Legal pot increases crime, grows the black market


If you listen to those who want to legalize marijuana in Arizona, you’ll hear promises of how it will lower crime rates and end the black market. As a law enforcement officer in Colorado, I can tell you that these are empty promises and not what’s happening in Colorado. The problems have been much bigger than the benefits.

Since the legalization of marijuana, the black market has grown. Colorado is now perceived as a safe haven for drug activity since marijuana was legalized in 2013 and drug organizations are flocking here to take advantage. That’s not a road Arizona wants to go down.

As someone who works in a unit that specifically targets drug trafficking organizations, I’ve seen first-hand that legalizing marijuana didn’t end the black market. Instead, Colorado became a place for it to thrive. For example, our unit just finished a year-and-half investigation of a group of people who came from Texas and bought homes all across the Denver and Colorado Springs areas for the sole purpose of growing marijuana. There were hundreds of plants on every property.

After a year-long investigation, search warrants were issued, about 40 arrests were made and 30 marijuana grow locations were processed. Over 6,000 pounds of marijuana were seized.  It was all for distribution on the black market in Colorado or in other states. Approximately 30 people were charged with felony crimes related to this particular case. It was a very time-intensive, exhaustive case. Unfortunately, it’s not unique.

People think that because marijuana is legal and you can grow it in your own home that it’s much harder for law enforcement to detect it. They’re right. It’s much harder. That’s why these drug organizations are coming to Colorado. They come to Colorado to essentially hide in plain sight. They will do the same in Arizona.

These out-of-state organized crime groups come to Colorado to take advantage of the laws and put marijuana on the local black market or ship it to other states. They have put a strain on law enforcement’s time and resources. It has added problems at a magnitude we never saw coming.

Unfortunately, every state has problems with drugs. Before legalization in Colorado, marijuana occupied a small amount of our task force’s time and resources. The rest of our time was devoted to taking down meth labs, heroin operations and other drugs. Today there is such a community outcry because of these home-grown operations by drug cartels and the amount of marijuana being sold on the black market that our unit now spends significantly more time on marijuana than we did before legalization.

The idea that legalizing marijuana will stop drug cartels and the black market simply isn’t true and it isn’t what’s happening in Colorado. We’re arresting more people for marijuana-related issues than we ever did before. There are now more violent crimes associated with marijuana, which was not the case 10 years ago. Violent crimes have increased because drug trafficking organizations are moving into Colorado and using the existing laws as a front.

Arizonans need to really do their research and take a look at the effects legalization of marijuana has had on Colorado communities. Drug cartels and the black market are thriving. Police resources are devoted to the illegal sale of marijuana and the violent crimes associated with it more than ever before.

Marijuana legalization hasn’t been a problem solver, but a problem creator.

  1. I guess I’m confused. The officer cites “hundreds of plants on every property”. Was there anything in their ordinace that limited the number of plants? Prop 205 “allows adults to grow up to six marijuana plants in an enclosed, locked space within their residences and possess the marijuana produced by those plants in the location where it was grown. No more than 12 total marijuana plants can be grown in a single residence”. Is the proposal here different than the one in CO? Thanks.

  2. Corrupt Law Enforcement Officials who prefer to ruin peoples lives over Marijuana possession rather than solve real crimes who fund their departments toys and salaries with monies acquired through Marijuana home raids, seizures and forfeitures, – Your Days In Office Are Numbered. Find new careers before you don’t have one.

    Marijuana consumers deserve and demand equal rights and protections under our laws that are currently afforded to the drinkers of far more dangerous and deadly, yet perfectly legal, widely accepted, endlessly advertised and glorified as an All American pastime, booze.

    Plain and simple!

    Legalize Marijuana Nationwide!

    There is absolutely no doubt now that the majority of Americans want to completely legalize marijuana nationwide. Our numbers grow on a daily basis.

    The prohibitionist view on marijuana is the viewpoint of a minority and rapidly shrinking percentage of Americans. It is based upon decades of lies and propaganda.

    Each and every tired old lie they have propagated has been thoroughly proven false by both science and society.

    Their tired old rhetoric no longer holds any validity. The vast majority of Americans have seen through the sham of marijuana prohibition in this day and age. The number of prohibitionists left shrinks on a daily basis.

    With their credibility shattered, and their not so hidden agendas visible to a much wiser public, what’s left for a marijuana prohibitionist to do?

    Maybe, just come to terms with the fact that Marijuana Legalization Nationwide is an inevitable reality that’s approaching much sooner than prohibitionists think, and there is nothing they can do to stop it!

    Legalize Nationwide!…and Support All Marijuana Legalization Efforts!

  3. Legalize Nationwide

    Too sad. The law spends a fortune chasing users/growers while forgetting to go after violent people.

  4. Sgt. Jim Gerhardt is an idiot and a liar in bed with the prison industrial complex.

    Don’t be stupid, Arizona. Colorado got nearly a billion dollars in its economy in 2015, and that’s a billion that didn’t go to organized crime.

  5. Dubious logic through and through as California gets ready to legalize. No one believes drove cops who are so often as corrupt as they come.

    @legalize nationwide
    Trust men they aren’t “forgetting” to go after the violent criminals, they’re just choosing not to because it’s “hard” because violent criminals are, well, violent… as opposed to busting cannabis consumers, who are generally passive and non-confrontational
