Road safety campaigners have demanded action to stop drivers taking ‘hippy-crack’ behind the wheel, amid fears its use is rife.
Videos and photos shared on social media suggest drivers inhaling nitrous oxide gas from balloons is widespread.
But while driving while high is illegal, the substance, also known as laughing gas, stays in the body only a short time and drug test kits cannot trace it, the Campaign Against Drink Driving said. Also, possessing the gas is not a crime – unless it can be proved there is an intention to supply.
