A couple thoughts to add....
A) Cadmium itself is NOT toxic in certain solid forms; for instance we get parts cad-plated all the time. For aerospace / mil electrical connectors this is a practical (and only) choice when stainless steel won't work. Now -WHERE_ you get your parts plated is another story, since the process itself is a bit toxic and requires safe disposal / PPE. It does get expensive. Harmful? No, not in certain forms. Ship to EU?? Of course if its essential to aerospace / stationary industrial or telecom equipment...a least it was OK last month. That's like leaded solder...if it HAS to work with some "banned" substance then EU will let it in, RoHs is more strict for consumer devices for sure.
Handling a cad plated screw is NOT going to kill you, and never was dangerous in a typical handling situation.
Snowboards are millions of times more harmful, and yet you can buy those anywhere. It's weird how politicians decide what is dangerous or not for us naughty children to play with. For instance: If it comes down to protecting the Earth, then let's ban Sex: That creates people, and people harm the Earth, therefore let's get on with reducing the population...The political arguments are useless when carried too far.
B) If you crimp or press fit your conductive parts together FIRST, so there is a solid mechanical connection between copper to copper conductors, the solder ain't gonna make any difference - it's not part of the conductive current flow path.
Look at well designed older equipment and look at how the copper wire is crimped or overwrapped with a copper wire cinch or sleeve crimped onto the output connector and wire - THEN soldered. That way you don't need cad solder in the first place.
So a lot of the time you don't even need Cad solder, other times it's handy when used only when you really need to. Just ventilate your soldering area, keep your hands clean and don't eat cad OR lead solder for dinner and you'll be perfectly fine.
