Cocaine before surgery - will my surgeon cancel?

Do not proceed with your surgery as you are at marked increased risks of complications from both recent use of cocaine and ongoing nicotine use. You need to have medical clearance at a minimum from the anesthesiologist who needs to know of this history, and need to be off both cocaine and nicotine for months prior to elective surgery. I also strongly recommend that you are candid with your surgeon and never hold back medical details that could affect your health. There is a sacred patient physician relationship restricting him from sharing any of your medical information

I strongly recommend being honest with your plastic surgeon. Patient safety should always come first. Best of luck, 

Be sincere with your surgeon. Cocaine can have some potential risk, especially on the heart rhythm. The anesthesiologist also needs to be aware of that.
