Comparative Study
Conventional and electronic cigarettes (e-cigarettes) have different smoking characteristics.
Electronic cigarettes or e-cigarettes are marketed as tobacco-free nicotine delivery devices that have received little laboratory evaluation. In this study, the smoking properties of conventional and e-cigarettes were compared by examining the vacuum required to produce smoke (conventional cigarettes) or aerosol (e-cigarettes) and the density of the smoke/aerosol over time. ⋯ Generally, e-cigarettes required stronger vacuums (suction) to smoke than conventional brands, and the effects of this on human health could be adverse. The amount of aerosol produced by e-cigarettes decreased during smoking, which necessitated increasing puff strength to produce aerosol. The decreased efficiency of aerosol production during e-cigarette smoking makes dosing nonuniform over time and calls into question their usefulness as nicotine delivery devices.

Less than half of college students who have smoked in the past month identify themselves as smokers. Thus, we examined (a) how college students define the term "smoker" and (b) how this definition impacts smoking behavior and attitudes. ⋯ College students use a broad range of criteria to define who is a smoker. These criteria impact how motivated students are to quit smoking and their perception of needing to "quit smoking."

Randomized Controlled Trial
Effects of smoking cues in movies on immediate smoking behavior.
The objective of this study was to investigate the effect of smoking cues in movies on immediate smoking behavior. We tested whether smokers who are confronted with smoking characters in a movie smoke more cigarettes while watching than those confronted with non-smoking characters and whether this effect is less profound when smokers are more involved in the narrative (i.e., transportation). ⋯ These results call for (a) increasing the awareness among people about the effect smoking cues in movies might have and (b) stricter control over smoking cues in movies.

As little is known about the policy making process around smokefree car laws, we aimed to investigate policy makers' views about such laws in a setting where these have not yet been enacted but where published evidence exists on the hazard of smoking in cars and on relevant public support. ⋯ In this particular policy setting, there appear to have been assumptions by policy makers about the dominance of adult "privacy" over child protection. The lack of awareness in this particular (NZ) policy community of national-level public support for banning smoking in cars with children and of the progress elsewhere on such laws also suggests the importance of information and advocacy if such laws are to be progressed.
