Officers from the Lancs Specials team had been searching for a high risk missing person when they came across a red SEAT Leon in the town.
Police found two men in the car which contained drugs and 'large amounts' of cash.
The driver was arrested on suspicion of drug driving and the passenger received a fine for breaching Covid-19 regulation.
In a tweet on the LancsSpecials Twitter page, Sp Sgt Jake said: "Busy night covering as a Morecambe van.
