10mg of vape is equivalent to 2 puffs of a cigarette.
Answer analysis: The key to this question is to understand the relationship between vape and the nicotine content of cigarettes.
The nicotine content of a vape is 10 mg, and the number of puffs of a cigarette is assumed to be 1 puff.
According to the meaning of the question, we need to find the nicotine content of a cigarette, and then find out how many puffs are equivalent to it based on the ratio of the nicotine content of the vape and the cigarette.
It is known that the nicotine content of a cigarette is 20 mg
Then, the ratio of nicotine content in vape and cigarettes is:
20 / 10 = 2
Therefore, the number of puffs equivalent to one cigarette is:
2 mouthfuls
So, 10 mg of vape is equivalent to 2 puffs of a cigarette.
