To your first question, I apologize, but my French is horrible.
I do think we have sufficient research around advertising because of the links back to tobacco advertising. Tons of work has been done there. We know the effect of advertising on youth especially, but also on non-smokers.
I think the e-cigarette industry has hit the rewind button and we've taken things back 50 years as far as their approach in advertising is concerned, using celebrity spokespeople and making it look glamourous and sexy—but we know all f that. So if we have to focus somewhere, I would say focus on the products themselves, testing their efficacy as a cessation device, and then on the unintended negative consequences of their use as well.
