The levels of toxic substances in vapes are usually orders of magnitude lower than in tobacco smoke. The references you adduce provide no information in support of FDA's attack on vapes. The BMJ article summarizes the low reliability of research on vapes, the FDA memo shows the nicotine used in vapes is distilled from tobacco, and the third one shows actually a reasonably good level of precision in labeling of nicotine content of vapes. Diethylene glycol at 1%? Ah the horror! This would result in a 10 mg of daily dose, or 1/10 000th of a deadly dose! </div><div><br></div><div>Also, you are engaging in manipulative rhetoric ("garbage-quality product"). Try not to give garbage references next time.</div><div><br></div><div>Rafał</div></div>
