"I" know very little about???!!!! Heh! Ok! (You don't know much about us in here do you?!)
To know the medical problems of smoking, then to work to promote the death of other people is hardly something one would brag about. You are so overly concerned about your 'rights'; you are oblivious to the fact that you are killing yourself, and aiding in killing others. Now, I fancy myself a libertarian; or bluntly "I don't care what you do to yourself, you want Hashish - fine, Cocaine - fine, Cigarettes - fine". But, one would expect at a minimum one would not be in denial about what you are doing to yourself.
If your stance was "I know that cigarettes will increase my likelihood of developing lung cancer, emphysema, heart, liver and kidney disease, as well as a host of other problems; at least I could respect your decision". But simply denying these dangers exist either leads me to believe you are emotionally disturbed, or very naive'.
When the time comes when you do succumb to the effects of cigarettes; and the odds are high that you will, as you lay in the hospital saying goodbye to loved ones, just think of the scores of others you helped do the same. I'm sure you will be very proud of your accomplishements at that point in time.
