An increasing number of people are calling into Poison Control centers after accidentally consuming too much cannabis, in the form of edibles, vapes, cannabis flower, and tinctures, according to a report in the journal JAMA Open.

28,630 people called Poison Control between January 2017 and December 2019, according to data collected from the National Poison Data System. Adults 21 or older were most likely to call, and 38.5% of calls from poisoned adults were due to manufactured cannabis products like edibles and vapes.

34.5% of calls concerned patients in the 10 to 20 age range, while 27% of calls concerned patients under 10.

The majority of calls came from healthcare facilities on behalf of reportedly poisoned people, not individuals’ homes.

The report didn’t specify the symptoms callers felt when they or their healthcare providers alerted Poison Control, but common negative reactions to THC, the psychoactive component of cannabis, include a racing heart, nausea, vomiting, paranoia, dizziness, and impaired thinking and coordination, Insider previously reported.

As more states legalize cannabis for adult and medicinal purposes, reports of overuse could increase, the researchers who penned the report wrote. They said non-flower cannabis products, like vapes, tinctures, and edibles are of heightened concern because they were the most common causes for reported poisonings, and previous evidence suggests these products could have dangerous additives.
