Hey guys. 
 
I'm from Ontario, Canada. 
 (If these questions have been awnsered already, I'm sorry. My internet is slow.) 
 
I'm a track runner and singer, meaning I've never smoked in my life. 
 
Yet, I want to try an e-cig. 
 
I was planning on buying a "Happy 010 mega". Its a Joye 510 clone, which is only like $15 for the starter kit. (With two carts, atomizer, charger and manual mega battery). 
 
These don't have a light on the end, so I can vape in stealth. aha. 
 
 
But enough about that.  
 
I don't ever plan to use nicotine, so I'd be just using the 0mg juices. (mmm redbull) 
 
With that said, 
 
Are e-cigarettes safe to use, if I do not use nicotine juices? (I'd just be using 0mg juice, as I've stated.).  
 
 
**By "safe", I am referring to; if the e-cigarette would be hazardous to my health in ANY way. [such as vapor being unhealthy etc]).
