Is Cannabis Truly Safe? Exploring the Risks and Effects on Health

With the increasing legalization and use of cannabis, questions arise about its safety and health impacts. Harvard Health and other research institutions have shed light on various aspects of cannabis use, raising important considerations for users.

A Harvard Gazette article discusses the complex nature of cannabis use and addiction. Contrary to alcohol, where even infrequent use can be problematic, cannabis-related issues often arise from daily, multiple-times-a-day use. This distinction underscores the need for a deeper understanding of what constitutes heavy use in the context of cannabis.

Harvard Health advises on safe cannabis use. Recommendations include avoiding smoking, which can inflame the lungs, and opting for alternatives like tinctures, edibles, or vaporizers. The advice also cautions against holding smoke in the lungs for extended periods and refraining from driving for at least four hours after use.

However, there are heart-related risks associated with marijuana. Studies highlighted by Harvard Health show that marijuana can cause increased heart rate and blood pressure, posing dangers for those with heart disease. The risk of heart attack is notably higher in the hour after smoking marijuana, and there’s a reported link between marijuana use and atrial fibrillation.

Concerning cognitive effects, Harvard Health explains how THC, marijuana’s main psychoactive component, can impact memory. This is due to THC’s interaction with brain regions essential for memory formation. Persistent cognitive impairments have been observed in long-term cannabis users, with more significant effects noted in frequent users.

Stanford Medicine research, as reported by Stanford News, found an increased risk of heart disease and heart attack in marijuana users. The study also indicated that THC can cause inflammation in blood vessel lining and contribute to atherosclerosis in laboratory mice.

Despite its growing legality, the debate about cannabis safety continues. As neuroscientist Yasmin Hurd pointed out in a Harvard Gazette interview, legalization does not equate to safety, implying that further research is needed to fully understand the implications of cannabis use.

In conclusion, while cannabis may offer certain benefits and is becoming more legally accessible, its safety and health impacts remain areas of active research and debate. Users should consider the potential risks and make informed decisions about their use.
