A new report by the U.K.’s “national centre of expertise on drugs and drug laws” says that drug decriminalization does not lead to an increase of drug use. In an article at Huffington Post, Columbia University epidemiologist Ernest Drucker argues that like alcohol prohibition, the “war on drugs” is doomed to fail and that prohibition measures like arrest and incarceration are forms of societal violence themselves.

The report, A Quiet Revolution: Drug Decriminalisation Policies in Practice Across the Globe, “looks at over 20 countries that have adopted some form of decriminalisation of drug possession, including some States that have only decriminalised cannabis possession.” The studies’ objective was to examine all existing research and attempt to establish whether communities that adopted decriminalization policies saw that the decision resulted in an uptick in drug use.
