Taking LSD might keep criminals out of prison.

A big study of more than 25,000 people under community corrections supervision shows the use of psychedelic drugs like LSD or so-called magic mushrooms leads to reduced recidivism and may help criminals stay out of prison.

This is the first research in 40 years to take a look at whether mind-altering drugs can help reform bad guys.

The researchers at the University of Alabama and Johns Hopkins say this runs counter to the way drugs are legally classified as well as the way they're perceived in society, and that there should be more study into hallucinogenics as treatment.
