The Indiana State Department of Health reported the state's first vaping death.
The exact cause of the illness remains unknown, but investigators think that it is likely related to a chemical exposure, instead of an infectious agent. As a result, the FDA issued a warning in July 2009 on the health risks posed by vaping and, like the WHO, called for clinical studies to help determine whether e-cigarettes are safe for their intended use.
"The FDA appreciates the continued collaboration between our federal and state public health partners to get to the bottom of these distressing incidents and gather more information about any products or substances used".
Concerns over marijuana vaping-related illnesses continue to mount, as USA health officials on Friday again urged people to stop vaping until it's determined why some consumers are coming down with serious breathing illnesses. Whether the oils in the lungs came from the e-cigarettes, the body, or somewhere else entirely, is up for debate. The oil is a key line of enquiry in the state's investigation but the FDA has said the substance has not been found in all identified samples. Some reported using both THC and e-cigarettes while a smaller group reported using only nicotine, the CDC said. The CDC and FDA are working together with local and state health departments on standardizing how these cases are identified and reported, as well as supporting state probes and analyzing samples collected from patients. MDH said if you're experiencing symptoms, avoid using e-cigarettes and other vaping products.
However, as of now, federal officials have said that from the samples that were examined, they could not find a single common substance.
Many patients reported vaping cannabis, but some said they had only inhaled nicotine products.
