Any Post Op MARIJUANA Users? in POST-Operation Weight Loss Surgery Q&A Posted January 8, 2017 Yeah the people I was with were experienced smokers with good weed. We smoked A LOT. My friend said it took her 4 or 5 times until she got high. The act of smoking didn't really appeal to me though, I would much rather eat a sundae hahah, that is my drug of choice... and sadly even the surgery didn't take that away I never used it before surgery, and tried it after and didn't get high at all. I was so disappointed. LolBut I don't think that is a reflection of the surgery, more a reflection of me being a first time userI've heard of this, how some people don't get stoned their first time and I always found it interesting. I got super stoned my first time and I just can't imagine how you wouldn't get stoned unless you didn't inhale. Its mind boggling.
