Looks like he did about 15 years according to ths:
The biggest and most sophisticated marijuana smuggling organization in California history had its roots here in Berkeley, Richmond and Orinda. Details of the incredible operation of Bruce J. Perlowin came to light in September after the King of Pot was brought to the Bay Area from Texas as part of the federal government’s ongoing investigation into his 200-man international organization.
Perlowin, a ponytailed, bespectacled, studious and mild-mannered man who looks more like Mr. Peepers than one of the world’s biggest drug dealers, is currently fighting government efforts to have him testify before a federal grand jury in San Francisco. He is being held temporarily in a San Francisco sheriff’s department cell at the Hall of Justice. Assuming a semi-lotus position during a series of jailhouse interviews, he said he turned down offers by federal prosecutors to let him “walk,” and took a 15-year prison term rather than snitch on his former employees.
