I’ve worked in war zones but I’ve never been as overwhelmingly frightened as I was right then.
In a candid blog post on the Channel 4 website, broadcaster Jon Snow has revealed what was going through his head after he took "street strong skunk" as part of a television experiment.
The 67-year-old presenter was acting as a "guinea pig" in a "Home Office-approved, NHS-supported trial of skunk" for the channel's upcoming Drugs Live documentary due to be broadcast on 3 March.
Snow, who says he had been passed the odd spliff in the past but had never had more than two or three puffs, explained that on this occasion he was given two balloons of the drug and by the time he was stoned felt "totally bereft".
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.
After coming down from his high after about four hours, Snow explained that he felt a sense of euphoria and celebrated by drawing a "pastoral scene on an old box that was lying around in the lab".
He leaves the post with one important warning for everyone: "This is a dangerous, horrible substance."
