Pot users chose to use it in a variety of ways, including smoking, vaping or consuming it in edible products, the investigators found.
Non-users seemed to have better blood sugar control overall. HbA1C levels — a blood test that estimates two to three months of blood sugar levels — were slightly higher in people who used marijuana.
However, the study only found an association and could not prove a cause-and-effect relationship.
Dr. Joel Zonszein, director of the clinical diabetes program at Montefiore Medical Center in New York City, said, “I was not surprised that the use of cannabis is associated with DKA. Individuals with type 1 diabetes need to be engaged with their disease and manage insulin dosing constantly, even those on the pump with closed loop systems.”
Zonszein said that getting high on marijuana may impair people’s ability to give themselves the correct insulin dose.
“This study is a warning of the serious and potentially life-threatening ‘side effect’ of marijuana. This is particularly important due to the ever expanding use of cannabis after its legalization,” Zonszein added.
