US studies looking into e-cigarette use behavior patterns amongst the same age group, found that a number of factors were involved in this. Some studies found that personality factors, curiosity and the “cool factor” played a main role in enticing teenagers to initiate vaping. This reflects arguments by tobacco harm reduction experts who have long been pointing out that the existence of flavours is not the main cause of teen vaping and that those likely to vape would be smoking in the absence of the safer alternatives.
Other studies found that lifestyle factors played a role, whilst others indicated that teens who crave excitement are more likely to use multiple illicit substances, including tobacco and vaping products. Researchers Kevin Tan and Douglas C. Smith, found that those teens who are less satisfied with their lives and seek out risky and exciting experiences are the ones more likely to use multiple illicit substances regularly, including nicotine via e-cigarettes. Additionally, found the study, the participants’ attitude towards vaping also reflected how they viewed other substances.
