What nicotine strengths is the Hangsen E-liquid 20 x 10ml pack available in?

The Hangsen E-liquid 20 x 10ml pack is available in nicotine strengths of 0mg, 3mg, 6mg, 12mg and 18mg. If you’re trying to give up nicotine, gradually lowering the strength of your e-liquid is a great way to taper off without going cold turkey. This is because you can still vape the same amount (in terms of puffs) while reducing the actual amount of nicotine you’re taking in.
