When mainstream news outlets—particularly those that lean conservative—publish stories about marijuana, they still tend to perpetuate stereotypes about cannabis with depictions of lazy stoner culture and criminal activity, a new study found.
“This study starkly demonstrated the heavily politicalized nature of marijuana legalization,” the paper states. “Conservative news outlets depicted stereotypes more frequently than liberal or neutral outlets, and this pattern held true in both visuals and their accompanying headlines.”
Researchers also found that “the legalization of marijuana did little to decrease these stereotypes.”
The study, which was published in the journal Visual Communication last month, focuses on how visual framing in mass media impacts the social reality of controversial issues such as marijuana legalization, which is still widely stigmatized in parts of the United States. Many people continue to believe marijuana users are dangerous criminals, lazy stoners or rebellious outcasts.
For their analysis, the study’s authors searched select American online news sites for cannabis-related articles published from June 1, 2013 to July 1, 2014 (that is, the six months before and the six months after legal marijuana sales began in Colorado). They ultimately gathered 458 visuals from 10 different media outlets: four sites they categorized as conservative (Dallas Morning News, New York Daily News, New York Post, Houston Chronicle), four liberal sites (Los Angeles Times, New York Times, Washington Post, Chicago Tribune), and two they deemed neutral sites (USA Today and Wall Street Journal). A majority of the images (268) were taken from stories published after Colorado legalized adult-use.
Researchers then took the visuals and divided them into broad categories based on cultural, racial and criminal stereotypes. They also assessed how headlines were used to frame the images.
According to their findings, there were more images that did not contain stereotypes than ones that did. However, 21 percent of photos featured pot culture stereotypes. For example, the New York Post published a photo featuring an Asian man presumably in his 20s smoking from a bong, his face obscured by smoke. Other images included close-ups of rolled joints and festivals featuring young people hanging out amidst clouds of smoke.
Additionally, 15 percent of images associated criminal behavior with marijuana, and often featured a person of color getting arrested or in court. “Overall,” the study’s authors write, “more racial minorities are depicted as criminals (21.5%) than are non-racial minorities (13.4%). Further, significantly more racial minorities are associated with headlines with a topic about crime (42.5%) than are non-racial minorities (23.1%)”
As for political ideology, conservative news sites depicted racial minorities, criminal stereotypes and pot culture stereotypes more frequently than liberal or neutral publications.
Importantly, the study also assessed how often news organizations used images that normalize marijuana: These include photos of the cannabis plant as opposed to a joint, images of bud in a laboratory setting, or pictures of families or couples. “Politically neutral news sites visually depict normification in images significantly more frequently (9.0%) than liberal (8.6%) news outlets,” the study’s authors write. “Conservative news outlets were significantly less likely to depict marijuana use as normal than either of the two other ideologies (1.9%).”
Interestingly, after Colorado approved adult-use, the prevalence of these types of photos did not increase significantly.
“Broadly,” the authors wrote, “this study suggests that ‘ready-made’ images of what marijuana users are supposed to look like are indeed being used and reinforced by the media. As more states begin to acknowledge the false propaganda and exaggerations associated with marijuana’s history in the U.S. through legalization efforts, the media will play a leading role in either reinforcing or debunking these myths through the representations they choose to visually illustrate the issue.”
“The heavy reliance on stereotypes of marijuana users is an ethical issue, as media representations will influence how audiences draw conclusions about marijuana use, judge the character of its users, and continue to either stigmatize users or open up new spaces within commercial media culture for alternate, more mainstreamed marijuana use,” the study concluded.
It’s clear we’ve got a ways to go. Last month, popular online news site Vox published an explainer on the current state of marijuana legalization in the U.S. Sharing that story on Twitter, the news site’s account tweeted: “9 questions about marijuana legalization you were too stoned to ask.”

Medical Marijuana Patients With ADHD Use Fewer Prescription Drugs, Study Finds
When people with attention-deficit hyperactivity disorder (ADHD) consume more medical marijuana they tend to use fewer prescription drugs, including powerful, habit-forming psychostimulants, according to a new study.
Patients who used medical cannabis components—cannabinoids themselves as well as terpenes— also “reported a higher occurrence of stopping all ADHD medications,” the researchers, whose findings were published late last month in the Rambam Maimonides Medical Journal, wrote.
“In this study, we demonstrated that patients treated with [medical cannabis] stopped their ADHD medications, especially in the high MC dose and in the low ADHD symptoms frequency subgroups.”
Specifically, the study found that the cannabinoid CBN, or cannabinol, which is found in the plant in only trace amounts, seemed to trigger the best results—though they conceded that “more studies are needed in order to fully understand” if cannabis and its constituents can be a workable ADHD treatment.
“These results, although not causal, might shed light on the potential beneficial effects of [medical cannabis] on ADHD symptom severity and motivate future prospective studies in order to validate our results,” the researchers concluded, “and perhaps even consider making ADHD an approved indication” for medical cannabis where it is legal.
The team collected data from 53 Israeli medical cannabis patients in an existing database who had previously agreed to participate in surveys and who also had an ADHD diagnosis. Thirty-seven of the 53 patients suffered from some from of mental health condition.
Participants were asked to self-report monthly doses, how they consumed cannabis, the manufacturer or grower and the cultivar name (or strain) between October 2019 and January 2020.
“These findings reveal that the higher-dose consumption of [medical cannabis] components (phyto-cannabinoids and terpenes) is associated with ADHD medication reduction.”
This is a departure from previous research into ADHD and cannabis, the researchers noted. Prior studies had “considered cannabis as a single product in ADHD research, disregarding its inherent complexities and variability between cultivars and combinations of cultivars,” they wrote.
Most patients had previously obtained medical cannabis licenses (the terminology used in Israel) for chronic pain or cancer treatment rather than neurological disorders that co-exist with ADHD.
Forty-seven patients in the study, which was funded by the Evelyn Gruss Lipper Charitable Foundation, reported either smoking or vaporizing their cannabis.
The cannabis consumers were divided into two subgroups: high dose and low dose. Cultivar combinations were complicated: There were 27 different combinations of varieties but, in addition to CBN, the cannabinoids most associated with reduced or eliminated ADHD medication use including THC, THCV and CBD.
Exactly how various combinations of cannabinoids and terpenes “modulate the circuitry involved in both ADHD and comorbid psychiatric conditions” is still unclear, the researchers said. But the study also suggests that finding the proper dose and the proper cultivar—and cultivar combination—may require significant experimentation on the part of the patient.
And patients in Israel enjoy more reliable access to more regulated cultivars than patients anywhere else in the world—suggesting that most American patients, with a basic understanding of THC and CBD and not a lot else, still have a ways to go.
“This indicates a more complex story than simply stratifying treatment based on THC and CBD alone,” the researchers wrote.
Hemp Is For Horses? New Study Examines CBD’s Calming And Painkilling Effects In Animals
Imagine you’re a race horse. Do you get nervous before the starting bell?
Scientists are curious to learn if CBD might help.
The hype around cannabidiol has hit the equestrian world hard since the 2018 Farm Bill federally legalized industrial hemp and its derivatives, including CBD. While federal officials have yet to finalize rules formally allowing the non-intoxicating cannabinoid in animal feed—or in food products for humans for that matter—CBD supplements have become hot products among horse owners looking to ease pain, reduce pain in muscles and joints and calm signs of stress in their animals.
Now researchers want to know if they actually work. A Texas-based team is currently collecting data on how CBD affects equine physiology. In particular, their new study is examining whether the cannabis compound can help reduce stress, inflammation and obsessive compulsive behaviors in horses.
“I had been interested in the CBD movement for a while, and primarily it is because we’re in a highly horse-populated area,” said Kimberly Guay, a professor at Tarleton State University in Stephenville who specializes in how stress affects animals. “A lot of the horse people I knew were already using CBD, illegally you would say, because it wasn’t legal in Texas at the time.”
Guay’s team is experimenting by giving horses various doses of CBD, generally in the form of oils and edible pellets, and then assessing how they respond. Researchers monitor the animals’ heart rates, inflammation and levels of cortisol, a hormone animals produce under stress. They also observe the horses’ behavior, looking for how CBD affects behavioral indications of pain, stiffness or anxiety.
Guay herself said she has no vested interest in the outcome of the study and doesn’t currently give CBD to her own horse, but she’s eager to see whether the data support what she’s heard from other owners. “The anecdotal evidence is incredibly strong,” Guay told Marijuana Moment in an interview. “And if there is a chance to mediate stress, then I’m all for it.”
The team is aiming to publish the results of the study next year, but Guay said some initial findings could be available as soon as this fall.
“I still can’t say one way or the other, but I know there’s no adverse effects, apparently,” she said, explaining that researchers have given some animals “a significant dose, and there was no obvious adverse reactions from it.”
Across the country, the U.S. Equestrian Federation, which sets the rules for most of the country’s competitive horse events, noted last year that “cannabinoids have gained increased attention and have become nearly mainstream.”
But the rulemaking body said that a horse testing positive for CBD violates competition rules because the cannabinoid is “likely to [affect] the performance of a horse due to its reported anxiolytic effects,” referring to the compound’s apparent role in reducing anxiety.
The U.S. Food and Drug Administration is responsible for regulating the country’s animal feed, and so far CBD has been forbidden. Guay said that if the horse study shows positive results, CBD could also be looked at as a supplement for livestock used for food production.
“If there’s some version of the byproduct of the plant in hemp that could be utilized or incorporated into feed or whatever that could help minimize stress for livestock animals, that would be a huge benefit,” she said.
Currently stress in livestock is managed either with behavioral controls, such as limiting the amount of time animals spend in confined spaces, or through the use of sedative drugs. But sedatives, Guay said, can affect an animal’s balance and its ability to regulate body temperature.
Anecdotally, horse owners who experimented with giving CBD to their animals continued using it “because they believed so strongly in the effects CBD was giving them without the need for sedation,” Guay said.
“That intrigued me,” she added. “We can get the empirical evidence, it’s just going to take time and some effort.”
Most horse owners she’s talked to are on board with the study, Guay said, and are eager to hear the results. But stigma around CBD, even when produced from industrial hemp, remains evident in her home state of Texas, which legalized hemp and CBD production in mid-2019. Federal regulators approved the state’s hemp plan last month.
Guay told Marijuana Moment that she’d been interested in studying the effects of CBD on horses prior to Texas legalizing, but the university system was wary. “I had been chasing this project for a year before it was legal in Texas, and the A&M system would not give me clearance,” she said. “I knew the wave was coming.”
Even today, there are still lingering fears. “People holler at [research assistants] on the phone and voice their opinion,” Guay said, “and some people hang up on them because of that stereotype, that stigma that comes with CBD so far.”
Among the broader veterinary community, that stigma is slowly fading. A survey last year found that most veterinarians consider themselves fairly knowledgeable about recommending cannabinoid therapy for dogs, for example. The problem? Respondents said their state veterinary associations didn’t provide specific guidance on the subject, even in states where cannabis was legal. They also felt research was lacking.
More research is coming, even if it’s not quite keeping up with industry hype. In his annual budget proposal released last week, President Donald Trump directed $500,000 to the FDA’s Animal Drugs and Feeds program in order to “strengthen its capacity to evaluate scientific data related to the safe use of cannabis and cannabis derivatives in animal products.”
Asked if she’d tried CBD herself since Texas legalized the products, Guay at Tarleton State said she had. “Of course I’m going to try it,” she replied. “We’re making our animals ingest it, so I wanted to see what their experience is. They can’t talk.”
She hasn’t noticed many effects so far from cannabis oils, she said, other than “some versions taste terrible.” But after recently using a topical cream, she felt the product may actually have helped. “I have tennis elbow, and I rubbed it on my elbow, and I feel like it significantly helps my elbow. It reduced the pain in my elbow,” she said.
Despite a positive result, Guay knows her evidence is only anecdotal. She knows better than to put stock in what could be a placebo affect.
“I’d have to quantify it,” she said. “I always need numbers.”
Lasers Can Tell Hemp And Marijuana Apart With ‘100 Percent Accuracy,’ Scientists Reveal
Hemp can look and smell like marijuana, presenting a series of challenges to law enforcement and farmers alike. But according to new research, lasers can be used to tell the difference between the two cannabis crops in a fast, affordable and highly precise way.
In a study published last month in the journal RSC Advances, a team of researchers at Texas A&M University were able to “determine whether plant material is hemp or [marijuana] with 100% accuracy” by using a hand-held laser device called a Raman spectrometer (RS).
To test whether the tool could effectively distinguish the two plants, fresh samples of hemp and marijuana strains were frozen, which, according to the authors, “does not result in any noticeable changes in plant appearance or texture.”
The researchers observed that lasers could reliably map a “change of intensities” in vibrational bands, which indicated “structural differences between hemp and [marijuana] plants.”
The results found that hemp has more cellulose, compared to marijuana plants.
“Because of the portable nature of our analysis, this spectroscopic approach will be highly advantageous for police and border control officers.”
The Raman spectrometer was also shown to potentially identify different strains by accurately measuring the potency of individual plants, which “can be used for confirmatory, non-invasive and non-destructive detection and identification of cannabis,” the authors wrote.
The researchers noted that their device detects delta-9-tetrahydrocannabinolic acid (THCA) which is itself non-psychoactive but turns into the intoxicating compound THC when it undergoes decarboxylation (usually by being heated). “[W]e can speculate that RS allows to predict the amount of THC in the analyzed sample without necessary oxidation of THCA to THC,” they wrote.
Additional laboratory testing is underway “to determine accuracy and range” of THCA prediction with the device.
Hemp is defined under federal law as having no more than 0.3 percent total THC, with a negligence threshold of 0.5 percent. And while there’s strong bipartisan interest in ensuring that hemp farmers have the resources they need following the crop’s federal legalization, proving that the plant isn’t marijuana currently requires costly and lengthy laboratory analysis.
“These results demonstrate that RS can be a great tool for hemp cultivation and breeding allowing for accurate detection of THCA levels in intact growing plants.”
With the right tools, officials could quickly determine whether a plant in question is hemp or marijuana, which remains prohibited federally and in several states.
In December, a Texas man was arrested when his vehicle was found hauling more than a ton of cannabis through Amarillo. The plants were seized, and the driver spent almost a month in jail before lab results showed he was transporting hemp.
Other similar discrepancies and mistakes are likely to keep occurring in states and municipalities across the country as new hemp laws come online.
Marijuana prosecutions in Texas were cut in half after hemp laws changed, for example, an unintentional side effect of expanding access to the non-intoxicating cannabis crop. Because police officers in many cases can’t determine whether a cannabis sample is legal hemp or illegal marijuana, prosecutors in the state and others across the country have stopped pursuing many cases until testing methods are more readily available.
The promising new laser technology could mean fewer headaches on the part of state and federal regulators—and a lower risk of getting tied up with law enforcement for law-abiding hemp traders.
“These findings suggest that a hand-held Raman spectrometer can be an ideal tool for police officers and hemp breeders to enable highly accurate diagnostics of THCA content in plants,” the researchers concluded.
