How many sessions were there in the sham experiment?
We used a randomized, sham-controlled, single-blind, three-period, within-subjects study design in which each subject participated in each experimental exposure and served as his/her own pre/postexposure control. In random order, participants underwent the following three exposure sessions, each separated by a minimum of 1-wk washout: 1) sham vaping, 2) vaping without nicotine, and 3) vaping with nicotine. A 3-h observation period followed acute exposure. While allocation and acute exposure was performed by an unblinded investigator who did not participate in any other aspect of the study, other experimenters were blinded to the study session. Participants were aware of the particular study session, since they saw the presence or absence of exhaled vapor. Twenty-one subjects performed all three experimental sessions. Two subjects finished two experimental sessions, and only one session was completed by two participants. We started data collection after 20 min of rest in a supine position in a noiseless and air-conditioned room at 23 ± 1°C. During the course of each experiment, the participant had to be silent and awake. The three study sessions for each participant began at the same time of day to avoid confounding by nychthemeral variation of cutaneous temperature and serum club cell protein-16 (CC16) concentration (1, 6). Participants were systematically screened for urine cotinine (semiquantitative detection threshold of 600 ng/ml; NarcoCheck, Paris, France) and urine tetrahydrocannabinol (semiquantitative detection threshold of 50 ng/ml, NarcoCheck), which had to be negative for inclusion. Fractional concentration of carbon monoxide (SineFuma, Breda, The Netherlands) during expiration had to be <5 ppm (17). Consumption of beverages with caffeine or alcohol, tobacco smoking, and physical exercise were not allowed for 48 h before each experimental session. A 12-h fasting state was required before each study session; participants could, however, drink water to avoid dehydration.

How many smokers were recruited for the Erasme study?
On-campus paper advertisements (Erasme University Hospital, Brussels, Belgium) were used to recruit 25 healthy occasional tobacco smokers from January 2017 to November 2017.

Before participants entered the study, we scheduled an interview during which subjects were randomly allocated to the three experimental sessions according to a computer-generated randomization list. A medical history and physical examination were also obtained during this interview. Healthy participants were defined as follows: 1) no acute or chronic illness, 2) no history of cardiovascular symptoms, 3) blood tests within the normal range, 4) no use of medication except oral contraceptives, and 5) no hypertension as defined by clinical guidelines (67). We also verified that volunteers were able to vape at high wattage without any symptoms of airway irritation; if participants were unable to do so, they were excluded from the study. All provided written consent after a detailed explanation of the study design, which conformed to the Declaration of Helsinki. The study was approved by the local Ethics Committee. The study is registered at ClinicalTrials.gov ({"type":"clinical-trial","attrs":{"text":"NCT03036644","term_id":"NCT03036644"}}NCT03036644).
What is a PG e-cigarette?
Electronic cigarette (e-cigarette) liquid (e-liquid) is mainly constituted with propylene glycol (PG) and glycerol (GLY) in association with flavors and nicotine (15). PG is an aliphatic alcohol commonly used by industries as a humectant because of its hygroscopic properties and miscibility with water (18). GLY is an oily, hygroscopic liquid also used as a humectant (19). These molecules are “generally recognized as safe” (GRAS) for use as food additives (18, 19). When heated by an electric resistance wire (as in an e-cigarette), PG and GLY aerosolize with other substances, such as flavoring compounds and nicotine (15). This aerosol consists of a suspension mixture of gases, vapors, and aqueous particles. The latter elements condense in submicrometer to micrometer size droplets that can be inhaled into the lungs (i.e., “vaped”) (35, 52).
How long to draw arterial samples after vaping?

Air bubbles were removed from samples, which were gently mixed and immediately analyzed on an ABL90FLEX machine (Radiometer Medical ApS) per manufacturer recommendations. The following arterial parameters were assessed: Po2and Pco2, pH, oximetry, electrolytes, and metabolites (69). The alveolar-arterial oxygen difference was calculated from the alveolar gas equation (60).
