Drug-driving limits
[ch 5: pages 83-84]New drug-drive legislation came into force from 2 March 2015 in England and Wales. The new law sets limits at very low levels for eight drugs commonly associated with illegal use such as cannabis and cocaine, but also includes eight prescription drugs:
• clonazepam
• diazepam
• flunitrazepam
• lorazepam
• oxazepam
• temazepam
• methadone
• morphine
The limits set for these drugs exceed normal prescribed doses. The coalition government brought in the new limits and advised that the vast majority of people can drive as they normally would, so long as:
• they are taking their medicine in accordance with the advice of a healthcare professional and/or as printed in the accompanying leaflet; and
• their driving is not impaired.
There is a medical defence if a driver has been taking medication as directed and is found to be over the limit, but not impaired. The Department for Transport road safety campaign THINK! advice is that drivers who are taking prescribed medication at high doses should carry evidence, such as prescriptions slips, with them when driving in case they are asked to take a test by the police.
The TUC expressed concern about the new limits and says they are not safety-based and could lead to a “big increase” in drug testing at work and in workers being disciplined or fired for being over the limit, despite no evidence of an impairment.
It advises those working in a safety-critical job or who drive for work to let their employer know if they are taking any medication, as well as reading the instructions and seeking advice from their pharmacist or doctor.

A bus driver falsely accused of driving under the influence of cocaine recently won compensation for unfair dismissal after he was wrongly dismissed from First Bristol Ltd for “gross misconduct” having tested positive for cocaine in a workplace drug test:
Thompsons Solicitors represented the general Unite union member, Alan Bailes, and reported that he had handled several hundred pounds of cash, which research shows is commonly contaminated with cocaine. It said that First Bristol Ltd used saliva tests on its employees to identify whether they had consumed illegal substances. But Mr Bailes was not invited to wash his hands before the drug test and had to handle the swabs used to collect his saliva sample both before and after. The fact that he had eaten his sandwiches just before the test increased the chance of hand to mouth contamination.
There is no national standard or government endorsed cut-off level for saliva testing and, as a result it is sometimes considered unreliable, particularly when compared with urine or hair testing, which is regularly accepted by the courts.
At his personal expense, Mr Bailes provided a hair specimen covering a history of 90 days and the result was negative for cocaine and its metabolites. Despite this new independent evidence, according to Thompsons, First Bristol Limited refused to reinstate Mr Bailes, who had no previous disciplinary record in his 22 year-career history.
The tribunal ruled that Mr Bailes should receive the maximum compensation that could be awarded for his unfair dismissal. It entirely accepted that his future career prospects had been affected by the unfair dismissal, and that there was an onus on the employer to carry out proper investigations before dismissing such a long-serving employee with an impeccable record.
