weight and told me she has been sniffing 20 mgs of Ritalin every morning for a couple months. I obv know this is terrible and told her how bad it is for her heart, but does anyone know any other effects or anything i can tell her to scare her away from doing this anymore? Can sniffing Ritalin burn a hole in her nose? I told her it would but she said thats only happens to people who use cocaine for long periods of time. Help
