Shifty Drug is a product that appears in the Cars series.
Shifty Drug is a simple drug product, although it is unknown whether it is a normal pharmacy drug or a prescription drug.
It initially appears only on the boards above the garages and pit road on Motor Speedway of the South and Smasherville International Speedway, but later appears on many walls and billboards in Cars: Mater-National Championship and Cars: Race-O-Rama.
- Diecasts and shots from the movie of a Shifty Drug car numbered 35 exist, but there is no game incarnation of this car.
- On the Wii version of the first game, cars are given their unique pits, but even though no car sponsors for the product, there is a Shifty Drug pit. There also are pits for Gask-Its and Easy Idle, but no actual car.
