Study: Cannabis Shows No Long-Term Impact on Brain Function
In recent years, the debate surrounding cannabis effect on brain function has intensified, especially as more states and countries move toward legalizing the drug for both medical and recreational use. Historically, marijuana has been associated with cognitive impairments, particularly in areas such as memory, attention, and executive function. However, a new study published by the American Medical Association (AMA) challenges this long-standing view, suggesting that moderate cannabis use does not significantly impair certain cognitive processes such as working memory, reward processing, and inhibitory control. This groundbreaking research shifts the conversation about cannabis, particularly in its medical applications, and prompts a re-evaluation of prior assumptions.
Background: Changing Perceptions of Cannabis
For decades, cannabis was largely viewed as a recreational substance that carried risks of addiction, cognitive decline, and other negative health outcomes, particularly in adolescents and heavy users. Early studies indicated that cannabis use, especially when initiated during adolescence, could impair brain development and lead to long-term cognitive deficits. This perspective influenced policy and public opinion, leading to its classification as a Schedule I substance in the United States, alongside drugs like heroin and LSD.
However, as cannabis legalization has gained momentum, the need for a more nuanced understanding of its effects has become increasingly important. Medical cannabis, in particular, is used to manage conditions such as chronic pain, anxiety, and depression. These evolving applications prompted researchers to take a closer look at how cannabis affects brain function, especially in moderate, controlled doses for medical use.
The AMA Study: Key Findings
The AMA-funded study, published in JAMA Network Open, investigated the long-term effects of marijuana use on cognitive functions. The research focused on adults who were using medical cannabis to manage symptoms like chronic pain, anxiety, and depression. Researchers utilized functional magnetic resonance imaging (fMRI) to assess brain activity related to working memory, reward processing, and inhibitory control tasks at baseline and after one year of moderate cannabis use.
The results were surprising. Contrary to previous assumptions, the study found no significant differences in brain activation between the two time points, even after a year of consistent marijuana use. Specifically, the researchers reported that “working memory, reward, and inhibitory control tasks did not differ statistically from baseline to one year and were not associated with changes in cannabis use frequency.” This suggests that moderate cannabis use for medical purposes does not impair these key areas of cognitive function.
Furthermore, the study noted that prior research on marijuana’s cognitive impacts often focused on adolescents or heavy, recreational users, which could explain the previously observed deficits. The current study’s focus on adults using cannabis for medical purposes, and typically in moderate amounts, paints a different picture, indicating that the cognitive risks associated with cannabis may not apply equally to all users.
Implications for Medical Marijuana Patients
The AMA study offers promising news for medical marijuana patients. Many individuals who use cannabis to manage chronic health conditions often worry about the potential cognitive side effects of long-term use. This research provides some reassurance that moderate use, particularly in adults, may not carry the same risks as previously thought.
For patients dealing with chronic pain, anxiety, or depression, medical marijuana has often been viewed as a trade-off: potential relief from debilitating symptoms in exchange for possible cognitive decline. The findings of this study suggest that for those using cannabis in controlled, moderate amounts, the cognitive risks may be minimal. This is especially important for patients who rely on cannabis to manage their symptoms without the use of more addictive medications, such as opioids.
The Importance of Context: Adolescents vs. Adults
One key takeaway from the AMA study is the distinction between the effects of cannabis on adolescents and adults. Prior studies have shown that cannabis use, particularly when started in adolescence, can lead to long-term cognitive impairments. The adolescent brain is still in a critical stage of development, and cannabis use during this period has been linked to changes in brain structure and function.
However, the AMA study focused on adult users, who have fully developed brains, and the results suggest that moderate cannabis use in this population does not have the same deleterious effects. This highlights the importance of considering age and developmental stage when discussing the risks associated with marijuana use. While cannabis may still pose risks for younger users, adults who use it for medical purposes may experience fewer cognitive side effects than previously believed.
Long-Term Cognitive Effects: What We Still Don’t Know
While the AMA study provides valuable insights, it also underscores the need for further research. The study focused on light to moderate cannabis use for medical purposes, and it’s unclear whether the findings would hold true for heavier use or for recreational users. Additionally, the study’s participants were adults with chronic health conditions, a group that may respond differently to cannabis than the general population.
Further studies are needed to explore the effects of higher doses of cannabis, different consumption methods (such as smoking vs. edibles), and the long-term cognitive effects across a broader range of populations. As more states legalize cannabis, the number of users is likely to increase, making it even more important to understand the full scope of marijuana’s impact on brain function.
Potential Policy Implications
The AMA’s findings could have significant implications for cannabis policy. As more evidence emerges suggesting that moderate cannabis use does not impair cognitive function, there may be increased pressure to reclassify cannabis under federal law. Currently, its Schedule I classification denotes that it has “no accepted medical use and a high potential for abuse,” a categorization that is increasingly at odds with scientific research and public opinion.
If further research continues to support the AMA’s findings, policymakers may be more inclined to reconsider cannabis’s legal status. Additionally, this research could influence the guidelines and recommendations for medical marijuana use, helping to establish safe, evidence-based dosing protocols for patients.
Conclusion
The AMA study offers new insights into the effects of marijuana on brain function, challenging long-held assumptions about its cognitive risks. For adults using cannabis moderately to manage medical symptoms, the findings are reassuring, suggesting that key cognitive processes like working memory and reward processing are not significantly impacted by long-term use. However, more research is needed to fully understand the broader implications of these findings, particularly in younger populations and heavier users. As the legal landscape around cannabis continues to evolve, studies like this one will be critical in shaping our understanding of marijuana’s role in both medical and recreational contexts.

Did James Bond make the martini famous? Or did the martini help make Bond cool?
The classic line of “shaken or stirred” has been used by men for decades. Bond instructs the bartender in the phrase “shaken and not stirred” in Diamonds Are Forever and Dr No and it has been in our lexicon ever since. But did Bond make the martini famous – or did the martini help Bond. And what is the perfect James Bond Martini?
The history of the martini is murky, “Professor” Jerry Thomas, a famous and influential 19th century bartender, invented the drink at the Occidental Hotel in San Francisco, sometime in the late 1850s or early 1860s. As the story goes, a miner, about to set out on a journey to Martinez, California, put a gold nugget on the bar and asked Thomas to mix him up something special. Thomas produced a drink containing Old Tom (sweetened) gin, vermouth, bitters and Maraschino, and dubbed it the “Martinez” in honor of the customer’s destination.

The big question is gin or vodka? Purist insist it be gin for the classic martini, but numbers say vodka is preferred. Vodka sales are about $7.5 billion annually while gin is around $5 billion. If you order a classic martini, you will probably be served gin unless you say vodka. Bond seems fairly fluid in his choice, he orders 19 vodka martinis and 16 gin martinis throughout Fleming’s novels and short stories.
Like Bond’s creator Ian Fleming, James Bond prefers his cocktails shaken and not stirred. A traditional martini is stirred rather than shaken, but Fleming’s biographer Andrew Lycett shared the author preferred martinis shaken since he believe it preserved the flavor.
“The perfect Martini, to me, takes advantage of the “blank canvas” nature of this timeless cocktail. “Many cocktails restrict you to specific garnishes, and even fewer allow the liberty to swap the base spirit.
With the Martini, a vodka base that’s heavy on the olives and light on the vermouth is just as “right” as one made with gin and a twist of lemon, even though they couldn’t be more different once you take your first sip. Accompanied by a bowl of olives, bleu cheese or salty potato chips to snack on, and I’ll savor this iconic cocktail in bliss.
I personally love the body, complexity and herbaceous kick of vermouth, often making it a co-star in my version”

His mentioning marijuana at the State of The Union was historic, but boy did he get some feedback when he tweeted.
The State of the Union address for many years was referred to as “the President’s Annual Message to Congress“. It is believed George Washington started the tradition and the term “State of the Union” first emerged in 1934 when used by Franklin D. Roosevelt (FDR). President Biden mention of marijuana was historic and also showed how the plants reputation has come a long way from the war on drugs. And when he tweeted about it, things got spicy. Biden’s weed tweet got numbers and feedback – and the administration might be wise to pay attention.

The tweet on cannabis reached 14 million and had 12,000 comments and 104,000 likes. The President mentioned his marijuana pardons which drew a significant amount of feedback. According to BDSA, a leading analytics firm covering cannabis, the industry generated $29.5 billion in revue in 2023. When talking about a need to grow the economy and taxes, here is a fresh industry the public wants, but antiquated laws are punishing small businesses.
When you subtract comments not relating to weed, they fall in three categories. The first is the remaining resentment toward Vice President Harris for her historic stance on marijuana. The industry was at first excited when Biden was elected as he indicated he would move opening up legalization for cannabis. His slow pace along with VP Harris’s previous role has frustrated the industry and it shows by the sharp remarks.
Another large batch of comments were just about making a move already! Science, the American Medical Association, and the federal departments of the Healthy and Human Services (HHS) and Food and Drug Administration (FDA) have all said there are benefits. People are clamoring for him to act and act quickly. But, it seems to the public eye, the administration has been very slow in fullfilling this promise from over 2020.

The third big conversation is his perception his pardons did more than they actually did for prisoners. Again, there is hard feelings about it and the online community want him to understand what he did and did not do.
While the industry is expanding, it is still in growth mode and needs basic help in continuing to grow. Rescheduling would allow state cannabis operators to take federal tax deductions they’re currently barred from under an Internal Revenue Service (IRS) code known as 280E. This would give immediate benefits to the cannabis industry which is 50+% small businesses.
Opioids and fentanyl driving a crisis in recent years, with the COVID-19 pandemic exacerbating the public’s abuse of the drug. The crisis has also become a major U.S. foreign policy issue. Massive lawsuits have been filling the courts due to the addictive and damaging nature of some opioids and patients have been left in shambles. Now, data shows medical marijuana reduces opioid use.

A new study from New York State and CUNY researchers suggests receiving medical cannabis for thirty days or more may help patients on long-term opioid treatment to lower their dose over time.
Another study conducted by the American Medical Association showed positive data. The study, published in JAMA Oncology, analyzed the results of thousands of patients with different types of cancer. ound an association between receiving medical cannabis for chronic pain for a longer duration and a reduction in prescription opioid dosages among patients on long-term opioid therapy. Patients who were on higher baseline dosages of prescription opioids when they started receiving medical cannabis experienced larger reductions in opioid dosages.
Researchers explained that the study was conducted in order to explore the links that exist between marijuana legalization and opioid use. They concluded that medical marijuana curbed opioid use and provided an alternate route for treatment.

“Findings of this cross-sectional study suggest that medical marijuana legalization implemented from 2012 to 2017 was associated with a lower rate of opioid dispensing and pain-related hospital events among some adults receiving treatment for newly diagnosed cancer,” they wrote.
“The nature of these associations and their implications for patient safety and quality of life need to be further investigated,” researchers added.
Medical marijuana has less of an impact on the body and mind. Cannabis can be an effective treatment for pain, greatly reduces the chance of dependence, and eliminates the risk of fatal overdose compared to opioid-based medications. Medical cannabis patients report that cannabis is just as effective, if not more, than opioid-based medications for pain.
With medical marijuana available in 40 states, this is indeed good news for most patients.
