5. Juulpod Juice - Ingredients
Our ingredients include glycerol, propylene glycol, natural oils, extracts and flavor, nicotine and benzoic acid.
Glycerol and Propylene Glycol have commonly used humectants in vaporization liquids, and also used in a number of consumer products like toothpaste.
Benzoic Acid is a naturally occurring acid found in the tobacco plant, which is a part of our proprietary formulation that makes JUUL the ultimate vaping experience.
As a policy, our development and manufacturing process does not add diacetyl and acetylproprionyl (or 2,3-pentanedione) as flavor ingredients.
Nicotine content: 0.7mL with 5% nicotine by weight (59 mg/mL per pod, ~ content of a pack of cigarettes).

9. PUBLIC HEALTH CONSEQUENCES OF E-CIGARETTES
Conclusion There is conclusive evidence that e-cigarette devices can explode and cause burns and projectile
injuries. Such risk is significantly increased when batteries are of poor quality, stored improperly or are being modified by users
Conclusion 7-1. There is substantial evidence that e-cigarette aerosols can induce acute endothelial cell dysfunction, although the long-term consequences and outcomes on these parameters with long-term exposure to e-cigarette aerosol are uncertain.
Conclusion 8-1. There is substantial evidence that e-cigarette use results in symptoms of dependence on e-cigarettes
Conclusion There is substantial evidence that e-cigarette use increases risk of ever using combustible tobacco cigarettes among youth and young adults.
Conclusion There is moderate evidence for increased cough and wheeze in adolescents who use e-cigarettes and an association with e-cigarette use and an increase in asthma exacerbations.

Levels of Evidence Defined:
Conclusive evidence: There are many supportive findings from good-quality controlled studies (including randomized and non-randomized controlled trials) with no credible opposing findings. A firm conclusion can be made, and the limitations to the evidence, including chance, bias, and confounding factors, can be ruled out with reasonable confidence.
Substantial evidence: There are several supportive findings from good-quality observational studies or controlled trials with few or no credible opposing findings. A firm conclusion can be made, but minor limitations, including chance, bias, and confounding factors, cannot be ruled out with reasonable confidence.
Moderate evidence: There are several supportive findings from fair-quality studies with few or no credible opposing findings. A general conclusion can be made, but limitations, including chance, bias, and confounding factors, cannot be ruled out with reasonable confidence.
Conclusion Among youth and young adult e-cigarette users who ever use combustible tobacco cigarettes,
there is moderate evidence that e-cigarette use increases the frequency and intensity of subsequent combustible tobacco cigarette smoking.
