I've been vaping for 3 weeks now still on cigs at certain times of the day at work as vaping is not allowed in my country. So before work, lunch n after work I go for analogues. The rest of the time I'm vaping. Recently I've been chain vaping and think I have developed a cough. Wondering if it is from the cigs which is 3 a day or the over vaping. Any views would help.
