Do doctors do drug screening before surgery?

I do not drug screen patients except for nicotine. Different doctors might have different requirements before surgery.Best of luck.Dr. ALDO 

Thanks for your question.  I can't speak for others but I don't do drug screening.  The doctor-patient relationship is built on trust and confidentiality, so I trust my patients to provide accurate information.  Technically a person could decide not to tell me all sorts of important information, not just the drugs they are taking.  For your safety I'd suggest telling your surgeon your complete medical history, including recreational and medicinal drugs you use.
