Guarantee is a much stronger word than I would use, and I'd be interested in the cost/benefit analysis that goes on there. I would imagine an incomplete PMTA would be rejected in much less than a year.Filing pretty much guarantees an e-liquid company an extra year in business. And it's a year when there will probably be a lot fewer competitors.
Sorry, I didn't mean that all users did that, just that the regulators assumed that all users did that. I preferred lights/blues myself, the reds/filters were too harsh for me.Some consumers (myself included) actually preferred "light" cigarettes pretty much the whole time (3-1/2 decades) we were smoking.
