Drugs Live: Jon Snow, Jennie Bond, and unexpected successful people who have admitted to smoking cannabis

Barack Obama, Boris Johnson and she of pink bus fame Harriet Harman are among the names who have dabbled in the drug in the past

“Do I want food? Not particularly – unless it's grapes,” Jennie Bond giggled.

About 75 minutes into her Home Office-approved, NHS-supported trial of skunk, being filmed for Channel 4’s Drugs Live programme which airs at 10pm, it becomes evident that the former royal correspondent has the munchies.

“What was happening to me outstripped anything I have ever experienced,” he said, having sucked in “two huge balloons” of skunk.

“By the time I was completely stoned I felt utterly bereft,” he continued. “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.”

They’d decided to test the drug on the unlikely human guinea pigs following reports that 25 per cent of all psychosis treated in Britain is associated with smoking skunk.

But it turns out, they aren’t the only surprising names who have ever experimented with cannabis. Take the unlikely candidates above, for example.
