New York spends $75 million a year to lock up people caught with marijuana, a new study says, even though it's not technically a crime. The report by the Drug Policy Alliance says the NYPD spends that much on 50,000 annual marijuana arrests, in which 86% of those arrested are black or Latino. State law requires people carrying small amounts of marijuana to receive the equivalent of a traffic ticket, but critics say the NYPD arrests and jails them anyway - hurting their job and life prospects.
