ISLAMABAD - The unabated drug trafficking from Afghanistan to neighbouring states with the alleged involvement of some influential Afghan government elites is one of the major constraints contributing to Afghanistans strained ties with former Soviet Republics and the United Nations. Diplomatic representative of a credible former Soviet Republic has shared with TheNation that illicit drug trade exceeding $8 billion annually takes place among Afghanistan, Iran, Pakistan and the country he represents. According to the diplomat, to curb this practice, anti-drug trafficking agreements had been signed with Iran and Pakistan. One such agreement that was signed in summer last year with Pakistans Anti-Narcotic Force (ANF) by the country in question has not come into effect till date due to its non-ratification by Pakistani Parliament. On the other hand, the diplomatic efforts to take up anti-drug trafficking drive with Afghan government have gone futile due to the reluctance of Afghan government to sign binding treaties or agreements at diplomatic level, says the diplomat. The reason of the Afghan governments apathy, as the diplomatic official sees it, has much to do with the involvement of some local influential persons who have grabbed top slots in the Government. The same opinion is shared by sources in a UN agency who believe that the drug trafficking goes unchecked in Afghanistan under the patronage of some family members of a top ruling Afghan government functionary whose stepbrother is believed to run an underworld drug trafficking mafia in Afghanistan. In October last year, a report of United Nations Office on Crime and Drugs (UNODC) had revealed about Afghanistans monopoly in worlds global opium poppy cultivation with 92 percent of raw material for heroin cultivated in Afghanistan. In another subsequent report, UNODC made public that 900 tonnes of opium and 375 tonnes of heroin were trafficked from Afghanistan to Pakistan, Iran, India, Russia, China and numerous Central European countries. Proving to be final nail in the coffin, a latest report by the same UN agency on cannabis released in last March unearthed that Afghanistan was the worlds largest producer of cannabis in addition to being the worlds largest producer of opium. The additional findings indicate that over 10,000 to 24,000 cannabis plant are grown in Afghanistan annually. In the aftermath of these reports, UN in Afghanistan has received threats reportedly from Afghan government. Furthermore, one-year extension granted to UN missions in Afghanistan by the Secretary General Ban-Ki Moon has not gone well with Afghan government ahead of upcoming parliamentary elections.
