I have been smoking UNC (an off brand of it) for about 9 months, then I transitioned to the no nicotine version for 3 months. It's like I'm addicted to whatever is inside the disposable vaporizer besides the nicotine. It definitely has made my throat burn at month 6 and it's been on going. It definitely gave me tremors and friends and family have told me I have like this shaking, that's why I transitioned to the no nicotine, but it's no use. I also have a pins and needles feeling on my hands and feet at times. I don't know if it's interacting with my meds or not but I think it's because solely of the vaporizer. I tend to vape almost all day. I use cough drops to ease the throat pain. It's definitely not good for you but they say its the formaldehyde (in the anti-vape commercials) but I think it's something not even known yet.
