I have surgery scheduled for tomorrow afternoon, I smoke marijuana quite regularly (and that's it, no cigarettes or other medication --and of course no other drugs), although I haven't since last night, will I be ok during my surgery? I am worried about discussing this with the anesthesiologist for fear of them cancelling my surgery and of course, the brow beating. From what I understand, I should only be under for about fifteen minutes (I am having a D&C and endometrial ablation). I am worried that I might not wake up. I did have a cone biopsy under general anesthesia a few months ago and was ok, I'm just a ball of antsy nerves tonight.
