I smoke 2 packs of cigarettes a day and I don't cough when I inhale a cigarette. But every time I take a hit off this e-cig, I'm coughing up a lung. I thought the 36 mg cartridge was too strong for me, so I took it out and tried to inhale with no cartridge. Same cough. Feels like I took a huge deep inhale with a strong cigarette. When I take the mouthpiece off, it reeks of menthol. Could it be that there's still menthol on the atomizer and that's still too strong for me? I just don't get it. I do smoke lights, but I don't cough up a lung when I inhale. Am I doing something wrong?
