Snuff (chewing tobacco pouches) a day after surgery?

You should not have any sort of nicotine during the healing process, for at least 4 weeks following surgery.  This can cause a lot of healing delays.  After having a major surgery like that you want to allow you body to heal completely and properly. 

Tobacco products are better avoided in the peri-operative period. Smoking could be worse but nicotine could still affect wound healing/
