"The impact of the drug war has been astounding.
In less than thirty years, the US penal population exploded from around 300,000 to more than 2 million, with drug convictions accounting for the majority of the increase.
The US now has the highest rate of incarceration in the world, dwarfing the rates of nearly every developed country, even surpassing those in highly repressive regimes like Russia, China, and Iran.
In Germany, 93 people are in prison for every 100,000 adults and children. In the US, the rate is roughly eight times that, or 750 per 100,000 (Alexander, 2012, p.6)."
