In the 1990s - the period of the greatest escalation of the drug war - nearly 80 percent of the increase in drug arrests was for marijuana possession, a drug less harmful than alcohol or tobacco and at least, if not more, prevalent in middle class white neighborhoods and college campuses as it is in the 'hood.

The bigger picture is that over the last 30 years, we have spent $1 trillion waging a drug war that has failed in any meaningful way to reduce drug addiction or abuse, and yet has siphoned an enormous amount of resources away from other public services, especially education.

The fact that people of all colors have been ensnared by the drug war helps to preserve the system as a whole from serious critique, as it creates the impression - at a glance - that the war is being waged in an unbiased manner, even when nothing could be further from the truth.

The system functioned relatively automatically, and the prevailing system of racial meanings, identities, and ideologies already seemed natural. Ninety percent of those admitted to prison for drug offenses in many states were Black or Latino, yet the mass incarceration of communities of color was explained in race-neutral terms, an adaptation to the needs and demands of the current political climate.

Nationwide, 1 in 3 black men can expect to serve time behind bars, but the rates are far higher in segregated and impoverished black communities.

Prison guard unions have become the powerful political forces in some states, particularly California.

Mandatory minimum sentences give no discretion to judges about the amount of time that the person should receive once a guilty verdict is rendered. Harsh mandatory minimum sentences for drug offenses were passed by Congress in the 1980s as part of the war on drugs and the "get tough" movement, sentences that have helped to fuel our nation's prison boom and have also greatly aggravated racial disparities, particularly in the application of mandatory minimum sentences for crack cocaine.
