According to Premarket Tobacco Product Applications (PMTA) For ENDS, FDA requires manufacturers and importers submit testing reports of chemicals, additives, Nicotine concentration, and a full toxicological and pharmacological assessment for health risks of new tobacco products. In EU countries, such as UK, manufacturers and importers of E-Cigarettes also need to submit test reports of components, ingredients, additives, and toxicological assessment, according to EU Tobacco Products Directive (TPD) on E-Cigarettes, to assess the public health risks.
Under the background of more strict supervision of E-Cigarettes marketing in global market, toxicological assessment of ENDS is essential for E-Cigarettes products marketing. As one of the earliest independent testing organizations in E-Cigarettes test field, PTS Testing Service Lab has developed complete in vitro toxicological assessment methods for E-Cigarettes, according to Health Canada official methods.
