You know, there is something disturbing about this statement of yours - because we see in it the origin of the Drug War on the Citizenry. You: I am a pillar of the community! I forbid you from being self-indulgent! I will lock you up should you choose to be so! Your morality will be MY morality! To which I say: Fine. My opinion is - if people want to wipe themselves out with drugs, let them - because the safety of the community is not damaged by marginal druggies, unless of course they need to steal to buy expensive illegal drugs to support a habit, a need what would not exist if the market were eliminated - it is damaged by rightist corporate collectivists who want to force THEIR way of life on everyone else, peer into private lives, etc. etc. Your phrase "responsibility to the community" is a euphemism for state control of personal behavior.
