If you need more vapor, get some e-liquid with more vegetable glycerin (VG) in it. The liquids that produce a ton of vapor usually contain a higher VG blend to bring out the vapor and reduce the sweetness. As a rule of thumb, the more VG, the more vapor and less taste. On the other side, the more PG in the e-juice, the more you taste the flavors, but the less vapor production you will have. I like my e-liquid mixed with 70% PG and 30% VG, but this is a personal preference.

The very idea that one would extrapolate from a study finding that vaping, like smoking, reduces exhaled nitric oxide levels to the conclusion that smoking may be no more hazardous than vaping in terms of its acute pulmonary effects defies scientific logic. It also shows a misunderstanding, or at least a misinterpretation of the meaning of exhaled nitric oxide findings.
