7/1/97 ALMATY, Kazakhstan (Reuter) Kazakhstan has become caught up in the international drug trade and the former Soviet republic has the largest potential in the world for producing cannabis, U.N. and Kazakh officials said Tuesday. ``The problem of cannabis is extremely significant for Kazakhstan, because there is no larger potential for its production than in Kazakhstan,'' Herbert Behrstock, U.N. Resident Coordinator in Kazakhstan, told a news conference. Presenting the latest U.N. drug report, Behrstock said that cannabis produced in large quantities across Central Asia remains the most used drug in the world. ``This is a warning for all of us,'' he said. Nurlan Abdirov, head of Kazakhstan's recently formed State Drug Control Committee, said cannabis was grown in huge amounts in the vast Chu Valley which Kazakhstan shares with Kyrgyzstan. Abdirov said cannabis is grown on at least 138,000 hectars in Kazakhstan and on a further 60,000 hectars in Kyrgyzstan. A hectar is roughly 2.5 acres. ``But Kazakhstan has also become a transit country in the international drug trade,'' he told the same news conference. Abdirov said that narcotics mostly cheap raw opium from Afghanistan, Pakistan and Iran are transported across Kazakh territory to Russia and then further to Europe. The borders of Kazakhstan a huge country of rolling steppes five times the size of France but with a population of just 16.7 million people pose little obstacle to international drug traders, he said.
