Brain scans prove tanning can be as addicting as doing drugs or smoking.
A team of researchers from the University of Texas Southwestern Medical Center studied seven people who tanned often.
During one indoor tanning session, they were exposed to UV light, during another session the UV rays were filtered out.
They found the areas of the brain that play a role in a reward were activated when tanners were exposed to UV light.
These same areas are triggered when drug addicts do drugs or alcoholics drink.
The FDA is considering a ban on indoor tanning for people under 18.
