Volunteer litter pickers have revealed that they've recently recovered a staggering 2,217 large canisters of laughing gas from around Cardiff. Local clean-up crew Cardiff Rivers Group made the shocking admission after posting on Twitter a photo of its latest huge haul of discarded nitrous oxide containers.
"A further 172 canisters made safe and taken for recycling," they tweeted, alongside a pic of an outsized bag stuffed full of the offending items - which one neurologist has dubbed 'more dangerous than cocaine'. "This brings the total to 2,217 canisters removed by our volunteers from around the streets and parks of the capital.
"Well done and thank you to everyone who helps make a difference to where we live." The accompanying image showed multiple canisters - much larger than the often-seen silver ones known as 'balloons' or 'chargers' - produced by a brand called Cream Deluxe. Each contains what's described online as "640g high purity food-grade N2O for extraordinary cocktails."
