I had a spinal fusion L3/L4 back in Oct. 2011. I was vaping for 3 years prior and didn't stop before the surgery nor have I stopped since. I had some pain relief but gained different pains on the other side now when I bend or twist in certain ways. I have been reading some real scary things lately about failed spinal fusion rates of smokers and it's attributed to nicotine specifically. None of the doctors that I have seen have told me that I'm not fusing yet but I don't feel like I am. It's kind of late to go 0 nic now almost 6 months later (or maybe not...), I really worried that I've seriously hurt my recovery chances. I just need to talk with anyone who has gone through or is going through a similar situation. Still haven't told any of my doc's about vaping because I know that 1st thing they will say is quit or go 0 nic. I've been investigating a bone stimulator because a lot of doctors use those for back surgery patients that smoke. All help and thoughts are appreciated.
