The driver sped away instead of stopping and in his attempt to escape hit a shop window and collided with a police car.
When police caught up with him they said they found one gramme of cannabis, 120 firecrackers and €365 in the vehicle.
In an uninhabited flat for which the suspect had a key, 408 grammes of cannabis in 14 bags, 104 grammes of cocaine, a precision scale and other object were found, police said.
All the objects were confiscated and the man was arrested.
The 21-year-old allegedly admitted to the offences when he was questioned.
