Report reveals weaknesses in 'war on drugs'
A report is warning the so-called international "war on drugs" is failing to curb supply.
Researchers have said that despite increased funding being ploughed into law enforcement, illegal substances are now cheaper and purer than 20 years ago.
The report's author said that we should consider drug use a public health issue rather than a criminal justice issue.
The United Nations recently estimated that the global drugs trade is worth at least US $260bn every year.
