Quick question to all- I've been a long time user of smokeless tobacco (30yrs) and have recently heard of a new thing called "Vaping" as an alternative to cigs and snuff. Anyone know about this.? Supposedly the product only has 4 ingredients - propylene glycol, vegetable glycerin, natural flavors and nicotine. I know anything other than air going to the lungs is bad just wondering if this might be a safer alternative than the dip.
