The visualization shows the retail price of 8 drugs analyzed by UNODC (United Nations Office on Drugs and Crime) in 41 countries. For each country retail price and degree of drug purity are visualized. The 5 most expensive drugs and the 5 cheapest drugs among the countries under review are also listed.
