I have seen a couple questions regarding this issue, I have been a recreational cocaine user for 4 years , usually couple lines every other weekend, No i am not addicted, yes i can and will stop, There are no guidelines for this as far as how much and how long you need to use for a hole to form, But i know i will refuse to get help as far as a doctor is consernered.. Does a small hole heal? and what am i looking at if i do not seek help? I am not looking for guesing games i am looking for someone who has been through this.... Please....:)
