Barney I agree with you mate. I started smoking when I was about 14, and had a 20-a-day habit for approximately 30+ years. I stopped a few years ago by using a rechargeable vape which could, literally, be a life saver. May have done too much damage, but anything that stops kids or anyone else starting is warranted.
The main mantra I repeated over and over to my kids (young adults now) was that within reason you do what you want to, but never, ever, start smoking.
