Try not to worry too much , a small hole in your septum can remain trouble free, only you will know it’s there.
I have been an absolute **** as I had a huge hole in my nose and had an operation to repair it on the NHS, and what did I go and do a week after my op? Yup, stated snorting like I’d never snorted before and now have a hole big enough to put my finger through – I won’t get a second chance but all I can say is stop using now, the hole will grow much larger in a short space of time if you continue to snort coke. Even with a huge hole in my nose I continue to use as I’ve pretty much given up on life, don’t make the same mistakes as me
