I know when I had my problems the docs asked if I had ever vaped. I told them about doing it for a few months while I stopped smoking. One of the docs replied that only doing it a few months may have saved my life. If you vape, be cautious and if you start serious coughing or having breathing problems, get your a$$ to the doctor.
