I know it smells good, but you might wanna put it out. The incense, I mean:
Burning incense may create a sweet scent, but regularly inhaling the smoke could put people at risk of cancers of the respiratory tract, researchers reported Monday.
In a study of more than 61,000 ethnic Chinese living in Singapore who were followed for up to 12 years, the investigators found a link between heavy incense use and various respiratory cancers. […]
The researchers found that incense use was associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. However, they observed no overall effect on lung cancer risk.
Those who used incense heavily also had higher rates of a type of cancer called squamous cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The risk was seen in smokers and nonsmokers.
Study participants who used incense in their homes all day or throughout the day and night were 80 percent more likely than non-users to develop squamous cell carcinoma of the entire respiratory tract.
The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. (emphasis mine)
Incense: yet another surprising substance that weed is safer than.
