Smoking 500 e-cigarettes a day is indeed too much. Although e-cigarettes have lower nicotine content than traditional tobacco, there is still a risk of addiction.
Generally speaking, you should not use e-cigarettes more than 5-6 times a day, and use them for no more than 10-15 minutes each time. Maintain moderate use to avoid overuse and addiction.
The specific amount of e-cigarettes that are suitable for smoking needs to be determined based on personal smoking and physical conditions.
If you are an old smoker, it is recommended to use about 80 puffs a day initially, and then gradually adjust according to your smoking situation. If you are a non-smoker, it is recommended to use it no more than 1-2 hours a day and no more than 10-15 minutes each time.
In short, the use of e-cigarettes should be controlled within a reasonable range to avoid overuse and addiction. At the same time, e-cigarettes should be used according to the instructions for use and must not be abused.
