"One third of the drugs destined to international markets are transited through Iran," said Brigadier General Ismail Ahmadi-Moqaddam, secretary general of Iran's Drug Control Headquarters (DCH).
According to the official, "Iran is the best and the shortest transit route for drugs to world markets as Iran has long borders with Afghanistan, the main drug producer in the world."
"Iran seizes an average of three tons of drugs, including opium, morphine and heroin, every day," Ahmadi-Moqaddam said, adding that this indicated Iran "has an important role in campaign against drug trafficking" in the world.
