Cannabis Legalization Reduced Rx Drug Use for Several Conditions, Not Just Pain

By Pat Anson, PNN Editor

Cannabis products are often touted for their pain relieving properties and some studies have shown that medical marijuana can even help patients reduce their use of opioids.

But a large new study by researchers at Cornell University found that legalization of recreational marijuana significantly reduced demand for a broad range of prescription drugs used to treat depression, anxiety, seizures and other health conditions.

The study, published in the journal Health Economics, looked at prescription data for Medicaid patients in all 50 states from 2011 to 2019, focusing on 11 states where the recreational use of cannabis was legalized: Arizona, Alaska, California, Colorado, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont and Washington.

Researchers found significant reductions in Medicaid prescribing rates for pain and five other condition-specific drug classes after the first year of legalization:

  • -12.2% Anxiety
  • -11.1% Depression
  • -10.8% Sleep  
  • -10.7% Psychosis
  •  -9.5% Seizures
  •    -8% Pain

Prescribing rates for the six conditions declined even more in the second and third years after recreational cannabis was legalized.

"These results have important implications," wrote lead author Shyam Raman, a doctoral student in the Cornell Jeb E. Brooks School of Public Policy. "The reductions in drug utilization that we find could lead to significant cost savings for state Medicaid programs. The results also indicate a potential harm reduction opportunity, as pharmaceutical drugs often come with dangerous side effects or – as with opioids – potential for misuse.”

Raman and his colleagues did not see a measurable change in the prescribing of drugs used to treat nausea, spasticity or glaucoma. They also note that their study did not look at the health of patients who stopped or reduced their use of prescription drugs, or at the long-term effects of substituting cannabis for pharmaceuticals.

A small study at Harvard Medical School recently found that chronic pain patients reported significant improvements in their pain, sleep, mood, anxiety and quality of life after six months of cannabis therapy.

Recreational cannabis is now legal in 18 states and Washington, DC, while medical marijuana is legal in 37 states and Washington, DC. Cannabis has become so popular — and accessible — that a recent Harris poll found that twice as many Americans are using cannabis or cannabidiol (CBD) to manage their pain than opioids.

While the findings are intriguing, the small number of patients involved in most cannabis studies makes it hard to draw firm conclusions. In 2021, two professional pain societies – the International Association for the Study of Pain (IASP) and the Australian and New Zealand College of Anaesthetists -- released policy statements saying they could not endorse the use of cannabis for pain because there are no large, high-quality clinical trials of cannabis as an analgesic.

More Americans Worried About Rx Drug Misuse

By Pat Anson, Editor

A recent study by the Centers for Disease Control and Prevention found that about one in four overdose deaths in 2016 involved prescription opioids. That’s a lot – but it’s far less than the number of Americans killed by illegal drugs such as heroin, cocaine and illicit fentanyl – which account for nearly two-thirds of all drug related deaths.

But a new survey shows that a growing number of Americans still blame the overdose crisis on prescription drugs.

The nationwide poll by the Associated Press and the NORC Center for Public Affairs at the University of Chicago found that 43 percent of Americans believe the misuse of prescription drugs is a serious problem in their community. That’s up from 33% two years ago. Only 37 percent see heroin as a serious concern locally.

The survey findings show that many Americans have a conflicted attitude about the opioid crisis and drug misuse in general.

For example, while over half (53%) believe prescription drug addiction is a disease that is treatable, a significant number (39%) think substance abuse is caused by mental illness. Forty-three percent think opioid addiction shows a lack of willpower or discipline, and nearly a third (32%) say it’s a character defect or a sign of bad parenting.

The stigma associated with drug addiction is strong. Fewer than 1 in 5 Americans are willing to associate closely with a friend, colleague or neighbor who is addicted to prescription drugs.  

"In the national effort to grapple with the enormous issue of opioid addiction, it is important to know the level of awareness and understanding of Americans who find themselves in the midst of an epidemic that is claiming growing numbers of lives," said Caitlin Oppenheimer, senior vice president of public health at NORC. "This survey provides important, and in some cases troubling, information."

Other survey findings:

  • 13% of Americans had a relative or close friend die from an opioid overdose.
  • 24% have an addicted relative, close friend, or say they themselves are addicted to opioids.
  • Two-thirds say their community is not doing enough to make treatment programs accessible and affordable
  • 64% would like to see more effort to crack down on drug dealers.

"The number of people who recognize how serious the opioid epidemic is in this nation is growing," said Trevor Tompson, vice president for public affairs research at NORC. "There is clearly a continuing challenge to ensure that what is learned about the crisis is grounded in fact."

The survey found that Facebook plays a dominant role in how Americans get their news – particularly about opioids. Of the 74 percent of adults who use Facebook, 41 percent say they have seen messages about opioids or deaths from overdoses. Fewer users of Twitter, Instagram and other social media platforms report seeing such information.

The nationwide survey of 1,054 adults was conducted online and using landlines and cell phones. The margin of sampling error is +/- 4.1 percentage points.

How the DEA Changed the Overdose Numbers

By Pat Anson, Editor

The Drug Enforcement Administration has released its annual report on the threat posed to the U.S. by drug trafficking and the abuse of illicit drugs.

The 2017 National Drug Threat Assessment (NDTA) has both good and bad news about the nation’s worsening overdose crisis. But like other federal agencies, the DEA has a disturbing tendency to massage statistics to make the role of opioid pain medication more significant than it actually is.

“The threat posed by controlled prescription drug (CPD) abuse is prevalent. Every year since 2001, CPDs, specifically opioid analgesics have been linked to the largest number of overdose deaths of any illicit drug class, outpacing those for cocaine and heroin combined,” the report declares.

That sure makes it sound like opioid pain medication is killing more people than ever before, doesn’t it? A closer look at the numbers and methodology used by the DEA suggests otherwise.

"Controlled prescription drugs" is a very broad category that includes not only opioid pain relievers, but anti-anxiety drugs (Valium, Xanax), stimulants (Adderall, Ritalin), and anabolic steroids. And there's plenty of evidence people are dying from those drugs as well.

This is not the first time the DEA has lumped opioid pain relievers with other drugs. In the 2016 NDTA, the DEA combined opioids with anti-anxiety drugs, but not stimulants or steroids.

A year earlier, in the 2015 NDTA, prescription opioids were in a category all to themselves.

The effect of these changing and broadening definitions is significant. Every year the overdose crisis appears to be getting worse and worse. It certainly is for deaths linked to illicit drugs like heroin, cocaine and fentanyl, but not necessarily for prescription drugs and definitely not for opioid pain medication.

One has to wonder why these definitions keep changing and distorting the true nature of the overdose crisis. Don’t take my word for it. Look at how the overdose numbers for "Selected Illicit Drugs" in 2013 have grown over the years.

In the 2015 NDTA, the DEA reported that an “opioid analgesic” was involved in the deaths of 16,235 Americans in 2013.

In the 2016 NDTA, the DEA reported that “prescription drugs” were involved in the deaths of 22,767 Americans in 2013.

And in the 2017 NTDA, the DEA reported that “medications” were involved in the deaths of 24,536 Americans in 2013. The "medications" category includes not only controlled prescription drugs, but over-the-counter drugs as well.

Simply by changing the way they counted overdoses, the DEA and other federal agencies raised the death toll for 2013 by over 8,300 people.  We’re only using 2013 as an example.  From one report to the next, overdoses grew for every other year as well.

This isn’t the first time the federal government has played around with the overdose numbers. As PNN reported, last December the CDC and the White House Office of National Drug Control Policy released three different estimates of how many Americans died in 2015 from overdoses linked to prescription opioids.  

Within one week, the overdose numbers evolved from 17,536 deaths, down to 12,700, and then back up to 15,281 deaths. To use a football metaphor, that is known as moving the goalposts.

Pain Medication Abuse Declining

A closer reading of the 2017 NDTA shows that heroin, illicit fentanyl and other illegal drugs are now driving the overdose crisis, not opioid pain medication. Less than one percent of legally prescribed opioids are being diverted to the black market. 

A recent survey of law enforcement agencies, known as the National Drug Threat Survey, found that less than 10 percent of respondents nationwide believed controlled prescription drugs were the greatest drug threat in their jurisdiction -- down considerably from 2014 when over 21.5 percent reported the same

The abuse of prescription opioids is also declining. Fewer Americans are testing positive for hydrocodone, oxycodone and other painkillers in workplace drug tests. And the number of people seeking treatment for abusing pain medication has fallen significantly. From 2011 to 2014, admissions to publicly-funded treatment facilities for prescription opioid abuse fell by nearly a third. 

“This decline can in part be attributed to CPD (controlled prescription drugs) abusers switching to heroin or other illicit opioids. Some CPD abusers, when unable to obtain or afford CPDs, begin using heroin as a cheaper alternative offering similar opioid-like effects,” said the DEA.

“Expansion of the counterfeit pill market, to include pills containing fentanyl, threatens to circumvent efforts by law enforcement and public health officials to reduce the abuse of opioid medications; the arrival of large amounts of counterfeit prescription drugs containing fentanyl on the market replaces opioid medications taken off of the street.”

Curiously, the DEA report doesn’t even list kratom as a drug threat – even though the agency considers the herbal supplement a “drug of concern” and tried to ban it last year. 

“I think that all of us in the kratom community have a hard time reconciling the lack of a threat listing for kratom and yet still being considered a drug of concern,” said Dave Herman, chairman of the American Kratom Association, a pro-kratom consumer group.  “The science tells us that kratom has a low potential for either abuse or addiction and we hope to see that reflected in all DEA materials.”

Whether its kratom or pain medication, the DEA and other federal agencies have a responsibility to be consistent and to get their facts right.  Inflating the overdose numbers and blaming opioid medication may make for good headlines, but it diverts funding, resources and policymakers away from other drug problems that truly need more attention. We'll never get a handle on the overdose crisis if we keep moving the goalposts.

A recent editorial in the Journal of Pain Research took the CDC to task for doing just that.

"Transparency, freedom from bias, and accountability are, in principle, hallmarks of taxpayer-funded institutions. Unfortunately, it seems that at least one institution, the Centers for Disease Control and Prevention, continues to struggle with all three," wrote researchers Michael Schatman, PhD, and Stephen Ziegler, PhD.

"What began with a prescribing guideline created in secrecy has now evolved to the use of statistical data and public statements that fail to capture not only the complexity of the problem but also the distinction between licit and illicit opioids and their relationship to the alarming increase in unintentional overdose. This is unfortunately consistent with Mark Twain’s assertion that 'there are lies, there are damn lies, and then there are statistics.'"
