Oh, it's been discussed before. When I was researching Cozumel for a dive destination I did some reading about it. And, well, I 'know this guy' who went and had some in his baggage, who had a hairy moment in baggage claim when the drug sniffing dog checked his bags. The question, which this guy's advance research had not answered, was would a drug sniffing dog alert on a big that had Sudafed in it?i find this to be avery interesting conversation. funny i have never heard any talk online about this before.
From what this guy had to say, the dog did not, and things went smoothly. That's an anecdotal case of one.
Interestingly, there's an old 2018 thread discussing it regarding going to the Philippines. A 2016 Insider article said products containing pseudoephedrine were illegal in Japan.
