DRIVERS who use illegal drugs kill two people and injure about 60 others on Calderdale's roads each year.
The shocking statistics were revealed as the police said they were targeting drivers who take drugs as well as drink-drivers this Christmas.
Calderdale Council's road safety officer Peter Shepherdson said: "The problem of drivers taking illegal drugs is as big as drink-driving and possibly bigger.
"The taking of illegal drugs has increased dramatically over the last decade with UK research indicating a five-fold rise.
"Many motorists, especially those under 25, who would not drink alcohol and drive, appear willing to get behind the wheel after using drugs."
Now a major publicity campaign is under way to try to get them to realise the potential disastrous consequences of their actions.
It is called Think Drug Driving. Not A Safe Trip.
Mr Shepherdson said: "With drugs and driving we seem to be where we were 20 years ago with drink-driving.
"Many of the excuses we are hearing are the same as those used by previous generations of drink-drivers."
The most common drugs detected in drivers are cannabis, cocaine and ecstasy.
Mr Shepherdson said: "Effects can vary according to the type and amount of drugs taken, but drug drivers can experience slower reaction times, poor control, confused thinking and increased risk-taking."
Drivers suspected of being under the influence of drugs will be arrested and taken to police stations for a blood test.
If proved to be unfit to drive because of drugs they face a minimum one- year driving ban, up to six months jail and a fine up to £5,000.
