How can anyone make anyone do anything unless its blackmail.
It is unfortunate he/she is smoking, and that you have to 'take it it'.He/she either:
Does not understand the seriousness behind it, and the fact that the consequences are irreversible.or
He/she really does not have a deep awareness of self and self love.The only real solutions, I think have to correspond and relate to those two.If you have them both, then you really, just wouldn't smoke.Obviously self awareness, and self love must come first. But try not to confuse this self awareness with boastfulness and ego.
Such awareness can only express the good, unselfish potential which is deeply rooted and natural, but well blocked, distracted and hidden from in the vanity of daily life.
One would have to call into question their own existence, as well as everything else, and develop an intellectual understanding, which becomes intuitive, and natural.
And to attain happiness through their own means, without harming or comprising things around them.
Sounds very philosophically annoying, no? I know, but that is the truth.And when one knows what tobacco does to the lungs, with this strong awareness- the desire to actually stop, as opposed to just stopping takes into effect, and makes it better. Self attitude and drive is key. PulchraMors is spot on with this.To help with that on the not so good days (as you imagine, we wouldn't be feeling so oh spectacular nearly all the time), perhaps, fruit tobacco as a substitute- (it might not do because it is vapour and not smoke, which is a sensation smokers get addicted to) , or at least ones without all the other synthetic chemicals), could help out. I don't know if electric cigs works, but some people like it- others don't- it depends.Most importantly, it has to be his/her choice- a strong, meaningful one. A solid one. A real attempt. From his/her own person. It is the only way.Hope this helps a little.
