Do doctors do drug screening before surgery?

Tests other than for nicotine and pregnancy are not routine before elective plastic surgery, but if you do use drugs it is very important that you discuss this with your plastic surgeon and your anesthesia provider. Your medical records are confidential. 

Pre operative testing will vary by surgeon. Some surgeons will test for nicotine prior to surgery, while others do not. It is vital for your safety to be open and honest with your surgeon about medication use as well as any recreational drug use. Failure to do so can put you at risk during surgery.

Some do and some don't. If you are having surgery, please avoid any recreational drugs. Your liver has to handle everything it is given and you will receive a fair amount with anesthesia. Also, you do not want to have a bad reaction with your drugs.
