Can I smoke weed after rhinoplasty 4 weeks post op?

Certainly nobody would encourage it but you're not likely to do any significant direct harm to your healing at 4 weeks.  Make sure your behavior in general doesn't increase risk of nasal injury. I would check with your operating surgeon to confirm though. 

Thank you very much for enquire.

Swelling after a rhinoplasty depends of the surgery complexity. In this regard, the nasal swelling Post-op It can last from two weeks to two months. To reduce this swelling, I recommend you perform delicates daily lymphatic drainage massage therapy over the face (around the nose) avoid sun exposure, and take pain/inflamation pills, as your surgeron precribe you. Kind regards,  Dr. Emmanuel Mallol Cotes.-  

Thank you for your question. You should absolutely consult with your physician about your smoking habits in order to obtain the most reliable and individualized medical advice. It's best to avoid smoking for at least two weeks prior to rhinoplasty. This applies not only to conventional cigarettes, but also to marijuana. Also make sure to avoid smoking marijuana for at least two weeks after surgery as it may interfere with your healing process. Smoking after surgery may restrict the flow of blood to the healing areas, exacerbate swelling, and prolong recovery.  I'd recommend to consult with your plastic surgeon as he or she may have different guidelines for smoking. 
An in-person exam with a board certified plastic surgeon is always the best way to fully assess your needs and address your concerns. Best of luck!

Assuming you’ve healed nicely from your nose job, you should be able to smoke marijuana by the 4-week mark. By this point, your nasal breathing should have returned to normal. Not to harsh your mellow, but keep in mind that marijuana smoke is stronger than tobacco smoke. If you were a frequent marijuana smoker prior to your rhinoplasty who has abstained for this long, the smoke may come as a shock to your system and cause some coughing or irritation. Easy does it.
