Hi there everyone. I started to use this product about a month ago . I actually gave up Smoking 3 years ago but got addicted to the Nicotine Gum. I thought I would start using the Vapour Cigarette to help me with my cravings still. Thought I will try and save my teeth as I've been chewing the gum for 3 years lol. Anyway I like the product very much but I get quite a bit of heart burn and my voice is sometimes Hoarse, I presume it's some sort of side effect from the vapour. Just wanting to know if anyone has had the same problems as me? My Daughter keeps saying to me that they are bad for people but there is no scientific evidence to prove this. Thanks for reading.
