The full recovery process after the rhinoplasty procedure takes up to one full year. It is great you did not smoke during all 8 months giving a chance for you nose to heal properly. At this stage smoking should not compromise your results. Of course you have to realize that smoking is never a good choice for your health.
I Started Smoking 8 Months After Nose Job. Will It Change Appearance of my Nose?
Smoking immediately after a Rhinoplasty, IMHO, may affect the final results but not if you started 8 months post op. At that time after the nasal surgery, the nose is mostly, if not completely healed so smoking would not affect the final results.
