Is Marijuana Use Risky for Heart Health?


Understanding the complexities surrounding marijuana use and heart health is increasingly important, especially with the growing legalization for both medical and recreational purposes. Harvard Health, Johns Hopkins, and other notable institutions have delved into this topic, providing valuable insights.

Although marijuana, derived from the Cannabis sativa plant, has been used for over 6000 years, its impact on health, particularly on the heart, is still a subject of ongoing research. Harvard Health indicates that marijuana smoke contains many of the same harmful substances found in cigarette smoke, which is a known contributor to heart disease and cancer.

Is Marijuana Use Risky for Heart Health?

For those using cannabis, it’s advised to avoid smoking, as this can inflame the lungs. Alternative methods such as under-the-tongue tinctures, edibles, topicals, or dry herb vaporizers are considered safer. Moreover, holding marijuana smoke in the lungs for more than a second or two is discouraged, as it doesn’t increase efficacy but may irritate the lungs further.

The heart-related risks of marijuana are significant. It can cause an accelerated heart rate and increased blood pressure, posing dangers particularly for individuals with heart disease. Research, including that from Harvard Health, suggests that the risk of heart attack may be several times higher in the hour after smoking marijuana. Additionally, links between marijuana use and atrial fibrillation have been found.

Despite its legalization in many states for medical and recreational purposes, the safety of marijuana is still questioned. For instance, a study by Harvard staff writer Alvin Powell highlights the paradox of widespread public use of marijuana against limited medical knowledge about it. According to Harvard Gazette, frequent marijuana smokers are more likely to experience a heart attack before the age of 50, a condition known as a premature heart attack.

Neuroscientist Yasmin Hurd points out the mental health risks associated with cannabis use, particularly for those with a family history of psychosis or schizophrenia. This caution is echoed by Harvard Medical School, emphasizing the risks of cannabis in triggering psychotic symptoms and potentially exacerbating issues related to psychosis and schizophrenia.

It’s essential to understand the legal distinctions in cannabis products. By law, marijuana is defined as a cannabis plant with more than 0.3% THC, whereas hemp contains 0.3% or less THC. This difference is critical in evaluating the potential intoxicating effects and health risks associated with these products.

In conclusion, while the use of marijuana might be increasingly accepted legally, it’s imperative to approach its use with caution, particularly regarding heart health. More research is needed to fully understand the implications of marijuana use on heart health and overall well-being.
