Addiction research lab Recovery Brands has created an interactive map to better understand addiction as a global problem, from the amount of drug users to the number of those who have died from an overdose.
Using data from the United Nations Office for Drug and Crime, drugs are split into several different categories: cannabis, cocaine, acid, opioids (heroin, opium and pharmaceutical opioids), tranquilizers and sedatives (benzodiazepines and barbiturates) and amphetamines.
War on drugs?
The records for drug-addiction treatment are Iran and New Zealand. Of the Iranian population, 1 to 3% – meaning 14,192 people per million inhabitants – are being treated for opiate addiction, primarily heroin and methamphetamines.
The border with Afghanistan, the world's biggest producer of opium, makes Iran the ideal region for trafficking drugs, or getting your hands on a bit of heroin.
As for New Zealand, the peace pipe proves the most popular: 14.6% of the population are cannabis users. Iceland is, sadly, the country that counts the most deaths by overdose per capita, at 212 estimated deaths per one million inhabitants.
According to another graphic by the same research lab, Scotland is the most cocaine-addicted country, coming in just slightly ahead of Spain and the United States. And with the most opioid users – in terms of heroin or pharmaceutical use – and the most cannabis users worldwide after Iceland, it would seem the US is having trouble leading its "war on drugs".
Interestingly, Colombia, the world's biggest cocaine producer and exporter, treats the most amount of people for addiction to... cannabis.
According to the United Nation's Office for Drug and Crime figures dating from 2015, recreational and pharmaceutical cannabis use is on the rise, while cocaine consumption is going down. Meanwhile, heroin and opium user rates are more or less static.
The same study states that 5% of those aged from 15 to 64 across the world – meaning around 246 million people – admit to having used illegal substances in 2013.
