About 1,500 high-level representatives are expected in Vienna on Thursday for a review of the United Nations Office on Drugs and Crime (UNODC) 2019 Action Plan on drugs, Xinhua reported.
Ahead of the meeting, in response to Uruguay's move in legalising the growing, selling, and smoking of the drug in late 2013, UNODC Executive Director Yury Fedotov said he did not believe legalisation to be a solution.
He added that he believes marijuana is a gateway drug, as "no one starts a drug addiction with heroin".
The Action Plan includes the goal of reducing global drug production and consumption by 2019, and to strengthen the social and health support conditions in the fight against narcotics.
Fedotov said the two-day conference involving representatives from UN member states as well as civil society would represent a milestone ahead of a planned UN General Assembly Special Session on Drugs (UNGASS) in 2016, where further solutions to the global drug problem are expected to be found.
