Hello everyone, my name is scott and I'm a college student. I'm 20 years old and I have been dipping for 3-4 years. Over the past month, I've had this on and off sore throat/sore in the back of my throat. It seems to act up when I stay up late or drink and smoke cigarettes. Other than those times, it doesn't really effect me. It started acting up today again and I looked in the mirror and saw a kind of sore looking thing in the back of my throat. It's kind of white. I'm scared it could be leukoplakia or something else. If anyone has had a similar experience and can shed some light on this issue, please do. Thanks!!
