Is Marijuana Safe? Exploring the Risks and Realities


Marijuana, a substance both celebrated and scrutinized, poses various questions regarding its safety and health implications. With increasing legalization, understanding its effects on health becomes paramount.

Concerns about marijuana’s impact on memory have been raised, especially due to its psychoactive compound, THC, binding to receptors in memory-related brain regions such as the hippocampus, amygdala, and cerebral cortex. Harvard Health highlights the potential cognitive risks associated with long-term marijuana use, which could be of particular concern for those using it for medical or recreational purposes​​​​.

Heart health is another area of apprehension. Studies suggest that marijuana use can lead to an increased heart rate and blood pressure, posing risks for individuals with heart conditions. Research indicates a heightened risk of heart attack following marijuana consumption and a possible link between its use and atrial fibrillation​​​​.

The physical effects of marijuana smoke are often compared to those of tobacco. Both contain harmful toxins, irritants, and carcinogens, with marijuana smoke reportedly having higher levels of certain carcinogens. This poses potential risks for lung health and cancer, challenging the perception of marijuana as a safer alternative to tobacco​​.

Interestingly, a study involving nearly 35,000 participants found that those smoking cannabis more than once a month were more likely to experience a heart attack. This finding underscores the potential cardiovascular risks associated with even moderate marijuana use​​.

While marijuana’s legalization gains momentum, it’s crucial to approach its use with caution. Notably, experts advise against smoking marijuana, which can inflame the lungs, suggesting alternative methods like under-the-tongue tinctures, edibles, topical products, or dry herb vaporizers. Additionally, it’s recommended not to hold marijuana smoke in the lungs for more than a few seconds, as this doesn’t enhance its effects but rather increases lung irritation​​.

The prevalence of marijuana use among teenagers also raises concerns. In 2019, 37% of high school students in the United States reported having tried or used marijuana at least once, with 22% using it in the preceding 30 days. These figures saw a significant drop in 2020 and 2021, with lower rates continuing into 2022​​.

In light of these findings, it’s evident that while marijuana may offer some benefits, its potential risks cannot be overlooked. As legalization spreads, further research and public education are essential to ensure informed decisions about its use.
