Parliament will debate the legalisation of cannabis next month, House of Commons authorities have announced.

MPs will consider a proposal to make the “production, sale and use of cannabis legal” on Monday 12 October.

The debate will be held in response to an official petition on the Parliament website that has received over 211,000 signatures as of early September.

The debate will be led by left-wing Labour MP Paul Flynn, a member of Parliament’s petitions committee.

Paul Flynn is a longstanding advocate of medical cannabis

Mr Flynn has previously called for the legalisation of cannabis for medical use, introducing bills in 1999 and supporting another in concert with Lib Dem MP Tom Brake in 2008.

Next month’s debate is unlikely to lead to any change in the law, though it could put pressure on the Government to act.

The Government’s official response to the petition was negative. It read: “Substantial scientific evidence shows cannabis is a harmful drug that can damage human health. There are no plans to legalise cannabis as it would not address the harm to individuals and communities.”

It said legalisation would “send the wrong message”.

Warren Where cannabis is and isn't legal Spain Despite cannabis being officially illegal in Spain, the European hotspot has recently started to be branded, ‘the new Amsterdam’. This is because across Spain there are over 700 ‘Cannabis Clubs’ – these are considered legal venues to consume cannabis in because the consumption of the drug is in private, and not in public. These figures have risen dramatically in the last three years – in 2010 there were just 40 Cannabis Clubs in the whole of Spain. Recent figures also show that in Catalonia alone there are 165,000 registered members of cannabis clubs – this amounts to over 5 million euros (£4 million) in revenue each month Getty Where cannabis is and isn't legal Uruguay In December 2013, the House of Representatives and Senate passed a bill legalizing and regulating the production and sale of the drug.

However a study published this summer in the US found that cannabis users were no more likely than normal to suffer mental health problems including depression, psychosis, or asthma.

While many countries across the developed world have moved to legalise or decriminalise cannabis use, the UK has moved to tighten restrictions on it in recent years.
