The highest nicotine vape juice available on the market is usually labeled as "extra-strength" or "maximum-strength" and typically contains between 24mg/mL and 36mg/mL of nicotine. This is significantly higher than the standard strength, which ranges from 3mg/mL to 18mg/mL.
When choosing the highest nicotine vape juice, it's important to consider the type of device you are using. Some devices are not capable of producing enough vapor to effectively deliver higher concentrations of nicotine. For example, a low-wattage device may be fine for a 3mg/mL e-liquid, but will not be able to deliver the same amount of nicotine as a higher wattage device.
It's also important to consider your own nicotine tolerance. If you are new to vaping, it's best to start with a lower nicotine strength and gradually increase it over time as your body adjusts. If you are an experienced vaper, you may be able to handle higher nicotine concentrations, but it's still important to start with a lower strength and work your way up.
Finally, it's important to note that higher nicotine concentrations can be harsh on the throat and may cause irritation. If you experience any discomfort, it's best to reduce the nicotine strength of your e-liquid.
Overall, the highest nicotine vape juice on the market typically contains between 24mg/mL and 36mg/mL of nicotine. However, it's important to consider your own nicotine tolerance, the type of device you are using, and the potential for throat irritation when choosing the right nicotine strength for you.
