Wow, that is so weird. I use marijuana for anxiety/depression, and I was honest with my surgeon as well as the dr who did my psych evaluation about it. The only time they advised me to stop was the 30 days pre op when they wanted me to stop all other meds and prepare for surgery, liquid diet, and all that Jazz. As far as I know I wasn’t “drug-tested” because surely would’ve been positive for THC. I live in VA where marijuana is decriminalized but not legal. People don’t really frown upon it here.
