The amount of nicotine required for e-liquid preparation depends on the type of cartridge.
Answer analysis:
Taking a conventional 1.8ml cigarette cartridge with a nicotine content of 3% as an example, the nicotine content of each cartridge is 43mg; if it is a tobacco-flavored 5% nicotine content currently on the market, the nicotine content of each cartridge is 72mg.
The nicotine content required for all e-liquid formulations depends on the specific needs of the formulation and product.
Generally speaking, the nicotine content in e-cigarette liquid is within a certain range and can be adjusted according to the needs of smokers.
For example, the European Union stipulates that the nicotine content in e-cigarette products shall not exceed 20 mg/ml. The quality of domestic e-cigarette products is uneven, the nicotine content in the e-liquid fluctuates widely, and the labeled nicotine content is significantly different from the actual content.
