Average Police Time Taken Per Marijuana Arrest: "In those eleven years the NYPD made a total of 439,056 possession-only arrests. Multiplied by two and a half hours of police time per arrest that equals 1,097,640 hours - or approximately one million hours of police officer time to make 440,000 marijuana arrests. That is the equivalent of having 31 police officers working eight hours a day, 365 days a year, for 11 years, making only marijuana possession arrests."
