Channel Four's Jon Snow (and not the Game of Thrones one) has opened up on his blog about what it felt like to get really (really) stoned for an upcoming documentary for Channel 4 called 'Drugs Live: Cannabis On Trial' programme.

The 67-year-old news presenter took part in the experiment which was a “Home Office-approved, NHS-supported trial of skunk". It involved three separate appointments; "One session was to involve street strong skunk that so many consume. Another session was to involve ‘adulterated skunk’ in which the drug’s two worst chemicals had been removed. Another was to involve a placebo."

The presenter then said he knew straight away which one was the cannabis and while he had taken the odd puff or two of the drug in the past, this was a completely different experience; "I felt as if my soul had been wrenched from my body. There was no one in my world. I felt I had lost all control and had only the vaguest awareness of who I was and what on earth I was doing. I cascaded into a very, very, dark place, the darkest mental place I have ever been. I was frightened, paranoid, and felt physically and mentally wrapped in a dense blanket of fog. I lost all sense that I was being filmed by Channel 4."

So yeah, the dude was well and truly baked, and TERRIFIED, he said.

"I’ve worked in war zone but I’ve never been as overwhelmingly frightened as I was right then – and as I emerge from the scanner you see me blearily sitting up and hugging young Dr Rebecca for my dear life, as if she was my mother."

Crikey. If he keeps at that he'll soon know nothing! No? Anybody? No. Sorry.
