with marijuana use before surgery, making it important to consult with an anesthesiologist and abstain from marijuana use to ensure a safe surgical experience [1].

Understanding Anesthesia and Marijuana Use

Anesthesia is a medical procedure used to induce a temporary loss of sensation or consciousness during surgeries or other medical procedures. It involves the administration of medications that affect the central nervous system, altering the body's response to pain and inducing a state of controlled unconsciousness.

Marijuana, a psychoactive substance derived from the Cannabis plant, has gained popularity for its recreational and medicinal use. However, its use can have implications when it comes to anesthesia. Regular users of marijuana generally require higher doses of anesthesia medications to achieve the same level of sedation in comparison to non-users. For example, regular marijuana users (daily to weekly) may need over three times the amount of propofol, a commonly used anesthesia medication, to achieve adequate sedation during procedures like endoscopies [2].

Effects of Marijuana on Anesthesia Dosing

The effects of marijuana on anesthesia dosing can be attributed to the way marijuana interacts with the body's metabolism and the liver's ability to break down medications. Tetrahydrocannabinol (THC), the primary psychoactive compound in marijuana, can induce certain enzymes in the liver, leading to the faster breakdown of anesthesia medications. As a result, higher doses of anesthesia may be required to achieve the desired level of sedation and pain control during surgery.

It is important to note that marijuana use before surgery can lead to serious complications of anesthesia. Increased doses of anesthesia medications can result in extended recovery times, delayed awakening from anesthesia, and higher risks of postoperative pain. Moreover, marijuana use before surgery has been associated with increased opioid use during and after surgery, putting individuals at risk for opioid use disorder.

Considering the potential risks, anesthesiologists recommend that marijuana use should be completely avoided on the day of surgery. This includes smoking or inhaling marijuana as well as consuming edible marijuana due to preoperative fasting guidelines. By abstaining from marijuana use before surgery, individuals can help ensure safer and more effective anesthesia administration.

Understanding the impact of marijuana on anesthesia dosing is crucial for both patients and healthcare providers. It is important to disclose any marijuana use to your anesthesiologist during the preoperative evaluation to ensure appropriate anesthesia planning and minimize the potential risks associated with marijuana use during surgery.

In the next sections, we will explore the risks of marijuana use before surgery, precautions and recommendations for individuals using marijuana, as well as other health concerns and complications that may arise in the context of marijuana and anesthesia interactions.
