The war on drugs was started by Richard Nixon, and over the years it has been both costly and ineffective. It has also contributed to the prison problem that the United States has. Currently, the United States has about 5% of the world's population, but 25% of the world's prison population. We incarcerate more people per capita than any other country, and yet in spite of this, the public's demand for various drugs has not abated. Additonally, the war on drugs has often become a war on blacks and other minorities in spite of the fact that these groups use drugs at rates that are either statistically equivalent or less than that of their white counterparts. And finally, the war on drugs has fostered and encouraged incredible abuse by law enforcement agencies. Below are a few documents that spell out what is happening.
