Studies link cannabis use disorder to increased risk of stroke, Atrial fibrillation

Marijuana use among young people is on the rise more so in locations where cannabis is legal. According to a Virginia study young people who reported using cannabis frequently had a higher risk of having a stroke. In addition, an Oklahoma study links people diagnosed with cannabis use disorder to greater hospitalisation with Atrial fibrillation.

The two new preliminary studies shall be presented at the American Heart Association’s Scientific Sessions 2019 — November 16 -18 in Philadelphia.  In addition, the study linking cannabis use disorder to an increased risk of stroke will be published in Stroke, a Journal of the American Stroke Association, a division of the American Heart Association.

Young people who used cannabis frequently and also smoked cigarettes or used e-cigarettes were three times more likely to have a stroke compared to non-users.

The study also showed that cannabis users who did not use tobacco products but reported using cannabis for more than 10 days a month were nearly 2.5 times more likely to have a stroke compared to non-users.

The cannabis users were also more likely to be heavy drinkers, current cigarette users and e-cigarette users, which may have also influenced their risk, even though the researchers adjusted for those factors in their analysis.

Participants in the study included more than 43,000 adults aged 18 to 44, of whom nearly 14% reported using cannabis in the last 30 days. Compared with non-users, marijuana users were often younger, non-Hispanic white or black were less likely to be college graduates and were often physically active.

“Young cannabis users, especially those who use tobacco and have other risk factors for strokes, such as high blood pressure, should understand that they may be raising their risk of having a stroke at a young age,” said lead study author Tarang Parekh, M.B.B.S., M.S., a health policy researcher at George Mason University in Fairfax, Virginia. “Physicians should ask patients if they use cannabis and counsel them about its potential stroke risk as part of regular doctor visits.”

The study was observational and did not examine the biological mechanism connection between stroke and cannabis use, so it identified a potential link, rather than proving cause and effect. The data analyzed was from the behavioral risk factor surveillance system (BRFSS) (2016-17), a nationally representative cross-sectional survey collected by the U.S. Centers for Disease Control and Prevention.

Cannabis use disorder linked to serious heart rhythm abnormalities (Poster Presentation Mo2053)

People diagnosed with cannabis use disorder had a 50% greater risk of being hospitalized for an arrhythmia, a disorder of the heart’s rhythm, compared to non-users. Cannabis use disorder is characterized by frequent, compulsive use of marijuana, similar to alcoholism.

In this study, young African American men with the disorder, between 15 to 24 years of age, had the greatest risk of being hospitalized for arrhythmia, although cannabis use disorder was more common among white men, 45 to 54 years of age.

While some arrhythmias are benign, others can be life-threatening. “The effects of using cannabis are seen within 15 minutes and last for around three hours. At lower doses, it is linked to a rapid heartbeat. At higher doses, it is linked to a too-slow heartbeat,” said Rikinkumar S. Patel, M.D., M.P.H., resident physician in the department of psychiatry at the Griffin Memorial Hospital in Norman, Oklahoma.

“The risk of cannabis use linked to arrhythmia in young people is a major concern, and physicians should ask patients hospitalized with arrhythmias about their use of cannabis and other substances because they could be triggering their arrhythmias,” said Patel.

“As medical and recreational cannabis is legalized in many states, it is important to know the difference between therapeutic cannabis dosing for medical purposes and the consequences of cannabis abuse. We urgently need additional research to understand these issues,” said Patel.
