I did read the rest of your post, but trimmed to just this, to say I agree. Smoking is a self indulgent self destructive habit that amounts to slowly committing suicide, among quite a few other other not so pleasant things, none of which are life affirming. Everything God has given us is good but man uses it to his destruction. The nicotine in cigarettes stimulate and release chemical messengers like epinephrine and dopamine that allow the smoker to relax, and also sharpens your brain and increases your alertness, but surely there are better ways to achieve the same effect?
