A study released [in April, 2008] reported that between 1998 and 2007, the police arrested 374,900 people whose most serious crime was the lowest-level misdemeanor marijuana offense.
...Nearly everyone involved in this wave of marijuana arrests is male: 90 percent were men, although national studies show that men and women use pot in roughly equal rates. And 83 percent of those charged in these cases were black or Latino, according to the study. Blacks accounted for 52 percent of the arrests, twice their share of the city's population. Whites, who are about 35 percent of the population, were only 15 percent of those charged -- even though federal surveys show that whites are more likely than blacks or Latinos to use pot.
Among the pretty large population of white people who have used pot and not been arrested for it is Mayor Michael R. Bloomberg. Asked during the 2001 campaign by New York magazine if he had ever smoked it, Mr. Bloomberg replied: "You bet I did. And I enjoyed it." After he was elected and his remarks were used in advertisements by marijuana legalization advocates, Mr.Bloomberg said his administration would vigorously enforce the laws.
