Chong on the comeback

After all he's been through in the last year or so, it's good to see things are looking up for Tommy Chong.

Since his July release from prison, he has been finishing an autobiography and plans to return next year to "That '70s Show" and his recurring role as Leo, the stoned-out, aging hippie. He doesn't know yet how his absence will be explained.

After that, there is the long-awaited return of Cheech and Chong. He and Cheech Marin haven't made a film together in 20 years, but a new one is in the works.

Ironically, the world's most well known stoner says he hasn't smoked marijuana in two years. He advises it wasn't hard to give it up because it's not physically addictive.
