I had a rhinoplasty in 2009. Since then I've used cocaine throughout the years, not all the time but enough to have potentially caused some damage. It is extremely stupid for me to have done this. It also like the septum is thin and the nasal mucosa is thinner on one side. Also because I'll need grafts, I'll assume that it would be harvested from the cartilage. It is recommended to have a revision after cocaine use (not substantial but may have been enough to cause thinning of the layers)
