There would be realms where you are free to engage in whatever pleasures you like and as like attracts like be in the company of like minded souls. But you're not static and neither is the afterlife as some mistakenly believe, changing is always an option.
My suggestion Chumley to you as I've stated in the thread about 'We're all going to hell' is drop the whole obsession you have with 'literal christianity' (the need to constantly mention in every second post) and focus on self empowerment. You can't control the choices of others and as much as it irks us you can't stop George W. Bush from muttering his religious babble 

If smoking makes you happy then its your choice you shouldn't change because someone else tells you to but if you see that a better choice would be to quit then do it for yourself. Its up to you in the end and it seems like you're doing a good thing by giving up smoking to improve your health and quite probably increase your life span.

Hi Chumley i wish you well in giving up,my mum has throat cancer which the doctors say that she should never smoke again because if she does the cancer would definetly come back after it is cured,which the doctors are very comfident that mums cancer will be cured,so my mum has definetly given up now.

But there is this man that goes through to the hospital with her in a hospital car and he has the same cancer as my mum but he has never smoked in his life,it is good to give it up but i think whether you smoke or not if you are going to get cancer you will get it even if your the healthiest person in the world.
