There are many types of beliefs in the society about marijuana. Some people consider it harmless, while some consider it harmful. Now a new study has issued another warning regarding the consumption of marijuana. According to the study, the risk of head and neck cancer increases in those who consume marijuana regularly.
A study conducted in America found that people who consume marijuana regularly are three to five times more likely to have head and neck cancer than normal people. In this study, 20 years of data was analyzed, which included more than 1 lakh 16 thousand American adults. Some of these people had the problem of marijuana addiction.
Expert statement
The lead author of the study, Dr. Niels Kokot, said that this is the first major study of its kind, in which head and neck cancer has been directly linked to the consumption of marijuana. He said that it is important to know which behaviors increase the risk of head and neck cancer, so that people can avoid them. According to the study, the consumption of marijuana increases the risk of cancer of the mouth, throat, larynx, salivary glands and oropharynx (which includes the tongue, tonsils and the back wall of the throat). However, the study did not state how the marijuana was consumed, such as smoking or eating.
Cause of cancer
Experts say that marijuana smoke contains some elements that are also found in tobacco smoke and these can cause cancer. Apart from this, some elements present in marijuana can activate enzymes that promote cancer. However, the study also has some limitations. For example, people themselves have reported the consumption of marijuana, so its exact amount could not be known. Apart from this, the people included in the study have been compared on the basis of age and gender, but other factors such as alcohol and tobacco consumption have not been taken into account.
Need for more research
Experts say that more research is needed after this study. But, the results of this study are quite worrying and people need to be cautious about the consumption of marijuana. Laws are changing in many countries regarding marijuana and it is being legalized. But, after this study, people need to be careful about the consumption of marijuana and should be aware of its potential dangers.
