Honestly don't even know where to start with your post. Has way too many fallacies.
Sec and Vaping? Lol nope.
Overpriced? It's actually on the cheaper end. Own a $400 piece. But the limitless is innovative. First of its kind really. Binary eliquid is very good and very popular.
And actually there are no studies linking harmful chemicals. 95% safer than smoking and when used properly zero harmful effects. Studies actually show its more harmful to inhale city air than Vaping.
The study you may be citing was proven a complete fallacy as the testing standards would never be used by a consumer.
