Legalizing marijuana makes sense, cents

common sense, not economic need, should persuade Americans it's past time for a sober look at our mad "reefer madness" laws. The Golden State legislator pushing the idea, Tom Ammiano of -- plug in the appropriate joke -- San Francisco, says licensing and taxing legal marijuana production and sales would earn California $1.3 billion a year. His bill would legalize marijuana possession and use for adults 21 or older, license commercial farming of it and tax it at $50 an ounce. A big problem: California can't do this on its own.
