In a federal funded research study, which can be read about more here, a team of researchers wanted to study treating OCD with CBD. They did this by injecting rats with Meta-chloro-phenyl-piperazine (mCPP). This is a compound found in the drug, ecstasy. This compound induces panic attacks and OCD-like effects in mammals. After the rats were initially injected, they were put in a sand-filled cage with a few dozen marbles. Almost immediately the rats began burying the marbles. This is an OCD-like effect caused by the mCPP compound.
After observing this effect, the rats were then given liquid CBD. Almost immediately, their behavior changed. Almost all rats stopped this marble-burying side effect and began to resume normal function. All psychotic induced behavior was ended and normal brain function was observed.
