Two of my friends really want to use the E cig. but the throat hit is too much. I use 24 mg 555 and ry4. They both like them but can't inhale without coughing. I cut some to 12 with VG but they still can't take it. Any ideas on a way to give them good flavor and nicotene without as much throat hit? Whats funny is they can smoke a strong cigarette without coughing. Could it be the PG?
