I enjoyed smoking right up to the day i was diagnosed with angina. I now vape.
Would i ever recommend vaping to a smoker - hell yes, every time.
Would i ever recommend vaping to a non smoker - never.
Breathing chemicals into your lungs is not a good idea. To me it's the lesser of two evils and i chose to vape rather than live my life with a constant mood altering craving. I believe that vaping is not risk free but is a better alternative to smoking.
I do take the moral high-ground here and am not ashamed to do so. I would gladly give my advice to anyone who asks for it but could never recommend vaping to a non smoker.
That doesn't make me anti vaping, i believe everyone has the right to do whatever they (legally) please. If non smokers want to vape then let them vape, but i will never ENCOURAGE non smokers to take up the habit.
