the whole gateway for babbies into smoking ruse is really tiresome.......first off, if you wanna look cool and blow big clouds, there are plenty of juices with 0mg of nicotine...a teenage vaper does not need to use nicotine to vape, and there is no reason for them to use nicotine unless they are trying to use nicotine on purpose.
Teenage smokers don't have the choice in controling the amount of nicotine in a cig, they are musch more likely to become addicted to nicotine through smoking.
as for a smoke free world....yeah right....didn't we try that with prohbition of alcohol and look how that worked out.
