It’s illegal to drive in England and Wales if legal drugs impair your driving. It’s also illegal if you have over certain limits of some drugs in your blood and you haven’t been prescribed them.
These sedatives and stimulants can impair your ability to drive, so talk to your doctor about whether you should do so.
- amphetamine, eg dexamphetamine or selegiline
- morphine or opiate and opioid-based drugs, eg codeine, tramadol or fentanyl
You can drive after taking these drugs, but they must be prescribed, and you must get a doctor’s advice and stick to their recommendations. This includes if they advise you not to drive while you’re taking them.
Although these laws don’t apply in Scotland and Northern Ireland, you could still be arrested if you’re unfit to drive.
