Yes, certainly. The fact of the matter is that electronic cigarettes have so many different aspects that need to be regulated. So much more research needs to be done and continues to be done. One aspect is e-liquid testing. For example, there's e-liquid flavouring. The flavouring that's used in e-liquid is food-grade flavouring, but nobody has ever evaluated the effect of food-grade flavouring on inhalation. That needs to be continuously tested, but our regulatory frameworks don't really support that effort.
We've also been advised that fitting this product into a natural health product category doesn't really work. It would require a health claim that we don't want to make. We don't want to make a health, therapeutic, or cessation claim.
