Drug-drive regulations come into force

Greater Manchester Police says it will delay implementing new regulations aimed at stopping people driving while on drugs that have come into force in England and Wales for about two weeks as it needs more time to train its officers and examine the legal implications of the changes.

Police will be able to use "drugalysers" to screen for cannabis and cocaine at the roadside..

Drivers face prosecution if they exceed limits set for the presence of eight illegal drugs, including cannabis and cocaine, and eight prescription drugs, including morphine and methadone.

Officers will also be able to test for ecstasy, LSD, ketamine and heroin at a police station, even if a driver passes the roadside check.

Those using prescription drugs within recommended amounts will not be penalised.

The new rules run alongside the existing law, under which it is an offence to drive when impaired by any drug.

The existing penalties mean drug drivers already face a fine up to £5,000, up to six months in prison and a minimum one-year driving ban.
