People can now take drugs at festivals without being arrested (UK)

I heard about this on the news this morning but hadn't heard enough to post.

The first festival in the uk to ever allow drugs in and to be tested.

Personally I think this is amazing. People are going to take drugs into a festival and use them illegal or not. By being able to test drugs and ensuring no one will be prosecuted it will hopefully stop/decrease the chance of death by taking drugs that have been tampered with.

What do you think of the new initiative?

Also want to add that I myself, am anti drug. I know people who do it, that's fine, I would never ever myself just because I know first hand what it does to people.
