We got a lot of ''Nicotine threads'' might as well start another sub-forum ''Nicotine & Alcohol''.
If you go to the doctor, they will give you some pills, most likely an oral spray. Nasty cough? by this you mean mucus. Mucus it's dirt, this dirt is in your lungs. So your body wouldn't allow it, so you will spit. Nasty cough can be a cold. A lot actually but if you know your medical history then it's fine to assume it's mucus. Dry cough it's when there no mucus, might be a little cold. Keep in my mind that we are in 2020, this winter hasn't been as kinky as it should because it's the end of a decade.
