Here is snip from an article he wrote in 2007 which was published in The Daily Mail:
Britain is protecting the biggest heroin crop of all timeby Craig Murray (former British Ambassador to Uzbekistan)

Our economic achievement in Afghanistan goes well beyond the simple production of raw opium. In fact Afghanistan no longer exports much raw opium at all. It has succeeded in what our international aid efforts urge every developing country to do. Afghanistan has gone into manufacturing and 'value-added' operations.
It now exports not opium, but heroin. Opium is converted into heroin on an industrial scale, not in kitchens but in factories. Millions of gallons of the chemicals needed for this process are shipped into Afghanistan by tanker. The tankers and bulk opium lorries on the way to the factories share the roads, improved by American aid, with Nato troops.
How can this have happened, and on this scale? The answer is simple. The four largest players in the heroin business are all senior members of the Afghan government, the government that our soldiers are fighting and dying to protect.
When we attacked Afghanistan, America bombed from the air while the CIA paid, armed and equipped the dispirited warlord drug barons, especially those grouped in the Northern Alliance, to do the ground occupation. We bombed the Taliban and their allies into submission, while the warlords moved in to claim the spoils. Then we made them ministers.
President Karzai is a good man. He has never had an opponent killed, which may not sound like much but is highly unusual in this region and possibly unique in an Afghan leader. But nobody really believes he is running the country. He asked America to stop its recent bombing campaign in the south because it was leading to an increase in support for the Taliban. The United States simply ignored him. Above all, he has no control at all over the warlords among his ministers and governors, each of whom runs his own kingdom and whose primary concern is self-enrichment through heroin.
