A new Truth Initiative survey of 15-24-year-olds finds that two-thirds (68%) of disposable e-cigarette users threw their empty disposable e-cigarettes in the trash, 13% dropped them in regular recycling bins, 9% littered them on the ground, and 8% sent them to electronic recycling facilities
Nicotine, BaP, humectants (glycerol, propylene glycol, and triethylene glycol), flavours (methyl salicylate, ethyl salicylate, eugenol, diphenyl ether, cinnamaldehyde, menthol, coumarin, and camphor), internal standards (n-heptadecane, 3,4-methylenedioxyacetophenone, and 1,3-butanediol), and solvents (cyclohexane, propan-2-ol, benzene, and methanol) were procured through Sigma Aldrich, USA having a minimum purity of 99.0%
Another limitation of the study is that the participants were mostly white and in their 60s and 70s, so the smoking patterns collected in the study reflect only a particular set of age groups in the United States
