Ditto. Prolong usage of drugs alter the mind chemistry and creates addiction which benefits the vendor selling the drugs. Legalization does not eliminate these problems which start at the individual user level and eventually must be dealt with by society. Imagine during an emergency evacuation like Katrina level, the authorities must not only provide food, fuel and water during an evacuation, they must deal with drivers and evacuees who need their fix. Freedom can lead to enslavement by self inflicted stupidity (legalizing addictive drugs is one such stupidity) while Liberty is freedom bound by morality based on theology and past wisdom. Libertarians and liberals tend to mix them up, that is why communities dominated by liberalism/libertines end up with social problems.
Were the authorities providing tobacco and Jack Daniels to Katrina victims in the idiotic scenario you presented?
