In my day to day work smoking is being seen as being stalled actually with certain priority groups having extremely high smoking rates. Those who are indigenous, those with mental health concerns, LGBT youth etc... The largest tobacco prevention risk in my eyes is the grey are in which vape vendors have in the promoting of their products. Considering that a good portion of the highest selling brands are owned by tobacco companies and you see a "pro-smoking" commercial during the Super Bowl it's clear companies have found ways around marketing prohibitions.
