Can Cannabis Help Prevent Dementia?

By Pat Anson, PNN Editor

People use cannabis for a variety of reasons. Some use it to relieve pain. Others use it to help them sleep, improve their appetite, or reduce anxiety and stress. Still others use cannabis because it makes them feel good.

A new study suggests there’s another unexpected benefit from consuming cannabis, especially when it’s used recreationally: It may help middle-aged adults ward of dementia.

Researchers at SUNY Upstate Medical University looked at health survey data that assessed the subjective cognitive decline (SCD) of over 4,700 U.S. adults between the ages of 45 and 64. Memory loss and confusion are symptoms of SCD, which is considered an early sign of dementia.

To their surprise, researchers found that participants who only used cannabis recreationally had significantly lower risk of SCD – as much as 96% less risk compared to non-users. Those who used cannabis for medical reasons or combined it with recreational use also had lower odds of SCD, but the difference was not statistically significant.

“We found that non-medical cannabis use was significantly associated with reduced odds of SCD in comparison to non-users. Several factors might explain this observation. Non-medical use of cannabis often contains THC, which has a psychoactive component that creates the ‘high’ sensation. Whereas CBD is non-psychoactive and often used for anxiety and chronic pain management,” the SUNY research team recently reported in the journal Current Alzheimer Research.

One likely reason for the disparity in SCD between recreational and medical users is that those who consume cannabis for health reasons may have comorbid medical conditions – such as diabetes, hypertension, cardiovascular disease and musculoskeletal disorders -- that raise their risk of dementia.

Another consideration is sleep. One of the primary reasons people use cannabis is to help them fall asleep faster and stay asleep longer. Recreational use of cannabis has the added benefit of improving sleep quality. A recent study found that insomnia is associated with a 51% higher risk of dementia risk.

The frequency of cannabis use and whether it was smoked, vaped or ingested had no significant connection to SCD risk.

Although the study found no direct cause-and-effect relationship between cannabis, SCD and dementia, researchers think it’s worth exploring further. More than six million Americans have Alzheimer’s disease or some form of dementia, a number that’s expected to double by 2050. 

“Despite the advancement of medicine and technology, dementia remains incurable and non-preventable. While some medications can slow symptom progression, they are only effective if started during early stages and cannot reverse its course,” SUNY researchers concluded. “Given the widespread use of cannabis in the U.S., it is imperative to pursue further research to understand the mechanism underlying the reduced odds of SCD among non-medical cannabis users.”

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.

Ending the War on Drugs Probably Won’t Help Pain Patients

By Roger Chriss, PNN Columnist

America’s war on drugs has been running for half a century and calls to bring it to an end are increasing. Lawmakers and public health experts are questioning federal and state policies that criminalize drug use, while the public generally supports less punitive measures to address drug abuse and addiction.

"The war on drugs must end,” said a recent editorial in The Lancet. “Decriminalisation of personal drug use, coupled with increased resources for treatment and harm reduction, alongside wider initiatives to reduce poverty, and improve access to health care, could transform the lives of those affected."

But ending the war on drugs probably won’t help people with chronic painful conditions. That’s because decriminalization of recreational drugs is not necessarily associated with full legalization – as is the case with marijuana -- while legalization of recreational drugs is separate from medical care with pharmaceutical prescriptions.

The debate about how to end the drug war is largely ideological at this point. In the new issue of The American Journal of Ethics, Carl Hart, PhD, author of the book “Drug Use for Grown Ups,” writes with colleagues that laws criminalizing drug use are “rooted in explicit racism.”

"We call for the immediate decriminalization of all so-called recreational drugs and, ultimately, for their timely and appropriate legal regulation," they wrote.

But bioethicist Travis Rieder, PhD, author of the book “In Pain” about his experience with opioid-based pain management, wrote in the same journal that “ending the war on drugs does not require legalization, and the good of racial justice and harm reduction can be achieved without legalization.”

Yet another view comes from Stanford psychiatrist and PROP board member Anna Lembke, MD, who wrote in the Journal of Studies on Alcohol and Drugs that creating a “safe supply” of drugs by legalizing the non-medical use of prescription medication would be a mistake.

“The expanded use of controlled prescription drugs should not occur in the absence of reliable evidence to support it, lest we find ourselves contending with a worse drug crisis than the one we’re already in. No supply of potent, addictive, lethal drugs is ‘safe’ without guarding against misuse, diversion, addiction, and death,” said Lembke.

The Lancet points to Portugal as an example that other countries should follow. But contrary to common belief, Portugal has not legalized drugs. In Portugal, drug possession of no more than a ten-day supply is an administrative offense handled by so-called dissuasion commissions.

Portugal has not even legalized recreational cannabis. Medical cannabis is legal in Portugal, but only when prescribed by a physician and dispensed by a pharmacy if conventional medical treatments have failed. Personal cultivation of cannabis remains against the law.

Further, neither decriminalization nor legalization necessarily improves racial and social justice. For instance, the University of Washington’s Alcohol & Drug Abuse Institute reports that the legalization of cannabis in Washington state in 2012 has had no impact on reducing racial bias in policing and other disparities in the criminal justice system.

Broad drug decriminalization or legalization would likely have little impact on pain management. Healthcare professionals routinely prescribe medications that are illegal outside of clinical medicine, after weighing the risks and benefits for each patient. Patients are often monitored via pain contracts and drug testing, with some agreements even disallowing cannabis and restricting alcohol use for patients taking medications like opioids or benzodiazepines.

Physicians and pharmacies are under increasing scrutiny from law enforcement, insurers and regulators in the hope of curbing drug abuse. If decriminalization or legalization of drugs leads to more abuse, addiction and overdose, then the scrutiny could increase. So in an unexpected way, an end to the war on drugs could have negative impacts on pharmacological pain management.
 
Supporting an end to the war on drugs is a right and just action. But it would be a mistake to assume that an end to that war will necessarily bring a positive change to pain management. For that, it would be better to support physician autonomy and greatly expanded clinical research into pain management.

Is Recreational Drug Use a Human Right?

By Roger Chriss, PNN Columnist

The book “Drug Use for Grown-Ups” by Carl Hart, PhD, is garnering a lot of attention. Hart argues that recreational drug use is a fundamental human right, while also describing the harms of drug laws and policy on people of color. His book is a mixture of anecdote and analysis that raises a lot of important issues about drugs and society.

Hart is unapologetic about his own drug use and that of others, saying that "Adults should be permitted the legal right to sell, purchase, and use recreational drugs of their choice." He sees drug use as “beneficial for human health and functioning” and causing ‘little or no harm” in most instances.

Specifically, Hart states that drug use is an "act that the government is obliged to safeguard” because it is a part of the “pursuit of happiness” in the Declaration of Independence. He claims that Thomas Jefferson, one of the authors of the Declaration, was “a long-term avid drug user.”

Hart, who is a psychology professor at Columbia University, raises numerous questions in a blunt and sometimes brusque fashion, asking “Why is it that guns can be legally purchased but heroin cannot?”

He challenges his readers with remarks like: “Few would balk at using Viagra or Cialis to enhance sexual performance, but many more find it objectionable to use drugs such as amphetamines to improve the sexual experience.”

Hart doesn't mythologize or romanticize drugs or their users, and questions why advocates of the psychedelic movement call themselves “psychonauts.”

“The term psychonaut in itself is another attempt to dissociate middle-class psychedelic users from users of drugs such as crack and heroin, who are disapprovingly called ‘crackheads’ or ‘dope fiends’.”

Hart defends this position by pointing out that nearly 80 percent of illicit drug users don’t have problems such as addiction. He explains that his own heroin use is rational: “Like vacation, sex, and the arts, heroin is one of the tools that I use to maintain my work-life balance.”

As for overdose deaths, Hart contends that contaminated drugs are the issue. “A regulated market, with uniform quality standards, would virtually put an end to contaminated drug consumption and greatly reduce fatal, accidental overdoses,” he writes.

Further, Hart states that drug addiction is not a brain disease, writing that there is no evidence indicating that “responsible recreational drug use” causes brain abnormalities. He says obsessing over addiction has caused harm by stigmatizing drug users as unworthy of social support or rehabilitative care. Hart sees the opioid crisis as overblown and rooted in racism.

“All the evidence from research clearly shows that most heroin users are people who use the drug without problems, such as addiction; they are conscientious and upstanding citizens,” he writes. “The new ‘get tough on opioids’ policies have been fueled by the mistaken perception that most illegal opioid dealers are black or Latino.”

Legalization, Hart claims, is the key to changing all this. Prohibition of alcohol gave birth to criminal gangs and a thriving underground market in booze, some of it so contaminated with impurities it made people sick or even killed them. “This problem went away when Prohibition was repealed,” he points out.

But not all of this holds up so well. Hart argues that a legalized market with regulated substances would keep people safe, but he himself chooses to use an illicit substance called “hex” of unknown provenance and effect while at a drug festival.

“I now include hex among the drugs I might want to take immediately before attending some awful required social event, such as an academic reception or an annual departmental holiday party,” he wrote.

Hart’s book is also notable for what it lacks. He doesn’t look at public health data or long-term studies on drug risks and user outcomes in the U.S. or other countries, and ignores animal research on drug risks and harms.

Hart also omits recent discouraging research on drug legalization and social justice. According to the University of Washington’s Alcohol & Drug Abuse Institute, legalization of cannabis has had no impact on reducing racial bias in policing and other disparities in the criminal justice system.   

He also doesn’t discuss the under-treatment of pain in people of color due to myths about higher pain tolerance, lack of nerve endings, or greater abuse and addiction risk.

Hart clearly shows the harms of current drug policy, but arguably overstates the potential benefits of legalization. And his blunt style sometimes diminishes his own credibility.  Overall, the book “Drug Use for Grown-Ups” adds to the discussion of drug policy in the U.S. by asking some challenging questions, but doesn’t resolve many important issues.

Marijuana Legalized in Several More States

By Ellen Lenox Smith, Columnist

As we ponder the results of the presidential election, let’s not forget to celebrate the success throughout the country in increasing the number of states allowing access to medical and recreational marijuana.

Congratulations to voters in Florida, North Dakota and Arkansas for approving medical marijuana and providing a choice for patients to turn to. Also, Montana succeeded in expanding its medical marijuana program to include post-traumatic stress as a qualifying medical condition, along with raising the limit on the number of patients a doctor can certify from 3 to 25.

We are so happy for patients in these states! It will take time for them to get their programs up and running. Patience will be needed, but at least they are now on the right road. It will involve years of tweaking the program as patients learn to navigate the system.

Voters in California, Nevada, Massachusetts and Maine also approved the legalization of marijuana for recreational use. A recreational ballot proposal in Arizona was defeated.

It is very important that we keep and improve the integrity of medical marijuana programs as states expand into recreational use. This will become a big money maker for states and I assume the movement will grow fairly quickly as more states realize they can make billions of dollars in tax revenue.

I have always felt that recreational use was not our battle, preferring instead to focus on patients having access to medical marijuana. I appreciate that some want marijuana for use socially, but there are many of us struggling to live life with more dignity, which the use of medical marijuana provides for us. All citizens in the United States deserve the same rights and we are now over halfway there.

Our dream is for all people in this country to have medical marijuana as a choice. All deserve proper education on its use, a variety of strains to accommodate their various needs, patients and caregivers should be allowed to grow their own plants, and marijuana should be available at compassion centers or dispensaries at affordable prices. Also, we look forward to more consistency in qualifying medical conditions, which vary widely from state to state.

If you are in need of advocating in your state to improve your program or to try to get legislation to move forward, feel free to be in touch.
