I'm 33 - from the age of 17/18, I come from a family of smokes so thought I was doing well but 'only' socially smoking on nights out, perhaps once a month or so, maybe twice. Continued this until around 3 years ago when I discovered vaping. Thought it would be a less toxic alternative but it is miles and miles more addictive and have found myself wanting it in the daytime, every day. Would I be unreasonable to revert back to smoking far more infrequently with its known health implications, rather than continue vaping with its unknown long term effects?
To add - please don't say 'the healthiest choice would be to not do either' - obviously. I, as many have throughout the millennia, enjoy a vice or two during their short time on earth, as long as it most likely won't completely decimate their life.
