On August 14, according to a report by CNN, a survey from the Journal of the American Medical Association Network Open revealed that the majority of respondents (44%) believe that smoking marijuana is safer than smoking tobacco. Additionally, they also believe that the risks of inhaling secondhand marijuana smoke for both adults and children are lower than those of cigarette smoke. However, Dr. Beth Cohen, the lead author of the study and a medical professor at the University of California, San Francisco (UCSF), as well as the co-director of the UCSF Inpatient Investigative Methods and Epidemiology Program, argues that these beliefs are not accurate.

A study published in the Journal of the American Medical Association Network Open examined the growing acceptance of marijuana among a sample of over 5,000 individuals with an average age of 50. The study aimed to understand their attitudes towards the safety of marijuana use compared to tobacco use. Participants were also asked whether they believed secondhand smoke from marijuana or tobacco could be harmful.

According to a study conducted in 2017, 2020, and 2021, the positive perception of marijuana among people has been steadily increasing. By the final year of the survey in 2021, over 44% of respondents believed that marijuana was somewhat or even safer, while only 25.5% considered cigarettes to be safer.

In light of the potential harm it may cause to others (secondhand smoke), over 40% of individuals consider marijuana smoke to be safer, while only 23% opt for tobacco.

However, experts in the field do not agree with this trend. Carol Boyd, the founding director of the Center for Drug, Alcohol, Smoking, and Health Research at the University of Michigan-Ann Arbor, stated that marijuana smoke contains "a significant amount of toxins and tar," which could potentially harm the lungs.

Boyd stated:

I am unable to comment on the dangers, but if an individual is in a confined space with marijuana users, the presence of marijuana components may be detected in their urine. They may also experience other physiological effects of marijuana, including increased heart rate and a sense of excitement.

Boyd believes that comparing the health risks of consuming marijuana and tobacco is of little significance. All forms of smoking have irritating effects on the respiratory system, he commented.

In an era where humanity breathes polluted air, being smoke-free is beneficial.

Research on marijuana has been hampered by its illegal status in many states across the United States (currently still the case). Furthermore, the federal government has historically imposed strict regulations on the study of marijuana. These factors have posed significant challenges to the investigation of marijuana use.

With an increasing number of states legalizing marijuana for recreational use, researchers are now delving further into exploring the consequences of long-term cannabis consumption.

However, the current research shows that marijuana cigarettes indeed have some advantages compared to regular cigarettes, Boyd further explained.

It is commonly believed that frequent marijuana consumption is associated with chronic bronchitis, pharyngitis, and bronchial inflammation. Despite the presence of carcinogens in marijuana smoke, such as benzopyrene and benzanthracene, it seems that smoking marijuana does not appear to cause lung cancer.

In addition, individuals who consume marijuana tend to take deep breaths and hold the smoke in their lungs for extended periods of time. According to the American Lung Association, this can "result in increased exposure to tar with each breath.

Consuming marijuana can impair the lungs' first line of defense against infection, killing cells that help remove dust and bacteria, and leading to increased mucus formation.

The American Lung Association has stated that the consumption of marijuana can also suppress the immune system and potentially expose users to a particular type of mold that can grow on cannabis.

While further research is needed to understand the impact of marijuana consumption on the lungs, as well as the health effects of second-hand marijuana smoke, Cohen asserts that the current knowledge is worrisome.

She said:

I am not opposed to marijuana; I simply hope that people can make informed decisions. Even if further research indicates that marijuana smoke is relatively less harmful compared to tobacco smoke, it does not necessarily mean that it is completely safe.
