University of Toronto Study Finds Teen Marijuana Use Tied To Dramatic Increased Risk Of Psychosis
From the Daily Caller News Foundation
A study published Wednesday found that teens who use cannabis are 11 times more likely to be diagnosed with a psychotic disorder, according to NBC News.
The study was led by researchers from the University of Toronto and examined teenage patients who used cannabis within the last year and those who did not, according to NBC News. When the study was further limited to teens who were sent to the emergency room or hospitalized, it showed a 27-fold increase in the likelihood of being diagnosed with psychotic illness.
“I think that there’s enough evidence out there for us to give recommendations that teens probably shouldn’t be using cannabis,” Andre McDonald, a postdoctoral research fellow at McMaster University and lead author of the study, said, according to NBC News. “If we can somehow ask teens to delay their use until their brain has developed a little further, I think that would be good for public health.”
While the research does not prove that cannabis use by teens causes psychosis, Dr. Leslie Hulvershorn, a child psychiatrist who was not involved with the study, argued it was unlikely that the teens were already predisposed to these kinds of mental health issues, according to NBC News. The study noted that the risk of psychosis did not spike for users between the ages of 20 and 33 and Dr. Kevin Gray, a professor of psychiatry at the Medical University of South Carolina who was not a part of the study, told NBC News that the increase in risk of psychosis likely had to do with brain development at different stages of life.
“There’s something about that stage of brain development that we haven’t yet fully characterized — where there’s a window of time where cannabis use may increase the risk of psychosis,” Gray said. “This study really puts a fine point on delaying cannabis use until your 20s may mitigate one of the most potentially serious risks.”
Another study from July 2023 found that marijuana addiction made individuals four times more likely to later be diagnosed with bipolar disorder with psychotic symptoms and two times more likely to be diagnosed with depression. Recreational marijuana use has been legalized in 24 states and Washington D.C., and 13 states have legalized the substance for medical use, according to CBS News.

Cigarettes kill nearly half a million Americans each year. Everyone knows it, including the Food and Drug Administration. Yet while the most lethal nicotine product remains on sale in every gas station, the FDA continues to block or delay far safer alternatives.
Nicotine pouches—small, smokeless packets tucked under the lip—deliver nicotine without burning tobacco. They eliminate the tar, carbon monoxide, and carcinogens that make cigarettes so deadly. The logic of harm reduction couldn’t be clearer: if smokers can get nicotine without smoke, millions of lives could be saved.
Sweden has already proven the point. Through widespread use of snus and nicotine pouches, the country has cut daily smoking to about 5 percent, the lowest rate in Europe. Lung-cancer deaths are less than half the continental average. This “Swedish Experience” shows that when adults are given safer options, they switch voluntarily—no prohibition required.
In the United States, however, the FDA’s tobacco division has turned this logic on its head. Since Congress gave it sweeping authority in 2009, the agency has demanded that every new product undergo a Premarket Tobacco Product Application, or PMTA, proving it is “appropriate for the protection of public health.” That sounds reasonable until you see how the process works.
Manufacturers must spend millions on speculative modeling about how their products might affect every segment of society—smokers, nonsmokers, youth, and future generations—before they can even reach the market. Unsurprisingly, almost all PMTAs have been denied or shelved. Reduced-risk products sit in limbo while Marlboros and Newports remain untouched.
Only this January did the agency relent slightly, authorizing 20 ZYN nicotine-pouch products made by Swedish Match, now owned by Philip Morris. The FDA admitted the obvious: “The data show that these specific products are appropriate for the protection of public health.” The toxic-chemical levels were far lower than in cigarettes, and adult smokers were more likely to switch than teens were to start.
The decision should have been a turning point. Instead, it exposed the double standard. Other pouch makers—especially smaller firms from Sweden and the US, such as NOAT—remain locked out of the legal market even when their products meet the same technical standards.
The FDA’s inaction has created a black market dominated by unregulated imports, many from China. According to my own research, roughly 85 percent of pouches now sold in convenience stores are technically illegal.
The agency claims that this heavy-handed approach protects kids. But youth pouch use in the US remains very low—about 1.5 percent of high-school students according to the latest National Youth Tobacco Survey—while nearly 30 million American adults still smoke. Denying safer products to millions of addicted adults because a tiny fraction of teens might experiment is the opposite of public-health logic.
There’s a better path. The FDA should base its decisions on science, not fear. If a product dramatically reduces exposure to harmful chemicals, meets strict packaging and marketing standards, and enforces Tobacco 21 age verification, it should be allowed on the market. Population-level effects can be monitored afterward through real-world data on switching and youth use. That’s how drug and vaccine regulation already works.
Sweden’s evidence shows the results of a pragmatic approach: a near-smoke-free society achieved through consumer choice, not coercion. The FDA’s own approval of ZYN proves that such products can meet its legal standard for protecting public health. The next step is consistency—apply the same rules to everyone.
Combustion, not nicotine, is the killer. Until the FDA acts on that simple truth, it will keep protecting the cigarette industry it was supposed to regulate.

Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. is urging health leaders across the planet to stop including mercury in vaccinations.
“Now that America has removed mercury from all vaccines, I call on every global health authority to do the same — to ensure that no child, anywhere in the world, is ever exposed to this deadly neurotoxin again,” he said.
Kennedy’s comments came in a video he recorded for the Minamata Convention on Mercury. The event is an international gathering aimed at preventing human contact with mercury, which, according to the World Health Organization (WHO), is one of the top 10 chemicals of major public health concern. The treaty, backed by the United Nations (UN), was first signed in 2013 by over 140 countries.
Kennedy noted that while the group’s goal is no doubt praiseworthy, it has not gone far enough in its efforts.
“Article 4 of the convention calls on parties to cut mercury use by phasing out listed, mercury-added products. But in 2010, as the treaty took shape, negotiators made a major exception. Thimerosal-containing vaccines were carved out of the regulation,” he recalled.
“The same treaty that began to phase out mercury in lamps and cosmetics chose to leave it in products injected into babies, pregnant women, and the most vulnerable among us,” he noted. “We have to ask: Why? Why do we hold a double standard for mercury? Why call it dangerous in batteries, in over-the-counter medications, and make-up but acceptable in vaccines and dental fillings?”
This past summer, Kennedy’s Advisory Committee for Immunization Practices launched a study to research the vaccine schedule for children. Among other recommendations, the committee advised the removal of thimerosal, a neurotoxic, mercury-containing preservative that had been used in flu shots.
Kennedy noted in his video message that “thimerosal’s own label requires it to be treated as a hazardous material and warns against ingestion,” adding that “there is not a single study that proves it’s safe. That’s why in July of this year the United States closed the final chapter on the use of thimerosal as a vaccine preservative, something that should have happened years ago.”
Kennedy further explained that thimerosal is “a potent neurotoxin, a mutagen, a carcinogen, and an endocrine disrupter” while noting that “safe alternatives” already exist.
“Manufacturers have confirmed that they can produce mercury-free, single dose vaccines without interrupting supply. There is no excuse for inaction or holding stubbornly to the status quo,” he exclaimed. “Now that America has removed mercury from all vaccines, I call on every global health authority and every party to this convention to do the same.”
“Let’s honor and protect humanity, and our children, and creation from mercury,” he concluded.
The Minamata Convention on Mercury went into effect in August 2017. It was initially approved by the Intergovernmental Negotiating Committee in Geneva, Switzerland, in January 2013. It was adopted in October 2013 at a Diplomatic Conference in Kumamoto, Japan. Per its website, it is named “after the bay in Japan where, in the mid-20th century, mercury-tainted industrial wastewater poisoned thousands of people, leading to severe health damage that became known as the ‘Minamata disease.’”
