I messed up this past weekend. I had a l5s1 fusion on mar 30th this year with bmp and instrumentation. It was done through by back. I used to be chewing tobacco user until i heard the effect it has on a fusion. I quit one week before surgery and have not used once untio this last weekend. I am 3 months out and chewed a can. I am so upset with myself, and am not going to do it again. My question is will I be alright or did I just screw up the fusion? I am so stressed out about this situation answers would be greatly appreciated. Thanks everybody.
