Erik Lindeman is chief physician at the Poison Information Center.

He tells SVT Nyheter that he

does not

think Ukraine's foreign minister's warning was excessive or paranoid.

- It may sound completely insane that you should be afraid to touch a pen, but what the Foreign Minister says is not taken out of thin air.

These are not agent stories, but this is what has happened in the Soviet Union, and in today's Russia.

The use of poisons has accelerated during the Putin era.

There are absolutely amazing things.

In the video above, you can see the chief physician demonstrating how a Russian poisoning at the negotiating table could go, and what happens if you put on a pencil with novitjok on, or get polonium in you via a piece of food.
