. I know this a pretty old post, but I found it a couple of days ago. I'm currently a nursing student who is in the process of getting cleared for the VSG. I medicate using MJ as well for the same reasons and lower back pain. I was told by my surgeon that I should stop usage 6 weeks before surgery and to no longer smoke afterwards(just edibles). I want to know your experience with smoking after surgery & how you are passing drug tests as a nurse.
