How can I be a healthy smoker?

I'm curious, how can someone who smokes regularly still strive for a healthy lifestyle? Is it even possible to be a healthy smoker, or is that an oxymoron? I understand the dangers of smoking and the negative impact it has on health, but for those who find it difficult to quit, what steps can they take to mitigate the harm? Is it about choosing the right type of cigarettes, limiting the number smoked per day, or perhaps incorporating certain lifestyle changes? I'm looking for practical advice that can help smokers reduce the risks associated with their habit while still enjoying it, if that's even a feasible goal.
