In 1971, Richard Nixon declared drug abuse “public enemy number one”. This marked the start of the “War on Drugs”, a global escalation in police and military efforts to crack down on drug users and the illicit drug trade.
In the past five decades, three things have become clear. First, the War on Drugs has not been won. Although a 1998 UN special session aimed to create “a drug-free world” by 2008, illicit drugs are still plainly available today in nearly every town and city in the world. In fact, a 2013 paper in the British Medical Journal found that, between 1990 and 2007, the prices of heroin, cocaine and cannabis in the US dropped by over 80 per cent while their purity increased. The story was similar for Europe and Australia.
