Many people use cannabis for sleep, anxiety, or pain relief. Before oral surgery, however, cannabis in any form can affect how your body responds to anesthesia and medications. Knowing when to stop helps reduce risk and supports a smoother procedure.

When Should You Stop Using Cannabis Before Oral Surgery?

Cannabis should be stopped 72 hours before oral surgery. This includes smoking, vaping, edibles, and CBD products. If you use cannabis products regularly, you may be advised to stop earlier depending on your health history and the anesthesia planned.

Stopping ahead of time helps your care team manage anesthesia  more accurately and lowers the risk of unexpected reactions.

How Cannabis Affects Anesthesia and Surgical Safety

Cannabis use can affect several aspects of anesthesia and surgical safety, including:

  • Changes in anesthesia response that can increase or decrease medication needs
  • Effects on heart rate and blood pressure
  • Increased airway sensitivity, especially with smoking or vaping

What to Tell Your Oral Surgeon Before Surgery

Your oral surgeon should be aware of any cannabis use before your procedure. This includes how often you use it, what form you use, and when you last used it.

Sharing this information helps your care team adjust anesthesia safely and plan your treatment more accurately.

What About After Oral Surgery?

Cannabis should still be used with caution after oral surgery. In the early healing phase, it may increase dryness, interact with prescribed medications, and affect how your body recovers.

Smoking or vaping should be avoided until your surgeon clears you. Suction from smoking after dental extractions can disrupt healing and  increase the risk of complications such as dry socket. Edibles and CBD products should also be delayed, especially while taking pain medication.

For specific timing, follow your surgeon’s instructions based on your procedure and recovery.
