Is Cannabis Really Safe? Unraveling the Complexities of Its Legalization and Use


As cannabis legalization continues to expand across the United States, the question of its safety remains a topic of debate and uncertainty. With nearly 70% of states permitting medical cannabis use and an increasing number embracing recreational legalization, understanding the complexities surrounding cannabis is more important than ever.

A recent CBS News/YouGov survey highlights a growing trend: two-thirds of Americans support the legalization of recreational marijuana. This shift in public opinion is significant, yet it does not necessarily imply that cannabis is without risks. Neuroscientist Yasmin Hurd emphasizes that legalization does not equate to a clean bill of health for cannabis. In fact, the debate over cannabis’s safety is far from settled, with many aspects still under scientific scrutiny.

Harvard Health and Johns Hopkins have explored the risks and benefits of legalized cannabis. Their research suggests that while there are certain advantages to legalizing cannabis, such as regulation and taxation, the scientific community is still catching up with the rapidly evolving social norms and product availability.

One of the significant concerns is the impact of cannabis on lung health. Smoking cannabis, according to Harvard Health, can expose users to various toxins and carcinogens, similar to those found in cigarette smoke. This raises questions about its potential role in heart disease and cancer. Additionally, the environmental impact of cannabis cultivation, particularly in terms of water usage and land use, cannot be overlooked. The UC Berkeley Cannabis Research Center notes that illegal outdoor cannabis cultivation often involves unauthorized water sourcing and the use of toxic pesticides, further complicating the environmental aspect.

Furthermore, the effects of cannabis on heart health are a growing concern. Studies suggest that marijuana use can lead to an increased heart rate and higher blood pressure, posing risks for individuals with heart conditions. The debate extends to the realm of mental health as well, with the CDC outlining both short- and long-term effects on the brain.

In light of these concerns, experts advise caution in cannabis use. Options like under-the-tongue tinctures, edibles, topical products, or dry herb vaporizers are recommended over smoking. When smoking is chosen, it’s advised not to hold the smoke in the lungs for more than a few seconds to minimize lung irritation.

As society continues to navigate the legalization and usage of cannabis, it becomes clear that while there are benefits, there are also undeniable risks and areas where further research is crucial. The journey towards understanding cannabis’s full impact on health and the environment is ongoing, with many questions still unanswered.
