Cannabis march attracts thousands
Police say they will arrest anyone smoking cannabis
Thousands of people have taken part in a demonstration for the legalisation of cannabis in London.
An estimated 5,000 people set off from Brixton at 1200 BST heading for Clapham Common for a "celebration of cannabis".
There was a large police presence at the beginning of the march because security has been tightened in the wake of the three nail bombings in recent days.
Another march protesting at the bomb attacks set off from Lambeth Town Hall to Trafalgar Square at 1300 BST.
Cannabis users 'ignored'
The drugs protest was part of a worldwide day of events organised by activists of the International Cannabis Coalition.
It believes that the use of cannabis is widespread and that many otherwise law-abiding sections of society were being categorised as criminal.
A group spokesperson said: "The law is being held in disrepute and over seven million cannabis users are being ignored by politicians at their peril."
