You're not the end user. You're the middleman who carries the legal and reputational weight if a product turns out to be non-compliant. So the first question isn't "is this a good vape?" It's "can I legally sell this in the US?"

FDA PMTA (Premarket Tobacco Product Application) is the gateway. Without it, a product is technically on the market illegally—and that's a risk you don't want to absorb.
