Drug abuse kills about 200,000 people worldwide each year, according to a new United Nations (UN) report. Global treatment for drug abuse would cost $250 billion per year if everyone who needed help received proper care, according to the UN. Fewer than one in five people who need treatment actually receive it, according to the Associated Press. Crimes committed by people who need money to finance their drug habit, as well as loss of productivity, add tremendous costs for many countries, the report notes.
