Why Increased Pot Use In Colorado Is Sending More People To The Hospital

Reefer madness isn’t a thing. But a new study out Tuesday is the latest to show that pot use, especially with edibles, can sometimes cause health problems serious enough to prompt a trip to the hospital. It found that people in Colorado have increasingly sought emergency care for cannabis-related symptoms like anxiety, rapid heartbeat, and a strange syndrome characterised by intense vomiting since recreational cannabis was legalised in the state.

Colorado passed an amendment to legalise cannabis fully in 2012, and began to allow sales of it in 2014. So the researchers behind the study, published in Annals of Internal Medicine, looked at medical records from patients who visited the emergency department of the UCHealth University of Colorado Hospital from 2012 to 2016. These visits had all been initially diagnosed as related to cannabis use, with nearly 10,000 such visits documented between those years.

During that time period, they found, cannabis-related visits shot up more than threefold. Roughly a quarter of these visits (27 per cent) could be directly attributed to using cannabis, they also estimated. And while people more often ended up in the hospital from smoking pot, pot edibles were more likely to cause problems.

But a new case study suggests that, under the right circumstances, pot can indeed cause serious health problems. According to the new paper, a 70-year-old Canadian man with preexisting cardiovascular disease suffered a heart attack soon after treating himself to a THC lollipop.”]

“About 10 per cent of cannabis-related ED visits were associated with edible forms of weeds, but only 0.32 per cent of total cannabis sales were for edible products,” lead author Andrew Monte, associate professor of emergency medicine and emergency toxicology at the University Of Colorado School Of Medicine, told NBC News. “That’s 33 times higher than what we expected.”

Edibles also seemed to cause more serious side-effects. Eighteen per cent of visits related to edibles featured acute psychiatric symptoms—including panic attacks or bouts of psychosis—compared to 10 per cent of visits for inhaled cannabis, for instance. Edibles were also more often associated with intoxication (48 per cent vs. 28 per cent for inhaled pot) and cardiovascular symptoms (8.0 per cent vs. 3.1 per cent).

At the same time, smoking pot was associated with a greater rate of people needing hospitalisation for their symptoms. One major reason was the higher incidence of cannabinoid hyperemesis syndrome (CHS), a condition that causes horrible stomach pain, repeated vomiting, and the compulsion to take hot water showers (sufferers say the hot water soothes their symptoms).

Because the findings were based on visits to a single, if large, hospital in Colorado, we don’t know for sure yet that pot-related ER visits are on the rise everywhere that cannabis is becoming legalised. The observational nature of the study also can’t tell us if someone’s symptoms, including psychosis, were actually caused by cannabis use, only that the two things are linked. Research has gone back-and-forth on whether people with a predisposition to mental illnesses like schizophrenia are more likely to develop psychiatric symptoms if they use cannabis.

That said, it’s definitely true that most people who use cannabis will never go to the ER as a result. CHS in particular is thought to be incredibly rare, seemingly only happening in people who use cannabis heavily, and its frightening symptoms go away as soon as the person stops using cannabis.

But the findings do suggest that people’s unfamiliarity with edibles, which can take hours to fully kick in, can lead them to take more than they should and make them sick, the authors said. They added that more needs to be done to study the potential harms of edibles and cannabis generally, including its connection to mental health problems.
