Our e-liquids come in 6 nicotine levels (0mg, 3mg, 6mg, 12mg, 18mg, 24mg). They have been specifically made for smokers by (ex)smokers, so all of them have the throat hit that a smoker wants (even the nicotine free e juice).
The higher the nicotine level that you choose the more throat hit you will get. If you smoked a strong cigarette or cigar you should be choosing a higher nicotine level like 18-24mg. If you smoked lights, something more along the 6-12mg would be more suitable. Our most popular nicotine level is the 12mg.
