A year ago, Californians voted against legalizing marijuana, and last
week the Obama administration decided to help them mean it.

The four US attorneys in California announced they would enforce
federal drug laws by reining in a pot industry that the state had set
up to be strictly nonprofit and medicinal but since has spread like a
Mexican drug cartel.

The number of pot shops ("clinics") in the Golden State has exploded
into a $1.5 billion business that even ships "medical" marijuana to
other states, the Feds charge, and that "has been hijacked by
profiteers."

"That is not what the California voters intended or authorized, and it
is illegal under federal law," said US Attorney Andre Birotte Jr.

The Obama administration - after appearing soft on marijuana two years
ago - is doing what state law enforcement refuses to do. And the
Justice Department is being smart about it by going after large-scale
growers, landlords who rent to large pot dispensaries, or banks that
finance growers. People using pot for medicinal therapy - which much
of the medical community disputes - are not being targeted.

The real message to California and 15 other states that have some type
of legal medical marijuana is this: You can't try to legalize pot
through a back door, such as exploiting its medicinal use to anyone
who claims to have a headache or anxiety attack.

Keeping a lid on marijuana isn't like Prohibition, as PBS documentary
filmmaker Ken Burns points out. Alcohol has long been too widely
consumed to ban completely. Pot smokers are a small minority. They are
containable, especially given the well-documented adverse side effects
of pot, notably on teens.

California's attorney general, Kamala Harris, needs to take this
problem seriously by getting tough on doctors who make big money
handing out authorization for pot use and by ensuring that the medical
marijuana industry remains nonprofit. "We have yet to find a single
instance in which a marijuana store was able to prove that it was a
not-for-profit organization," said US Attorney Birotte. He added that
six people in a North Hollywood dispensary were indicted for selling
hundreds of pounds of marijuana a month in New York and Pennsylvania.
"California's marijuana industry supplies the nation," said US
Attorney Benjamin Wagner.

The big question now is whether President Obama will buckle to
political pressure from pro-pot forces and ease up the federal
pressure on California's pot industry. A short-term clampdown won't
dampen the momentum of the pro-legalization crowd that uses almost any
ruse on the public.

Last year, Californians saw what an unofficial legalization was doing
to their state and voted against the official kind. Mr. Obama finally
got the message. And he should stay on message.
