It does get worse.

This seems to ban not only the import, export, buying and selling in NY State of ALL ivory (i.e including marine and mammoth ivory etc.) but also it's "distribution" which presumably means you cannot even give it away.
I hate to say it, but I think we should all prepare ourselves for the day when ownership of unlicensed ivory or other CITES type products becomes illegal, and of course licensing will be made damn near impossible. I don't expect it will be banned completely tho', the licensing officers would object to that.
