The Association of British Drives (ABD) believes that drug driving should be tackled but urges the Government not to introduce knee jerk reaction laws which could punish a large number of innocent drivers.

ABD chairman Brian Gregory comments: "Like it or not, drug use is widespread amongst the younger population.

“Unlike alcohol, some drugs show up in 'drugalyser' tests many days after any effect has worn off.

“Whilst the irresponsible must be punished, safeguards must be put in place to ensure that what could be significant numbers of people who have acted responsibly, by not driving while under the influence of drugs, are not unfairly punished by traffic laws.

“Any action against such individuals should use legislation on possession or use."
