“Direct Dripping”: A High Temperature, High Formaldehyde Emission Electronic Cigarette Use Method.
Nicotine Tob Res. 2015 Apr 11. pii: ntv080. [Epub ahead of print]
 
Electronic cigarettes electrically heat and vaporize a liquid solution to produce an inhalable nicotine-containing aerosol. Normally the electronic heater is fed the liquid via an automatic wick system. Some ECIG users however, elect to directly drip liquid onto an exposed heater coil, reportedly for greater vapor production and throat hit. Use of such “direct drip atomizers” (DDAs) may involve greater exposure to non-nicotine toxicant due to the potentially higher temperatures reached by the coil. In this study we examined nicotine and volatile aldehyde (VA) emissions from one type of DDA under various use scenarios, and measured heater temperature.
 
Due to higher temperatures attained, DDAs are inherently likely to produce high toxicant emissions. The diversity of ECIG use methods, including potential off-label methods, should be considered as ECIG regulatory efforts proceed.
