Norman Lamb took the drops in Canada where cannabis is legal

Bill Clinton smoked it but never inhaled. Andrea Leadsom tried it at university. Now a Liberal Democrat has become the first MP to be filmed taking cannabis on British television.

Norman Lamb, 61, a mental health campaigner, tried a sleep remedy on an all-party fact-finding mission to Canada where the use of recreational cannabis was legalised in October.

Mr Lamb, a former care minister, visited a Nova store where items were labelled with the amount of CBD, a non-psychotropic constituent of the plant, and THC, a psychoactive compound. The MP for North Norfolk was filmed by BBC Newsbeat in his hotel room using a pipette to put four drops of Solei balance oil under his tongue. The footage will be on iPlayer today.
