Winning the War on Drugs - The Rat Park Experiment
- 5 years ago
In 1978, Canadian psychologist Bruce K. Alexander conducted an experiment that would revolutionize the way we understand drug addictions. With funding from Simon Fraser University, Alexander and his colleagues built a large colony to house rats, with more than 200 times the floor space of a standard lab rat cage. This “Rat Park” experiment culminated in the leading breakthrough of the time: the underlying connection between a person’s environment and addiction.
Pitfalls With Previous Rat-Based Studies On Drug Addiction
The Rat Park Experiment aimed to prove that psychology – a person’s mental, emotional, and psychosocial states – was the greatest cause of addiction, not the drug itself. Prior to Alexander’s experiment, addiction studies using lab rats did not alter the rat’s environment. Scientists placed rats in tiny, isolated cages and starved them for hours on end. The “Skinner Boxes” the rats lived in 24/7 allowed no room for movement and no interaction with other rats.
Using the Skinner Boxes, scientists hooked rats up to various drugs using intravenous needles implanted in their jugular veins. The rats could choose to inject themselves with the drug by pushing a lever in the cage. Scientists studied drug addiction this way, using heroin, amphetamine, morphine, and cocaine. Typically, the rats would press the lever often enough to consume large doses of the drugs. The studies thus concluded that the drugs were irresistibly addicting by their specific properties.
However, rats by nature are social, industrious creatures that thrive on contact and communication with other rats. Putting a rat in solitary confinement does the same thing as to a human, it drives them insane. If prisoners in solitary confinement had the option to take mind-numbing narcotics, they likely would. The Skinner Box studies also made it incredibly easy for rats to take the drugs, and it offered no alternatives. The need for a different type of study was clear, and Alexander and his colleagues stepped up to the plate.

Pitfalls With Previous Rat-Based Studies On Drug AddictionThe goal of Alexander’s Experiment was to prove that drugs do not cause addiction, but that a person’s living condition does. He wanted to refute other studies that connected opiate addiction in laboratory rats to addictive properties within the drug itself. Alexander constructed Rat Park with wheels and balls for play, plenty of food and mating space, and 16-20 rats of both sexes mingling with one another. He tested a variety of theories using different experiments with Rat Park to show that the rat’s environment played the largest part in whether a rat became addicted to opiates or not.
