JUUL is the poster child of the vaping industry with a $38 billion valuation and teenagers hooked on the product all over the world.
I have vaped for a few years and use 6mg nicotine content which is more than enough for me. At times even that amount can feel too much at the end of a day, but nothing compares to when I tried JUUL out of curiosity.
The experience was terrible. I felt quite ill after one pod and was surprised at just how strong the pods are. The following from Wikipedia explains the problem-
Each cartridge (called a JUULpod) contains about the same amount of nicotine as one pack of cigarettes and delivers approximately 200 puffs. The amount of nicotine in each cartridge—5 percent, or 59 mg/ml—is substantially more than the majority of e-cigarettes on the market.
These numbers are high, but it seems as though others are following the same route. Take the Vype ePen 3 as an example. The cartridges are 18mg strength, no alternatives, which is odd because you can buy Vype liquids in varying strengths and it is the Vype 6mg liquids that I currently use.
Pods are becoming more popular, despite the fact that they are more expensive than eLiquids, thanks to their simplicity and in some cases the cool factor, but it does seem as though the manufacturers are now pushing the addictiveness of nicotine in place of the traditional eCigarette line of ‘helping people to give up smoking’.
