No country can solve this problem alone.
The UN has agreed to hold a special session on drug law reform in 2016. It cannot come soon enough.
The current UN drugs conventions badly need revising. I want European countries to work together to agree a common position in favour of reform to take to that discussion in 2016.
The UK can lead the debate in Europe and Europe can lead the debate in the world.
But we must be prepared to start afresh with a new mindset and be prepared to do things differently.
Deputy Prime Minister Nick Clegg has called for the reform of Britain's drugs laws, accusing the Conservative party of "refusing to engage in a proper discussion about the drugs problem."
Writing in the Observer following a visit to Colombia, Mr Clegg described how the country is suffering from the "debilitating and socially corrosive effects" of drug use in Britain and Europe.
He said the Liberal Democrats are studying alternative ways to deal with the drugs problem and that he wanted to see an end to "the tradition where politicians only talk about drugs reform when they have left office because they fear the political consequences".

"I do not believe that classification stops people from taking drugs," she said.

If young people really thought for a moment that by getting used to taking Ketamine they would start to become incontinent, peeing blood and possibly eventually having their bladder replaced, and it will affect their sexual activity for the rest of their lives, then they would never take it.
Government drug advisers have recommended that Ketamine should be upgraded to a Class B drug because it can cause a "range of physical and psychological harms".

The drug advisory council said people as young as 20 are having to have their bladders removed due to consumption of the drug.
The drug has been used legitimately for more than 50 years, but has become a popular recreational drug, particularly among nightclub users and males aged 20 to 24 around the country, the council said.
Originally designed as an anaesthetic, often used on horses during veterinary surgery, ketamine was banned as a recreational drug in 2006.
An estimated 120,000 people misused the drug in England and Wales in the last year alone, figures suggest.
Party drug ketamine should be upgraded to a Class B substance, government advisers have said.
The Advisory Council on the Misuse of Drugs (ACMD) has recommended that the substance, known as "Special K" to its users, should be reclassified because of the physical and psychological harms it causes.
The drug is currently rated as Class C substance.
ACMD chairman, Professor Les Iversen, warned that ketamine users as young as 20 are having to have their bladders removed due to heavy consumption of the party drug.

Drivers in the UK are not tested for drugs on the side of the road, despite it being legal since 2003 as authorities have not found a device up to "British standards", toxicologist Dr Rob Tunbridge told ITV News.
In an Tonight investigation into drug driving, Mr Tunbridge said the Home Office has delayed implemented drug driving testing due to concerns over testing equipment.

The Home Office said they were committed to tackling drug driving and that they had approved a new drug testing equipment.
Responding to an ITV Tonight investigation looking into the risk drug drivers pose within the UK, a spokesperson said:
Drug driving devastates families and ruins lives. The government is committed to making our roads safer for everyone by equipping police so they can tackle those who drive after taking drugs.
We have already approved new drug testing equipment which is available for use at police stations and we aim to approve roadside drug testing devices as soon as possible.

In Germany, a country with a much smaller drug problem than the UK, police arrest 30,000 people per year for drug driving, whilst in the UK, the figure is considerably lower.
