DRUG LINKED TO MENTAL PROBLEMS

Law Enforcement Is Focusing More on Small-Time Dealers Than Before.

WASHINGTON (AP) -- Youngsters who use marijuana are more likely to develop
serious mental health problems, the government said Tuesday. A private
group said law enforcement increasingly is targeting people who smoke and
deal the drug.

Past medical studies have linked marijuana with a greater incidence of
mental disorders such as depression or schizophrenia. But questions remain
about whether people who smoke marijuana at a young age are already
predisposed to mental disorders, or whether the drug caused those disorders.

Government officials say recent research makes a stronger case that smoking
marijuana is itself a causal agent in psychiatric symptoms, particularly
schizophrenia.

"A growing body of evidence now demonstrates that smoking marijuana can
increase the risk of serious mental health problems," said John P. Walters,
director of the White House Office of Drug Control Policy.

Administration officials pointed to a handful of studies to make their
case. One, from the Substance Abuse and Mental Health Services
Administration, found adult marijuana smokers who first began using the
drug before age 12 were twice as likely to have suffered a serious mental
illness in the past year as those who began smoking after 18.

The ratio was 21 percent to 10.5 percent. Those who first started as teens
also were at significantly higher risk.

Also Tuesday, The Sentencing Project released a report that found the
government's "war on drugs" has become the "war on drug" as police agencies
increasingly target marijuana.

Begun in the 1980s, the war on drugs was aimed at stopping large-scale
narcotics traffickers, particularly those selling cocaine. But since 1990
more of the focus has been on catching users and low-level dealers. And
more often than ever, the drug targeted is marijuana, according to the
group, a national nonprofit organization that works on judicial reform and
favors alternatives to jail.

A Breakdown of Figures

Of some 700,000 marijuana arrests in 2002, 88 percent were for possession,
it said. And only one of every 18 of those arrests ended in a felony
conviction.

"Arresting record numbers of low-level marijuana offenders represents a
poor investment in public safety" and diverts resources from "more serious
crime problems," said Ryan King, co-author of the report.

King found that in 1992 arrests for heroin and cocaine comprised 55 percent
of all drug arrests and marijuana 28 percent. A decade later, heroin and
cocaine arrests accounted for less than 30 percent of all arrests, while
marijuana's share had risen to 45 percent.
