This week, three MPs told Radio 1 Newsbeat they think cannabis will become legal in the UK within a decade.

David Lammy, Jonathan Djanogly, and Norman Lamb had been on a fact-finding trip to Canada, the first major Western country to legalise the drug.

They were speaking to us as part of our documentary Legalising Weed: Canada's Story.
