I'm pretty sure I disagree with this line of thinking. Pigeon holing what we do in with tobacco products will provide the government with the immediate justification they need to tax the hell out of us after they've made the product virtually unusable.
I originally thought regulation might be a good thing but after educating a little and reflecting on personal experiences, I can no longer say such a thing. I think that juice manufacturers who proactively disclose their ingredients on their labels are wise in doing so. I also think that our best bet is for those who make juice on a mass level come together to agree to a set of "best practice guidelines".
I also think that vendors - specifically on the local front - should pull their heads out of their a$$es and hold themselves to standards in terms of WHO they sell to (at least two shops sell to kids locally), as well as HOW they position the product ("you can smoke these anywhere").
Worthy of note, many vendors, suppliers, and manufacturers are already setting/maintaining the bar in terms of standards.
I can say from personal experience, we do not need government oversight. We don't want or need the FDA to get involved and we don't need the government telling us how we should do what we do. From personal experience, government is good at taxing things to death and ruining some businesses to benefit others. They're not good at taking a real world, sensible approach to things.
