With five more states on the ballot to legalize marijuana, more stories are being published about marijuana consumption than ever. Just to keep things in the arena of fact and far away from fiction, here are some headlines and the fact-check to keep things on track.

An emergency room doctor in rural Ontario is getting slammed for a viral tweet in which she claimed weed edibles kill children.
On Friday, Merrilee Brown tweeted, “In ER last night I treated someone for a cannabis induced psychosis from cannabis ‘edibles,’ in this case, a chocolate bar. She ate one piece of the 16 piece bar. That piece had 20g of THC equivalent to 20 joints! Edibles are often so concentrated that they can be fatal in kids.”
Several misleading and false claims here. There is no evidence that cannabis ingestion has ever killed anyone. Even the DEA (Drug Enforcement Agency) confirms that there are no reported cases of overdose from marijuana EVER.
For another, it doesn’t make sense that a single piece of the chocolate bar, which she said was a total of 225 grams, could contain 20 grams of THC. (THC doses in edibles are generally measured in milligrams.)
Rebecca Haines-Saah, a public health policy expert and professor at the University of Calgary, told VICE there’s no evidence to suggest weed directly causes psychosis or illnesses like schizophrenia. There have been studies that have shown links between cannabis use and the early onset of schizophrenia, particularly in people with pre-existing conditions or a family history of mental illness, but those links are far from concrete. Haines-Saah told VICE it’s far more likely the patient Brown treated was simply having a bad trip, including anxiety, paranoia, or hallucinations.
Bonni Goldstein, who has been a pediatrician for 28 years, including 13 as a pediatric emergency room physician, told VICE edible ingestion creates more of a psychoactive effect than just smoking because the THC goes through the liver and creates a metabolite called 11-hydroxy-THC. She pointed to a case out of Colorado where doctors described an 11-year-old’s death from myocarditis (heart inflammation) as a cannabis-associated death because THC was in his system. But those doctors later admitted they couldn’t prove cannabis was the cause of death. Goldstein said THC and CBD are anti-inflammatories. “There’s nothing in the literature to support the word ‘fatal’ in this doctor’s tweet,” said Goldstein.
After negative backlash, the pediatrician did back peddle, claiming she may have misread the label and that she is “no expert” in cannabis.
So, this information is: FALSE
Several articles claim that high content THC vaping can cause psychosis and schizophrenia in young people.
The THC found in marijuana causes most people to feel euphoric and relaxed. Some people say that they experience heightened sensory perception (colors seem brighter), laughter, an altered perception of time, and increased appetite. Others still may experience anxiety, fear, distrust, or paranoia. This might happen if someone over consumes THC. People consuming far too much THC might also experience temporary psychosis which might include hallucinations and delusions, These are unpleasant but temporary reactions are not the same as long term psychosis such as schizophrenia. Factors such as genetic disposition, age of first use, overuse of THC all influence the results of long term use. Most research and scientific evidence point to potential risk for psychosis in those with a preexisting genetic vulnerability or other vulnerability. There’s also consideration for causation and correlation. Many people who already have mental illness use cannabis to self-medicate. Meaning they had the conditions before they started consuming cannabis, not after.
In addition, research using longitudinal data from the National Epidemiological Survey on Alcohol and Related Conditions examined associations between marijuana use, mood and anxiety disorders, and substance use disorders. After adjusting for various confounding factors, no association between marijuana use and mood and anxiety disorders was found. The only significant associations were increased risk of alcohol use disorders, nicotine dependence, marijuana use disorder, and other drug use disorders.
In addition, most experts now distinguish between the “new cannabis” — legal, highly potent, available in tabs, edibles and vapes — and the old version, a far milder weed passed around in joints. Levels of THC, the chemical that produces marijuana’s high, have been rising for at least three decades, and it’s now possible in some states to buy vape cartridges that contain mostly THC.
If you’re concerned, there are some steps you can take to eliminate any worry. First, since there’s a suggested genetic component in mental illness, find out if it’s common in your family to see if you are vulnerable. Most medical marijuana clinics will ask for your medical history and current conditions before approving you for medical marijuana.
