I heard it, too. Day 91. It was Zeller, but I think it was his answer to a question about a black market. After 90, no new products can enter the market without passing FDA approval, but the black market won't get going 'till way later, like about 2-3 years. He's been distorting and dodging so much, I think he's got himself confused.
The burden of proof is virtually impossible at this stage for new products. Age restrictions is most likely the core focus of day 90. I think we're all good with that. Online verification is old tech and face to face is even older.
I wish the FDA luck if they think they have any chance at effectively enforcing the new product part of day 90+. It would serve no real purpose and require way too much money and man power that in the end would prove to be a fruitless effort. What's the point if it will ALL be eradicated in 2 years. That's the real end goal.
Vendors should fully comply with age and advertising though. That will certainly be policed.
