The new drug driving law comes into play on the 2nd March in England and Wales.
It includes prescription drugs however as long as you are following the advice of a healthcare professional and your driving isn’t impaired you should be fine
The new law sets limits at very low levels for eight drugs commonly associated with illegal use such as cannabis and cocaine and eight prescription drugs that are included within the new law. They are: Cloanzepam, diazepam, flunitrazepam, lorazepam, oxazepam, temazepam, methadone andmorphine.
There will be a medical defence if a driver has been taking medication as directed and is found to be over the limit, but not impaired. The advice for drivers who are taking prescribed medication at high doses is to carry evidence with them, such as prescriptions slips, when driving in order to minimise any inconvenience should they be asked to take a test by the police.
