A factory worker will have to rely on colleagues to help him get to work after he admitted two counts of drug-driving.
Maciej Grymek, 33, of Hockham Street, South Lynn, was banned from driving for 23 months after pleading guilty during a court hearing on Monday.
The court heard Grymek had been driving a BMW when he was stopped by police on London Road, Lynn, on December 21.
He was arrested after testing positive for the presence of cannabis in a roadside assessment.
Later tests showed he had 7.7 micrograms of the drug in a litre of his blood. The legal limit is two.
He was also found to have 12 micrograms of methamphetamine in his blood. The legal limit is 10.
Mitigating solicitor Ruth Johnson said Grymek expected to lose the opportunity of a promotion at the factory in Attleborough where he works, but would continue to work there.
Grymek was fined a total of £500 and told to pay £85 costs, plus a £50 victim surcharge.
