The widespread legalization of marijuana, both for medical and recreational use, has been a significant development in recent years. As of February 24, 2020, 33 states in the United States have legalized marijuana for medical purposes, and 11 states have allowed its recreational use. However, this increasing legality doesn’t necessarily equate to safety. Alvin Powell, a Harvard Staff Writer, delves into this complex issue, highlighting the paradox that exists between public usage and medical understanding of marijuana.
Marijuana, derived from the Cannabis sativa plant, has been used for around 6,000 years. Despite its long history, concerns about its impact on health persist. Smoking marijuana, the fastest way to feel its effects, exposes users to many harmful substances. These include toxins, irritants, and carcinogens, which are also found in cigarette smoke – known contributors to heart disease and cancer. This raises questions about the long-term health implications of marijuana use.
It’s also important to consider the heart-related risks associated with marijuana. The substance can cause an accelerated heart rate and increased blood pressure, which are particularly dangerous for individuals with heart disease. Research suggests that the risk of heart attack may multiply several times in the hour following marijuana use. A connection has also been found between marijuana and atrial fibrillation, the most common type of irregular heartbeat.
Further complicating matters, a large study led by Stanford Medicine researchers indicates a heightened risk of heart disease and heart attack among marijuana users. This study also revealed that THC, the psychoactive component in cannabis, can cause inflammation in blood vessel cells and contribute to atherosclerosis in laboratory mice.
The risks extend beyond heart health. Marijuana smoke contains high concentrations of carcinogens, potentially higher than those found in tobacco smoke. This similarity raises concerns about the long-term effects on lung health.
Given these risks, it’s advised to avoid smoking cannabis, especially for individuals with lung issues. Alternative methods of consumption, like under-the-tongue tinctures, edibles, topical products, or dry herb vaporizers, are suggested as safer options. However, users should remain cautious and informed about the potential health implications of these methods as well.
In conclusion, while the use of marijuana might be becoming more accepted and legal, it’s crucial to approach its use with caution and an understanding of the potential health risks involved. As research continues, it is hoped that a clearer picture of marijuana’s safety profile will emerge.
