Hello, My name is Wayne I'm relatively new to vaping, I've been cig free since july 4th. I smoked and used the e cig for a year before that, the trick to vaping is not to do both, buy a e cig vape and never buy another pack. As for the guinea pig thing, yes vaping is somewhat experimental, however with juices the thing you want to stay away from is diacetyl and I can't remember the name of the other two chemicals, diacetyl can lead to disease that is refered to as popcorn lung, which is called that because a lot of popcorn workers got sick in the early 2000's from poor ventilation (I know this because I work at the very popcorn plant that got sued), MOST E juice brands claim not to use it. My advice on this front is make sure its a trustworthy brand, and if you think its better not to take a chance stay away from all cream or custard flavors they're the ones that contain the three problematic inhalants. There actually is a forum about them and what flavors may contain them on the forum somewhere. Do research, ask questions, the more you know the better. As for other articles I've myself heard of, The formaldehyde debate is stupid they don"t say what the e juice was and the heat they were using was highly unlikely for someone to be vaping that way. If your interested on youtube there is a video that debunks the whole thing by matt at suckmymod. Anyways if you're worried about the unknown of vaping then just use it as a crutch buy an ego and a cheap tank (I suggest a evod) help you with the withdraws. Then quit both, once you start buying mod's, drippers, RTA's, and batteries, it starts becoming a hobby which is much more addictive than the nicotine and the illusion its cheaper than smoking is gone . I hope I helped, and I hope you kick cigarettes for good.
