The state of New Jersey is arresting more people for cannabis than ever before, a recent study by the state’s American Civil Liberties Union found.

In 2013, the state’s law enforcement made 26 percent more cannabis possession arrests compared to arrests made in 2000. New Jersey police made nearly 280,000 total possession arrests during that time. Possession arrests made up 88 percent of total cannabis arrests. Therefore, the ACLU concluded than nine out of ten total arrests were made against cannabis users rather than dealers.

The report also found that black New Jerseyans were three times more likely to be arrested for cannabis possession than their white counterparts. The rate of black New Jerseyans being arrested was as high as 31.8 times in one municipality.

The study concluded New Jersey has spent more than $1 billion enforcing cannabis laws, at a rate of about $143 million per year.
