Vaping started as a way for people to quit smoking but came a long way since then. When we started vaping, the market was limited to basic tobacco, mint, and fruit e-liquids with nicotine strengths of up to 36mg/ml being vaped on leaking vape pens. The industry was growing, more and more people were successfully quitting smoking with the help of their trusty e-cigarette. We have seen vaping getting regulated – limiting nicotine strengths, e-liquid bottle sizes, and tank capacities, forbidding online sales of nicotine liquids. Tobacco Products Directive hit us hard, especially the ones trying to quit deadly cigarettes via vaping. Limiting nicotine strengths in e-liquids has caused a lot of people to revert back to smoking. E-liquids use freebase nicotine, which at 20 mg/ml is not enough for some vapers. The nicotine hit of freebase nicotine shot is not comparable to a regular cigarette while the throat hit is too harsh on more powerful e-cigarettes. The financial aspect of vaping suffered as well. Since you could not legally purchase any nicotine liquids in bottles bigger than 10ml, you could not manufacture your own e-liquids at reasonable prices. You couldn’t even get a bigger, more economical bottle of your favourite e-liquid from your local vape shop. E-liquids became too expensive and not strong enough to convince people to start vaping and quit smoking. Luckily, with the introduction of TPD, vaping industry created shortfill e-liquids. Shortfills are concentrated, nicotine free e-liquids. To prepare shortfill for vaping, add a 10ml nicotine shot and shake vigorously to obtain a ready to vape e-liquid. This solved the 10ml bottle issue but greatly limited the nicotine levels available to vapers. The “nic shot” (or nicshot) is also limited by the TPD in terms of capacity and nicotine levels. This last hurdle has been defeated with the introduction of nicotine salts.
