I for one feel that someone should not knowingly be injesting any substance into their body they know to be harmful. My personal morals tell me that my body is to be treated with the utmost respect and I avoid unethical behaviors such as smoking, drinking, eating fast food etc. Anyone who doesn't treat their body with the same level of respect that I uphold mine to, is in my eyes an unethical person. However, their body is their body and the use of those substances are legal within the law. If someone where to be so thoughtless as to jeopordize my health then I would let them have it. If its legal and not effecting me the have at it. Might not be fair that people such as myself who look after ourselves have our tax dollars being spent on lung cancer clinics but I suppose paying a little in taxes is a whole lot better than dying before my time.
Marijauna is a nother issue. It's Illegal. Doesn't matter if it is decriminalized, it is still prohibited under law. Kinda similar to flossing if you think about it. Illegal, but still tollerated to a certain extent under the law. Some people love it, some people are dead against it. Interesting....
Now that I've spoken my bit, I'd like to say that I'm not a total nazi. I don't smoke anything, drink any caffine, rarely eat junkfood and avoid for the most part over the counter drugs. I have been known to have the odd brew but thats about it. The whole reason for the above speal is that this thread reeks of ethnocentrism and is just putting one camp of people against the other.
