A PEER who is campaigning to legalise low-potency cannabis says the debate has been reignited after Theresa May told him in a letter that she shared his “concerns over the use of skunk”.

Lord Monson, of Burton in Lincs, lost his youngest son, Rupert Green, 21, to the drug on January 23 this year. Rupert died in hospital having tried to kill himself and after prolonged periods of psychosis and aggressive behaviour.

Lord Monson attributes his death to skunk – a particularly potent form of cannabis.

“I didn’t know what the difference between skunk and cannabis was,” he said. “I thought skunk was just a generic word the young use for cannabis. I assumed it was just a rite of passage. It was only when he became mentally troubled and said he was going to commit suicide that we realised how serious it is.”
