Police fined a pregnant woman after finding her in possession of cannabis in Loudwater.
Officers stopped a Mini driver on London Road and found two people with the Class B drug.
A warning was given alongside a £90 fine for possession of cannabis.
The vehicle was also seized as officers found the driver to be disqualified from driving and had no insurance.
The driver has since been reported to the courts by Thames Valley Police (TVP).
A TVP spokesperson said: "Officers from the Chepping Wye Valley team stopped this Mini on the London Road in Loudwater.
"There was a strong smell of cannabis from the vehicle and both occupants were found to be in possession of the devil's lettuce.
"Rather concerning was that one of the occupants was pregnant.
"Things didn't end there though as the driver of the vehicle was disqualified from driving and had no insurance."
