3 MG/ML (milligrams PER millilitre) is a very low amount per dosage, I would not be concerned about this if you are an adult and you want to
vape, just keep in mind nicotine is addictive, but so is caffeine, and in these dosages administered properly by using a subtank or similar, is amongst the same nicotine levels we see in Potatoes, Tomatoes, Cauliflower, ect. So no evidence has been presented that could indicate the nicotine at this level being a health concern, but I would suggest to just not vape if you are not a smoker to begin with, that is not what we all intended
vaping to be, and the data shows that you are in the 1% of
vaping users.
