Understand nicotine strength

Understanding nicotine strength may require some trial and error, but you will eventually get the hang of it. If you get an e-liquid that is too strong, you could make yourself sick. If you get too weak a nicotine e-liquid, you will be left wanting more and find cigarettes tempting once again.  Are you a heavy smoker that consumes more than one pack a day? If so, you should look at 18mg nicotine liquids. If you smoke 10 to 20 cigarettes a day, then 12mg would be more your speed. Otherwise, 3mg would be a good starting point. Remember, if your goal is to wean yourself off nicotine, you can always go down a strength level over time.
