There is no accurate data on how many puffs 1 ml of e-liquid can take.
The nicotine content of vape juice is different, and the number of puffs per milliliter of vape juice will also be different.
For example, the nicotine content of a cigarette ranges from 0.5 mg to 2.4 mg, and one cigarette can last about 10 to 15 puffs.
Therefore, it is impossible to give an accurate answer and can only be judged based on the actual situation of the individual.
