Smithsonian Magazine recently ran an article, Ads for E-Cigarettes Today Hearken Back to the Banned Tricks of Big Tobacco, about E-Cigarette Ads utilizing techniques that were already banned (in the US) by combustible cigarettes.
I've done freelance work for a Vapeshop before. Thinking back on the services I provided I don't believe any could've been at all considered predatory, though I may be forgetting one. I dropped them as a client a long time ago because of moral reasons anyway.
This does beg the question though - as a designer do we have any legal obligations to be aware of predatory design practices? If vape advertising does get regulated in the way that combustible cigarettes are regulated then does any of that burden fall on us, the designers? Or should we accept the job, get paid, and leave the legal fallout entirely up to the client?
