No surprise, I suppose, that Gore is denying this charge rather than use it as an excuse to raise the drug policy issue. I doubt the press will look further since they clearly were trying desperately not to have to publish this in the first place. Look at the attention payed to the readily admitted fact that the source has been in treatment for depression, the implication being that you can't believe this man.

  GORE DENIES BOOK'S CLAIM OF DAILY POT USE IN '70S

      An allegation in a soon-to-be-published book surfaced on the
campaign trail yesterday as Vice President Gore denied that his youthful
use of marijuana was more extensive than he has acknowledged.

The allegation was made by John Warnecke, who worked with Gore on the
Tennessean newspaper in the 1970s and gave his account to Newsweek
reporter Bill Turque for a biography of Gore.

Questioned about the charge by local reporters in Iowa, Gore said the
story was "old news" and denied Warnecke's account that for years they
smoked pot daily.  He said he used marijuana "when I came back from
Vietnam, yes, but not to that extent." Gore said in 1987 that his use of
marijuana, which began in college, had been "infrequent and rare."

Pressed further yesterday, Gore said: "When I was young, I did things
young people do; when I grew up I put away childish things." He did not
address his relationship with Warnecke.

The incident is the latest example of how media coverage of an
accusation--in this case by a recovering alcoholic who is being treated
for depression - can intrude on presidential politics. The Warnecke
charge created a ripple in media circles after Newsweek delayed a
planned excerpt of Turque's "Inventing Al Gore: A Biography" in part
because of concern about Warnecke's credibility.  Salon.com published an
interview Saturday with Warnecke, whose allegations were discussed on
"Fox News Sunday" and in yesterday's New York Post.

In an interview from his California home yesterday, Warnecke freely
acknowledged that he is taking prescription drugs for severe depression,
that his family has a history of mental illness and that he has
voluntarily been hospitalized for depression a number of times.  Now
living on disability, Warnecke said he considers himself an addict and
had also used cocaine but has had no alcohol or drugs for 21 years.

But none of that, said Warnecke, 53, changes the fact that he knew Gore
"very, very well" as a friend and next-door neighbor in Nashville and
later raised money for his campaigns.  He says Gore used marijuana until
the week he announced his candidacy for the House in 1976, or about four
years later than the vice president has maintained.

Warnecke said he told a different story in 1987, when Gore was gearing
up to run for president, because Gore repeatedly pressured him to
"stonewall" and "not to tell the truth" about their drug use.  He said
he felt "intimidated" by Gore.

"I made up a story that he smoked very little a couple of times and he
didn't like it," Warnecke said.  "He smoked a lot and he liked it."
Warnecke said he felt "guilty" about lying and decided to talk to Turque
because he "couldn't stand the pressure any more."
