ARE THERE ANY ARGUMENTS AGAINST SMOKING?

All I have heard comes from the media, yet there is no credible source that categorizes smokers into moderate smokers, heavy smokers and statistics regarding their lifestyle, health, etc. It seems that there is no valid argument against smoking. Who is benefiting from anti smoking lobbies?why? and why anti smokers do not believe in freedom of choice and act in a hypocritical manner when it comes to the freedom of choice to smoke?
