Dr. Glantz's comments on the lack of health benefit in cutting down on one's smoking come in response to one of the reported benefits of electronic cigarettes: that they help many smokers to cut down substantially on the amount they smoke. Glantz : "Dual users, who simultaneously use both products, are unlikely to see much, if any, health benefit because of the continued cigarette use, even if daily consumption drops." In other words, if you are still smoking, there are no benefits from cutting down on the amount you smoke thanks to e-cigarettes.

Thus, before even conducting the study, these researchers have concluded that adult smokers and their family members are severely affected if they undergo surgery and return to a THS-polluted environment, because their healing process will be significantly delayed. Also, the researchers have concluded that individuals who are repeatedly exposed to thirdhand smoke have impaired healing. This includes elderly parents in households with smokers as well as housekeepers in hotels.
