Gharibabadi made the remarks in a letter to Executive Director of the United Nations Office on Drugs and Crime (UNODC) Ghada Fathi Waly.
He called on the UN and its member states to practice their responsibility to recognize and support Iran’s activities in this fight.
The Iranian envoy noted that seizure of illicit drugs in Iran topped by 20% last year in comparison to the previous year.
On May 19, Iranian anti-narcotics police seized over one ton of narcotics as they broke up a band of smugglers in the Southeastern province of Sistan and Baluchestan.
Police Chief of Sistan and Balouchestan Second Brigadier General Mohammad Ghanbari said that the anti-narcotic forces captured six drug smugglers in the border town of Hirmand.
He noted that the operation led to the discovery of 1,117 kilograms of different drugs, including 1,059kg of opium, 17.6kg of heroin and 39.5kg of meth.
According to a relevant report released on May 13, Iranian anti-narcotics police captured over 22 tons of illicit drugs in the country just in a week as they succeeded to clamp down on traffickers and cut the narcotics transit chain, an official said.
International Deputy of Iran Drug Control Headquarters Nasser Aslani said that 22,800 kilograms of narcotics have been confiscated in different parts of the country during the last week.
“The figure indicates a 49% rise compared to the corresponding period last year,” Aslani added.
The consignment consisted of 19,387 kg of opium, 2,964 kg of hashish, 235 kg of heroin, 84 kg of crystal, 48 kg of grass, 26 morphine, and 56 kg of other types of drugs, he said.
