Smoking doesn't do any harm, that's just the anti-tobacco lobby crying wolf yet again, bloody peasants. In fact you can acheive good health with a good smoking regiment, at least once in the morning, after each and every meal and once before you sleep.
It's hard at first as anything good can be. Initially you feel woozy and may gag but if you do it for 8 weeks and then stop smoking for 3 weeks (to under-stimulate the lungs lest they become too powerful for your diaphragm, akin to taking time off of the bicycle before a big race) you will be amazed at how good you feel at the end of those 3 weeks before you begin your next smoking regiment.
