Is Cannabis Safe? Insights from Harvard Health Studies

The use and legal status of marijuana have evolved significantly, prompting various studies and discussions on its safety and health implications. One such exploration, by Alvin Powell, a Harvard Staff Writer, highlights the paradox in cannabis use: widespread public use but limited medical understanding. This article delves into several Harvard Health studies to provide a nuanced view of cannabis use, its potential risks, and safer consumption methods.

Firstly, a Harvard Health article advises against smoking cannabis, which can inflame the lungs. Instead, alternatives like under-the-tongue tinctures, edibles, topical products, or dry herb vaporizers are recommended. It also cautions against holding cannabis smoke in the lungs, as it offers no enhanced effect but can irritate the lungs.

A study on the cognitive effects of long-term cannabis use indicates a decline in IQ points and processing speed, especially with frequent use. This finding suggests a potential causative link between cannabis use and cognitive impairment.

Concerning cardiovascular health, a Harvard research review published in the Journal of the American College of Cardiology shows that cannabis smoking can increase heart rate and blood pressure. This is particularly risky for individuals with heart disease. Furthermore, a study led by Stanford Medicine researchers links marijuana use to an increased risk of heart disease and heart attacks.

The growing acceptance of medical marijuana, especially among older adults, is also addressed. While the stigma around cannabis use has decreased, especially for medical purposes, concerns about its safety remain. This is evident in reports of hallucinations, kidney damage, seizures, and even death associated with certain cannabis products.

Finally, the issue of cannabis dependence and withdrawal is explored. Contrary to some beliefs, withdrawal from cannabis can include symptoms like aggression, irritability, anxiety, and physical discomfort.

In conclusion, while cannabis is increasingly accepted for both medical and recreational use, its safety and health effects are still subjects of debate and research. As studies continue, it is essential for users to remain informed and cautious about their cannabis consumption choices.
