More than 1.5 million people were arrested for drug offenses in the US last year, and more than 693,000 of those for marijuana offenses. The figures come from the FBI's 2013 Uniform Crime Report, which was released today.

That's about one pot bust and slightly more than one other drug arrest every minute, 365 days a year. The vast majority of them are for simple possession. Over 87% of all marijuana arrests and 82% of all drug arrests were for possession only.

Marijuana arrests have declined from peaks early in this century. In 2008, there were a record 872,000 marijuana arrests, so pot busts have declined by slightly more than 20% since then. But arrests for other drug offenses continue apace, actually increasingly slightly last year. Still, because of the decline in marijuana arrests, the overall number of drug arrests dropped by about 50,000.

In 2008, marijuana arrests accounted for a majority (52%) of all drug arrests. Now, it is down to 40.6%.

Some of the decline in marijuana arrests can be attributed to the passage of decriminalization and legalization laws, particularly in the West, where pot arrests accounted for only 18% of all drug arrests. California decriminalized pot possession in 2011, and Colorado and Washington legalized it in the 2012 elections.

In other parts of the country, marijuana arrests continued to roll along, even in the Northeast, where they accounted for 46% of all drug arrests. In the South, the figure was 49.8%, and in the Midwest, pot accounted for 51.7% of all drug arrests.

When it comes to race, blacks continue to be disproportionately represented among drug arrestees. African-Americans accounted for 30.7% of all drug arrests, but they only make up about 13% of the population. That means blacks are being arrested for drugs at 2 ½ times the rate their percentage of the population would predict.

Drug arrests were the single largest category of arrests made in the US and accounted for about 13% of all arrests. The 1.5 million drug arrests well exceeded second place larceny-theft (1.232 million) and third place driving under the influence (1.167 million). More than three times as many people were arrested for drug offenses than for all violent crimes combined (480,000).

The continued law enforcement emphasis on drug enforcement drew criticism from Law Enforcement Against Prohibition (LEAP).

"Police made more drug arrests than for any other single category of crime. Meanwhile, only 64% of murders and 48% of violent crimes generally are being solved," said LEAP executive director Major Neill Franklin (Ret.), citing the FBI statistics. "We clearly have our priorities in the wrong place."

The Marijuana Policy Project (MPP), fresh from last week's successful "marijuana midterms," pronounced itself pleased with the decline in pot busts, but called for them to end, not just diminish.

"We're pleased to see the drop, but arresting even one adult for using a substance that is objectively less harmful than alcohol is inexcusable," said MPP communications director Mason Tvert. "Every year we see millions of violent crimes attributed to alcohol, and the evidence is clear that marijuana is not a significant contributing factor in such incidents. Yet our laws continue to steer adults toward drinking by threatening to punish them if they make the safer choice. These arrest numbers demonstrate that the threat is very real," he noted.

Tvert also echoed LEAP in criticizing law enforcement priorities.

"Law enforcement officials should be spending their time and resources addressing serious crimes, not arresting and prosecuting adults for using marijuana," he said. "Every year, these statistics show hundreds of thousands of marijuana-related arrests are taking place and countless violent crimes are going unsolved. We have to wonder how many of those crimes could be solved -- or prevented -- if police weren't wasting their time enforcing failed marijuana prohibition laws."

The laws must change, he said.

"A majority of Americans think marijuana should be legal for adults and treated similarly to alcohol. Voters in four states and the District of Columbia have now passed laws that reflect that, and we expect several more will do over the next few years. It's time for our laws to catch up with public opinion."
