I’m sure vaping isn’t risk free, but I’ve been cigarette free for many years, I do vape a lot more than I used to smoke but on balance I’m sure it’s the lesser of two evils, one thing about the juice though, there are a awful lot of cheap unregulated juice sold cheaply that I’m sure has been mixed who knows where containing who knows what, always buy decent quality juice from a retail shop and not the market or car boot sales.
