The death toll here in the United States from a mysterious vaping illness has now risen to five.
The sickness linked to vaping, which includes symptoms like chest pain, shortness of breath and vomiting, has sprung up in 450 cases across the country, puzzling health officials.
Though vaping has been identified as a common denominator in the illnesses, it remains unclear what exactly is causing the outbreak.
According to the LA Times, one of the vaping death victims was a person over 55 with other health problems.
While it's not yet clear what exactly is causing these illnesses, it seems to affect people who are vaporizing THC and CBD oils. The culprit, according to some experts, are chemicals like vitamin E acetate that are used to emulsify THC and CBD oils in illegal, unregulated vaporizers.
Health officials have warned Americans to avoid using vapes and e-cigarettes until they get a better handle on the issue.
