With origins in bigotry and racism, and sustained by the use of force, drug prohibition is a violation of the most basic human rights. Prohibition affects drug usage for the worse. Drug users are worse off under prohibition. Although intended to protect people from drugs, prohibition worsens the situation of drug users, increasing criminality and health problems. Drug sellers are more dangerous under prohibition.
Prohibition enriches the worst criminals and leads to more violence.
Prohibition corrupts the judicial system. Due to prohibition's nature, drug enforcement inevitably leads to overburdened courts and jails, fewer resources devoted against violent crime, and corruption at all levels. Prohibition leads to destruction of other liberties. Faced with failure, prohibitionists seek more and more infringements of individual liberties, from restricting speech to banning guns, from more intrusive searches to higher taxes. Prohibition deprives us of beneficial drug use.
