One in nine young Brits admit to having driven under the influence of drugs, reveals survey.
Even more alarmingly, three per cent of those said they do so at least once a month.
The survey was carried out by the road safety charity Brake which has been calling for roadside 'drugalysers' to catch motorists who are high.
"The risks of driving on drugs are huge, and the consequences devastating - yet a huge proportion of young drivers are taking this appalling gamble with their own and others' lives," the Sun quoted Brake's senior campaign officer Ellen Booth as saying.
"We need a ban on driving with illegal drugs in your system, and we need roadside drugalysers.
"The longer this takes, the more lives will be tragically lost," she said.
The survey's findings were released as the British government announced that the country's first ever drug-drive laws are being drawn up by a panel of experts.
They will consider the different effects of cocaine, cannabis, ecstasy and heroin on driving.
Current on-the-spot police tests can identify a driver's lack of ability but do not specifically identify that the driver has taken drugs.
