The Affects of JUULing..

So JUULS have now been out for awhile now and have had major success, I wanted to look back on it and see all my steemer's thoughts. At the beginning of last summer (2017) I was going on vacation to San Diego where my friend lived, and from there to Cancun. I got there and my friend told me about this thing called a JUUL that he knew I'd be hooked on (knows me to well :( . When I got to San Diego I went to every vape/smoke shop in the area to get my hands one, starting off with no luck. One store I went to said they were getting 10 units the next day, I went down there at the time he told me and there was only one left! Anyways to make a long story short(er) I've been completely addicted to mine ever since the day I got. Prior to the JUUL I was never a guy who "VAPED", just smoked tobacco on here and there. I got on the train much earlier before the fad even reached my home of Washington State. Anyways, I've been rippin it for a year now and feel somewhat burnt out and tired from it? Is there any other JUUL smokers out there that have felt any long term affects? There is little to no research on vaping and JUULs more specifically, and I feel like I feel different since starting it even though I can't pinpoint what. Let me know in the comments how your experience has been !
I know someones gonna tell me to quit smoking because its obviously bad so save it.
