In order to accurately assess benefits and harms of e-cigarettes, many studies have been conducted to determine the chemical composition of both e-liquids and their vapors. One study conducted by FDA in 2009 showed that cancer-causing compounds found in tobacco were also found in some e-cigarette cartridges, along with other toxins, one of them being diethylene glycol – a toxic chemical used in anti-freeze
