I'm amazed how far the article twisted the situation using the passive voice and beating around the bush. I skimmed the article and for most of it I was thinking this was some sort of food safety thing. Turns out they're trying to police access to some ways people can kill themselves. There's certainly some arguments to be had about that, but the cloaked framing is utterly disingenuous.

Such bad journalism it took so long to work out if he put poison in this stuff or people were using it to poison themselves.

So it's curing salt but misuse can lead to death.

Unfortunately for this guy the UK is such a nanny state they'd probably go after him for murder if he sold a toothpick if it could take someone's eye out.
