I am 22. I first tried coke in December of last year. From December to march I have done it about 5 or six times. The first week of March was the last time I did it. I am done, and am not doing it ever again. My nose hairs towards the back of my nose have gone away. I only have the hairs closest to the outside of my nose. I also noticed red in the back of my nose. And it's a lil sinked in, which I'm not sure if it is supposed to be like that or it was caused by the coke. What I would like to know is if a whole in my nose can still be formed even if I have stopped? Also, if my nose hairs will grow back?
