Parliament Square, London, UK. 1st August, 2015. About 50 pro psychoactive substance activists gather in Parliament Square in London to inhale nitrous oxide, otherwise known as laughing gas. The demonstration was organised by several groups, including the Psychedelic Society of London, to protest against the psychoactive substances bill, which last week passed its third reading in the House of Lords. As Big Ben struck 3pm the activists simultaneously inhaled their nitrous oxide filled balloons resulting in the inevitable collapse of fits of giggles. Pictured: Organisers fill nitroius oxide filled balloons and distribute them to the crowd. /
