The public needs high-quality information about cannabis, which can help counterbalance the proliferation of rumor and false claims about the health effects of cannabis products.

While some studies have linked the chemicals of cannabis to a risk for heart attack, much remains unknown about THC’s effects on the cardiovascular system. Here are the truths of what is known and what research has provided in an updated analysis of cannabis and the risk for cardiovascular effects.

A 2017 study published in the Journal of Thoracic Disease stated that due to the rise of the recreational use of THC, researchers might be underestimating cannabis’ risk factors on the human body as well as the benefits.

Since cannabis continues to be listed as a Schedule 1 controlled substance, many organizations like the American Heart Association (AHA) have encouraged the Drug Enforcement Administration to review its designation and how it might hinder research. In August 2020, they explained in the journal Circulation:

“Because of the rapidly changing landscape of cannabis laws and marijuana use, there is a pressing need for refined policy, education of clinicians and the public, and new research. Laws should be harmonized in ways that limit confusion and better reflect the existing science behind cannabis, starting in the United States at the federal level with removal of cannabis from Schedule 1 of the US Controlled Substances Act, followed by a proactive approach to labeling that standardizes concentrations of THC and CBD content.”
