'Home Improvement': Where Are They Now?

The youngest star of "Home Improvement," Taran Noah Smith, has left show business, but he's still making headlines.

Smith, who played the youngest of Tim Allen's kids on the '90s sitcom, was arrested Feb. 1 and was later charged with driving under the influence and possession of hashish. Last week, Smith pleaded guilty in California to drug possession and no contest to a "wet reckless" charge (which replaces a DUI in a plea-bargained settlement), according to On The Red Carpet. His sentence included a six-month drug-diversion program, three years probation and a fine.
