If you’ve just had surgery with general anesthesia and you’re wondering whether it’s okay to have a celebratory drink or use recreational drugs like marijuana afterward, you’re asking a very common question. As a CRNA with 20 years of experience, I understand that after the stress of surgery, many people look forward to relaxing with a glass of wine, a beer, or something else. My goal is to reassure you that while your body is recovering from both the surgery and the anesthesia, it’s best to hold off for a short time. The good news is that with a little patience, you can safely enjoy these things again soon. Let’s walk through the facts together so you feel informed and at ease.
Why We Recommend Waiting After General Anesthesia
General anesthesia is designed to wear off relatively quickly—most people feel back to their normal selves within 24 hours for simple activities. However, even after you wake up, small amounts of anesthesia medications can linger in your system, and your body is still healing from the procedure itself. Adding alcohol or recreational drugs too soon can interfere with this healing process, increase side effects, or interact with any pain medications you’re taking.
The key message is this: you are not in any danger if you wait a short period, and waiting actually helps you recover faster and more comfortably. Your anesthesia team and surgeon will give you personalized instructions, but here are the general guidelines that apply to most patients.

Alcohol After General Anesthesia: A Short Break Is All It Takes
Alcohol and general anesthesia don’t mix well right after surgery for a few important reasons:
It can make you feel more drowsy or dizzy than usual because the effects of anesthesia and alcohol can add up.
Alcohol can increase bleeding risk and slow wound healing, especially if you’re taking pain medications or antibiotics.
It may worsen postoperative nausea or interact with any medications you’re prescribed.
How long should you wait?
For most people, it’s safest to avoid alcohol for at least 24 hours after general anesthesia. Many surgeons recommend waiting 1–2 weeks (or until you’ve finished any prescribed pain medications or antibiotics) before having a drink, especially after larger surgeries. This short wait gives your body time to clear the anesthesia completely, finish post-op pain medications, and start healing properly. Once that time has passed and your doctor gives the green light, moderate drinking is usually fine—just listen to your body and don’t overdo it while you’re still recovering. We don't want to see you back in the OR too soon. ; )
If you’re a regular or heavy drinker, it’s especially helpful to mention this to your anesthesia provider before surgery. We can help you plan a safe approach and avoid any withdrawal issues that could complicate recovery.

Recreational Drugs Like Marijuana After General Anesthesia
Marijuana (cannabis) and other recreational drugs can affect how your body responds to anesthesia and pain medications, and the same caution applies afterward. Smoking or vaping after anesthesia can irritate your airways and impair surgical wound healing, while any form of cannabis may increase nausea, affect pain control, or interact with medications.
How long should you wait?
Most experts recommend avoiding marijuana for at least 24–72 hours after general anesthesia, and longer if you had a procedure involving your lungs, abdomen, or throat. Smoking or vaping right after surgery and anesthesia can cause significant coughing which can affect incision sites and raises blood pressure, so it’s best to give your body time to settle. Edibles or other forms still require caution because they can amplify drowsiness or affect judgment while residual anesthesia or pain medication effects are present.
If you use marijuana regularly, let your anesthesia team know ahead of time. We adjust our plans to keep you safe and comfortable, and we can talk with you about resuming use once you’re further along in recovery. The goal is always to support your healing without unnecessary setbacks.
What This Means for You: A Reassuring Timeline
Here’s a simple, typical timeline that applies to many patients after general anesthesia:
First 24 hours: No alcohol, no recreational drugs (including marijuana), and no driving or operating machinery. Rest, stay hydrated, and follow your pain medication schedule.
Days 2–7 (or longer, depending on your surgery): Continue avoiding alcohol and recreational drugs until your surgeon or anesthesia provider says it’s okay—especially if you’re still taking prescription pain relievers.
After clearance: Once you’re feeling better and off stronger medications, moderate use is usually fine. Always check with your doctor first, particularly if your surgery was major or you have other health conditions.
Remember, these are general guidelines. Your specific situation—type of surgery, your overall health, and any medications—may mean slightly different timing. Your care team will give you clear, personalized instructions before you go home and you can always ask for clarification.
Why It’s Worth Waiting
Waiting a short time protects the investment you’ve made in your surgery and recovery. Alcohol and recreational drugs can slow healing, increase the chance of complications, or make you feel worse when your body is already working hard to bounce back. By giving yourself this brief pause, you’re setting yourself up for a smoother, more comfortable recovery—and you’ll be able to enjoy that drink or whatever you choose even more once you’re truly feeling like yourself again.

Final Thoughts
The short answer is: it’s best to avoid alcohol and recreational drugs like marijuana for at least 24 hours after general anesthesia, and often longer (1–2 weeks for alcohol, or until cleared by your doctor for marijuana). This isn’t about being overly strict—it’s about giving your body the best chance to heal comfortably and safely. Modern anesthesia is designed to wear off cleanly, and with a little patience, you’ll be back to your normal routines without worry.
