No one is jailed for becoming addicted to a drug.
They are jailed for purchasing, possesing, or selling illegal, controlled, or restricted substances in violation of the law.
Ah, but the LP'ers believe Limbaugh should go to jail because he confessed to being addicted, and by logical extension (yes, I know, logical and LP don't go well together) he obviously broke the law getting his drugs...AND the National Enquirer says he broke the law.
Now that is a pretty open and shut case for many of them.
