I had seen a thread a while back, something about Thyroid, in this forum. Mainly what my question is: can you start having thyroid problems after quitting smoking ciggerettes? Does vaping cause people to have thyroid problems? Like I said I know nothing about thyroid and have been experiencing some trouble while vaping and was going to see if I can maybe link it. Who knows, I probably don't have nothing but, its always good to make sure. Any information you can help provide for me about what causes thyroid and some symptoms would be awesome. Thanks for any help.
